DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Generally, the present disclosure is directed to a new innovative, eco-friendly, sustainable, emission free, line of fully electric and silent, multi-purpose machines, equipment, services, and the like, for landscape, golf course maintenance, turf care, and the like. Such machines are mainly outdoor working machines and vehicles, with manned or unmanned autonomous operation, and built with remote wireless diagnoses, services, and the like, including a service provider system to perform a full range of service, and provide a work package coupled with leasing options to provide a service agreement with a one invoice per month package.
The present disclosure includes recognition that technology in machine and equipment design, and with respect to building such technology with increased use of electronics, electrical devices, information and communications technology (ICT), new types of power sources, automation, autonomous vehicle systems, and the like, has not being extensively used in golf course and turf care machines, and the like, nor has a service provider concept and business related thereto been extensively developed. The present disclosure further includes recognition that sustainability, eco-friendly designs, cleantech, environment and energy savings, and the like, are issues and requirements to be addressed for future developments.
In this respect, manufacturing of golf course mowing and related equipment is monopolized worldwide by handful of large, multi-billion dollar corporations, which merely watch and follow each other, without making technology leaps, and innovations, in order to limit risks. Accordingly, there are no newcomers in such markets, whereby golf industry customers, especially in Europe, are expressing that there are really no new innovations available, and that machines are basically built using decade old technology.
For example, golf course and other turf care machines, and the like, are mainly designed and built under the principle of employing one type of machine for each job, where each machine is built using different components, which requires an extensive selection of components, resulting in high costs for stocking, production and services, large amounts of required storage space for manufacturing, as well as at the premises of the customer. In addition, component standardization has been neglected in such design and manufacturing.
Further, as each job employs a different machine, there are employed a large number of different types machines, working and driving around the working areas and therebetween. By contrast, the present disclosure is directed to employing multi-job machines, built with multiple implements, for performing such jobs in one go, resulting in efficient work, lowered investment costs, and less trampling of the turf, less cultivation being needed, and the like.
Moreover, conventional turf care machines, and the like, are mainly built with combustion engines and extensively hydraulics, resulting in high emissions and energy consumption, as well as service and repair costs. In addition, such machines are prone to high energy costs, and energy leakage. Accordingly, the work performed by such machines cannot be considered as eco-friendly cleantech golf course maintenance, and turf care.
Still further, golf course operators want to have their courses open and free for game play and without maintenance machines interrupting the game play and causing combustion engine noise, and the like. By contrast, the present disclosure is directed to employing machines that can be programmed to work early in the morning or during the night, advantageously, increasing revenues from the more rounds golf that can be played. In addition, golf courses and turf care areas are normally nearby houses and/or resorts, hotels, and the like, so that combustion engine based machines with high noise levels cannot work at night, because they would disturb people living and sleeping nearby. In addition, in quite a number of countries in Europe, landscaping, golf course maintenance, turf care, and the like, combustion engine based machines are prohibited during weekends due to the high noise levels caused by such machines.
Accordingly, the competition between golf courses, and the ever increasing costs, will force golf courses to improve their efficiency, and increase the number of paid rounds and turnover. By contrast, the present disclosure is directed to employing automation, and autonomous silent, emission free, machines that address the above and other discovered problems with conventional machines, advantageously, attracting high paying customers, and providing noise and machine free greens, cleantech golf courses, and the like.
In addition, there is a need for a high green speed, which is an important parameter for rating golf courses. This can be achieved by cutting greens very short or by employing leveling rollers. However, cutting the greens very short stresses the grass, and the use of leveling rollers is an additional job to be performed, resulting in increased costs.
Further, there are number of jobs, seeds, fertilizers, chemicals, top-dressing, and the like, that are used in golf courses beyond merely mowing. Each such job requires a specific machine and operator, and such jobs result in trampling of the turf and the application of materials in an inaccurate manner. By contrast, the present disclosure is directed to employing multipurpose machines that perform such jobs in an accurate manner, by employing electronics, electrical devices, programming, ICT systems, automation, and the like, resulting in accurate navigation, and efficient and precise golf course maintenance, turf care, and the like. In addition, such electronics, electric devices, programming, ICT systems, automation, and the like, has not been extensively used in golf course and turf care machines, nor has a service provider concept and business been extensively developed.
Referring now to the drawings, wherein like referring numerical designate identical or corresponding parts throughout the several views, and more particularly to FIG. 1A, thereof there is illustrated an example of a golf course maintenance machine, according to an illustrative embodiment. In FIG. 1A, one or more machines 100 can be coupled via wireless communications links 134 and communications network 132 to a server 130 of a service provider for performing remote diagnosis and any other suitable functions, and the like, as further described.
FIG. 1B shows an illustrative embodiment of the electric, electronic, automation, and service provider based, autonomous working machine system 100 of FIG. 1A. In FIG. 1B, the machine system 100 can include a machine frame 101, a steerable rear wheel system 102 described with respect to FIGS. 1B and 2, front wheel system 103 described with respect to FIGS. 1B and 2, implement mountings 104 and 105 described with respect to FIGS. 1B, 4, 7 and 8, implement mounting hollow rectangular tube 106 described with respect to FIGS. 1B and 8, and steering system and column 107 described with respect to FIGS. 5 and 6.
The machine system 100 can further include quick exchange battery pack 108, electronics box 109 including central computer, internal and external communication systems, data collection with remote wireless diagnoses and service provider systems and programs, autonomous working machine electronics and programs, Battery Management System (BMS) 110 for controlling the battery pack system, touch screen user interface 111 for operating system (not shown) and wireless communication system (e.g., GSM, 3G or 4G, smart phone, etc.), charger 112, manual/automatic battery pack quick exchange system 113, battery pack lifting unit 114, receiver/antenna 115 (e.g., VRS GPS/GLONASS/GALILEA, etc.) and receiver/antenna systems 116 (e.g., VRS GPS/GLONASS/GALILEA, etc.) for autonomous machine operation and data collection for the central computer or server 130 and suitable computer programs thereof (not shown), clippings collection box 117 of an automatic clippings collection and dispersion system described with respect to FIGS. 10A-10B, and programmable cutting height selection and rotation speed programming systems described with respect to FIGS. 9A-9B. In further illustrative embodiments, the batteries of the machine 100 can be charged using suitable solar panels (not shown) located on the machine 100 and/or at a charging station.
The touch screen user interface 111 can include cellular phone, smart phone, and the like, functionality (e.g., Nokia, Windows, Android, Apple based, etc.). Advantageously, when starting the machine 100 for the first time, operators can uniquely identify themselves, for example, via a user login and/or bio-metric system having suitable readers (e.g., finger print, iris, facial, etc.) of the user interface 111, whereby suitable machine operating and safety instructions can be displayed on the user interface screen to the operator. In this way, the operator can confirm reading and understanding of the instructions in order to put the machine 100 in an operating mode. On subsequent operation of the machine 100, the operators can digitally sign in via the user interface 111 by identifying themselves via login and/or the bio-metric system. Advantageously, such functionality can be used to reduce of accidents, and prevent miss-use, theft, and the like, of the machine 100. In addition, such functionality can be used for operator efficiency rating, bonus payments, identifying accident prone operators, and the like.
The electric and electronic battery system with quick exchange battery pack provides for lower machine weight, and reduces aeration, ground trampling, and the like, due to the reduced wheel loads, and can use of braking energy to charge the battery pack. Advantageously, this can increase operation time between battery charging and reduce energy costs for increased sustainability.
In FIG. 2, various wheel patterns 3, 5 and 7 are shown for the frame 101. Wheels 103 in the front are followed by wheels 102 in the rear for tracking the free space 201 left by the front wheels 103. Advantageously, this provides leveling of the ground without leaving individual tire tracks, and with the load being evenly distributed and with a larger area of wheel prints on the ground due to the higher number of wheels, as compared to conventional machines.
In FIG. 2, the interchangeable drive power packs are described with servo motor 202, planetary gear 203 built into interchangeable drive unit 204 and placed inside interchangeable double wheel steerable power pack 205 and interchangeable double wheel none-steerable power pack 206. In this way, the wheels follow the ground by the swiveling of the double wheel bodies 205 and 206 via interchangeable servo controller 207, which can control various sizes of servo motors employed. Accordingly, interchangeable units can be used, for example, on 9, 11 to 15 wheel machines, as further described with respect to FIG. 14. Interchangeable power packs 205 and 206 can include interchangeable wheel rims, wherein the tires can employ a smooth surface or any suitable pattern according to the job. For automated quick return steering, the center wheels in front can raise up by raising unit 207, whereby the machine 100 can turn around a center point between the outer front wheels, without causing wheel marks on the ground, and for speeding up the work process.
In FIG. 3, different mowing units, including reel 301 and rotary 302 mowing units and/or illustrative implements (e.g., designed for different frames and wheel patterns from 3 to 7 wheel machines), such as fixed deck rotary mowing 303, snowplow 304, snow blower 305, brushing 306 units are shown on the various frame sizes and numbers of wheels (e.g., 3, 5 or 7 wheel), and which allow for operator visibility (e.g., as shown marked with an “x”) to the outer edge of the outer mowing units. Reel mowing mechanism 301 is further described with respect to FIGS. 9A-9B, and alternatively rotary mowing decks/units 302 are further described with respect to FIGS. 11A-11B. Reel 301 and especially rotary 302 mowing units and other implements can be built with an automatic clippings collection and dispersing system with respect to FIGS. 10A-10B, and can be modified in other applications. The machines with the 5 wheel configuration can have a 4 or 5 wheel drive with different battery pack sizes, according to the job being performed.
The machines of FIG. 3 can also be built with the configurations, where the outer mowing units are placed outside and in line with front wheels on 5 wheel and 5 mowing unit and 7 wheel and 7 mowing unit machines. Whereby one 5 wheel and 5 reel mowing machine can perform the mowing of greens, semi-greens/collars, Tees, fairways, and the like.
The 5 wheel machines of FIG. 3 can be built with longer wheel base, for example, as 7 wheel machines, and with an added capacity battery pack system. Instead of the bigger capacity battery packs, the automatic or manual quick exchange battery pack systems can be used to extend operating times. Advantageously, additional implements can be added, according to examples further described with respect to FIG. 8. In addition, the machines 100 shown on FIG. 3 can be built using well over 90% and up to 95% interchangeable components, resulting in reduced manufacturing costs, outsourcing, training, after sale servicing, logistics, and the like.
FIG. 4A shows an interchangeable implement lifting/lowering system 401 with a built in feature of subjecting implement down force and with innovative quick implement exchange and side-shifting. The system 401 includes linear motor 402, moving lever 403 that is pushed and pulled by linear motor 402, and which turns pulley 404. The system 401 further includes timing belt 405 turning pulley 406, whereby implement mounting arm 407 can move up or down to lift or lower implements fixed on swivel joint shaft 408, which moves up and down inside linear slide bearing 409 for automatic implement ground tracing and lifting and lowering, as further described with respect to FIGS. 7A-7B. The lifting/lowering system 401 is mounted on frame 411. Tempered and ground shaft 412 is mounted on the machine frame 411 at both ends with mounting units. Linear slide bearing or ball bushing or bearing bushing 413 allows the outer round tube 414 to turn around shaft 412 on lifting and lowering action. The square hollow tube (not shown) is fixed on tube 414 and rotates with tube 412. The fork (not shown) is fixed on mounting arm 407 and locking device 417 and allows implement mounting arm 407 to be changed quickly, resulting in quick changing of implements. Alternatively tube 414 is built with welded locking key 417, as shown on FIG. 4B, and implement mounting arms 407 can be locked in a desired position. Supports 427 mounted on machine frames 101 shown in FIG. 1A are built with a 3⁄4 slide bearing that allows shafts 414 to slide during side shifting, advantageously, providing additional support and rigidity to the system.
FIG. 4B shows 3 units 401 built into a 3 unit system 401/3 or alternatively a 2 unit system 401/2 (not shown) to perform 3 or alternatively 2 implement raising and lowering operations with down forcing and/or manual and/or motorized (not shown) side-shifting. The innovative side-shifting uses shafts 413 and 414 and linear slide bearings units 415 and 416 to allow the bolted assembly 411 to slide on shafts 413 and 414 at the top thereof via shaft fixing units 418 and 419 shown in FIGS. 4B and 4C, and shaft support 417 and 418 fixed on the machine frame thereabove. Accordingly, the assembly 411 can slide sideways, whereby implements can be moved sideways, according to job requirements, either manually or using a linear motor or other suitable motor system, and the like, by an operator and/or in an automated mode on autonomous machines.
FIG. 4C shows an example of a system, wherein the 3 piece assembly 411/3 of FIG. 4B is mounted on shafts 412 and 414, and forming the implement side-shifting system. The implement mounting arms 407 on FIG. 4A are replaced with implement mounted arms 420, 421 and 422, wherein various implements 426 can be side-shifted manually and/or in a motorized manner, and the like.
FIG. 5A shows side-shifting subsystem 501 as seen from seat 502 of the operator. In FIG. 5A, the seat and steering column can be adjusted, as indicated by dashed lines, so to provide a proper fit for the operator. Element 503 shows side-shifting of the seat 502 to assist operation by employing front railings 504 and rear railing 505 under the seat 502 in a manual or motorized manner. A chain, rope, indicator 507, and the like, hang down and can act as an operator assistor, wherein outside areas thereof implement a working area for the operator and raise the quality of work in progress.
FIG. 5B shows that the seat and steering column 502 can be placed in a forward driving mode for pushing the employed implements forward or in a rearward driving mode for applications employing the machine 100 as a tractor and/or for pulling various types of implements. Rectangular hollow tubes 506 are employed for fixing the seat and steering column 502 to the frame of the machine 100 towards a suitable direction based on a given application and/or job. Advantageously, the seat and steering column 502 can be easily replaced with suitable electronics, programs, antenna/receiver systems (e.g., VRS GPS/GLONASS/GALILEA, etc.), and the like, as described herein, so as to transform an operator driven system into autonomous, unmanned system at later date.
FIG. 6 shows the seat 502 with a steering column assembly 601, wherein examples of various steering column adjustments are shown. The steering column mounting 601 includes position adjustments and electronics and a tubular steering column support tube 602 for installing employed electrical wirings, and the like. Further shown are steering column box 603, and steering wheel 604 with touch screen 605 and/or smart phone interface for machine and implement operation and wireless communication. Areas 606 inside the center of the steering 604 can be used for placing various control buttons, selection buttons, and the like.
FIG. 7A illustrates automation provided by an implement ground tracing and implement lifting and lowering system. In FIG. 7A, examples are shown on implement 301 or 302 and implement lifting system 411, wherein operator assistor 507 shows an outer line of an implement working area, as shown in FIG. 5A. The system further includes swivel joint 410, as well as polished and tempered shaft 408, and linear slide bearing or ball bushing 409. Electronic height position controls 711 and 712 can be mounted directly on a shaft, and which provide implement lifting and lowering motor 402 the impulse to lift an implement via lifting arm 407 to a median level of shaft 408.
FIG. 7A further shows lifting arm 407 at a lowest position and being lowered to a mid position, and lifting arm 407 at a top position. The system allows for an automatic implement ground tracing system, and frees the operator to perform other actions or allows autonomous machines to work safely without harming the ground, turf, and the like. The lifting and lowering cables 705 and 706 are at rear ends of an implement. However, when wider range of lifting and lowering are employed, implement swinging during fast travel between jobs can be a problem, and steady down force of the mower unit can improve and maintain constant a mowing job.
FIG. 7B provides a solution for above and other problems. For example, a spring 713 placed inside lifting arm 407 can provide a constant pre-calculated down force on a front part of the implement. At the rear is provided a system including a cross bar 701 that travels along the lifting arm 407 up and down and pushed by rods 704 and 705. The cross bar 701 is pulled down by constant force springs 702, which the force thereof pulls down on rods 704 and 705 and in turn an implement, such as mower unit 301, and the like, with via the constant force of the springs 702. As the lifting and lowering range is increased, a linear motor 703 can be provided to raise the cross bar 701, advantageously, allowing the implements to raise up against soft lined stops 706. Accordingly, the above and problems are resolved, and such a system can be used in assisting in the sharpening of a mower unit mounted on a machine, for example, as shown in FIGS. 12A and 12B, as the mower units 301 can be raised higher above the ground, and the like.
FIG. 8 shows the multi-purpose design and applications of the vehicles and machines 100, and the like, including interchangeable features and designs used to advantageously achieve multi-purpose applications, and the like. The interchangeable lifting gear design 401/3 used for implements 301 and 302 can include installation in the front of the machine 100. The frame design tube 106 of the machines 100 can include a hollow square or rectangular tube around the machine frame to provide for implement mounting therearound, advantageously, expanding the multi-purpose application potential of the machine 100, and increasing the rate of machine utilization.
Alternative locations of electronic green speed measuring units 803 are shown, which provide impulse to lifting gears 401 and 402 to increase or reduce the roller implement force subjected on ground, and controlled by the force measuring devices 804 to achieve a pre-planned or pre-programmed green speed. Above the machine 100 there is an area 805, where more optional implements can be placed or mounted on rectangular or square tube 106 around the machine 100. This area can also be place for storing containers of liquids, and wherein the associated spreading or dispersing units can be placed under the machine 100.
Weed detectors 806 and green detectors 807 are shown, whereby requirements for fertilizers and weed controls can be programmed and mapped (e.g., via VRS GPS or GLONASS or GALILEA, etc.) in the computer programs of the machine 100 via antenna 115 and receiver 116 and/or systems 808. An example of the location of an implement outer work area is shown by operator assistor 507. Implement guidance system antenna/receiver 808 is shown, and which can also be used for mapping working areas into ICT-systems, and the like.
In FIG. 8, three turf improvement roller implements 801 and 802 are shown and further detailed in FIG. 15. FIG. 8 also shows an automatic clippings collection and dispersion system, including alternative locations of clippings containers, and unloading capabilities, as further detailed in FIGS. 10A-10B.
FIGS. 9A-9B illustrate an innovative reel mowing unit with electronic programmable cutting height and reel rotation speed control and automatic clippings collection and dispersion system to allow mowing of greens, fore-greens, collars, Tées, and the like, in an operator driven manner or for unmanned autonomous operation. In FIG. 9A and FIG. 9B, the frame of the mowing unit 901 is shown, wherein tooth bars 902 and tempered and polished corner shafts 903 form the cutting height adjustment slides, which are guided, for example, by 2 pieces per corner, linear ball bushings or linear slide bearings 904.
An example of the innovative design of the mowing unit attachment to implement lifting gear swivel joint 410 is shown in FIGS. 4 and 7, and which allow the free turning of the mowing unit for service, inspection and maintenance work, and where FIGS. 12A-12B show an innovative example thereof. An innovative cutting clearance adjustment 905, between the reel and a bottom blade is shown, and which allows a wide clearance opening by removing pin 906, wherein lever 907 moves to a fixed point 908 or two eccentric bolts 926 can be used, whereby opening is allowed. For example, as shown on FIGS. 9A-9B, the bottom blade sharpening of the reels 918 and bottom blade 910 can be performed, as further shown in FIGS. 12A-12B with an innovative sharpening unit fixed to a mowing unit.
Bottom blade holder 909 is fixed by 2 tempered bolts on frame 901 (e.g., one on each end), and bottom blade 910 is bolted thereunder. The cutting units can travel on the ground on round rollers 911. The height adjusted groomer 912 can be used to vertically-cut turf and groom to a pre-adjusted depth. The clippings collection conveyer tube 913 is open at a quarter on the top-side toward a reel rotation direction thereof, as part of the automatic clippings collection and dispersing system of FIGS. 10A-10B. Further provided are reel 916 of the reel cutting unit, interchangeable mounting plates 914, and bearing blocks 915. The plates 914 are accurately produced and metal pin guided and fixed (e.g., by bolts, etc.) on the frame 901, and when the reels are sharpened, the outside diameter is reduced, whereby the reel and bottom blade cutting angle can change. The end plates 914 can be replaced with new set of accurate end plates with suitable configurations, so that the reel center line can accurately change to achieve an ideal bottom blade and reel cutting angle, advantageously without time consuming and difficult manual adjustments, and the like.
In FIG. 9A, the cutting motor 916 powers the cutting reel. Also provided are pulleys 917 and belts 918. The toothed wheels 919 with matching teeth of tooth bars 902 can be used to accurately adjust the cutting height. Planetary gear 920 and motor 921 with brake and absolute encoder are used to power the cutting height adjustment system. In operation, the motor is only powered for the time of adjustment, and otherwise the brake locks the height to an adjusted level, and the absolute encoder shows numerically on a touch screen, and the like, the programmed height reached.
An alarm buzzer and light warning can be triggered, for example, if the programmed height has not been reached on the cutting units. The brake keeps energy from being used between adjustments, and keeps a pre-programmed cutting height constant, resulting in energy savings, quality of work, and the like.

The blade rotation can be controlled by electronic drive control, and the rotation of one blade can be reversed by using a gear 1122 mounted on toothed pulley 1106.
In FIG. 11B, using the two piece motor system, the electronic drive control can be used to prevent the blade tips from catching each other during rotation, and a direction of rotation can be programmed, wherein one of blades can be programmed in a reverse rotation mode. Various types of motors can be employed, for example, with a maximum rotation speed from about 5000 to 6000 RPM and above, so that a suitable blade tip speed can be reached for improving cutting quality, and the like.
Frame 1108 can include the programmable, electronically controlled cutting system for pre-programmed and accurate selection from the machine 100 operating system and/or autonomous machine operation (e.g., with a VRS GPS/GLOSSNAS/GALILEA operating system). Also provided are fine toothed shafts 1106, linear slide bearing or ball bushing 1107, and with gear 1109 having fine teeth to work with the shaft 1106, so as to move up and down to the pre-programmed cutting height selected from operating system. Servo motor 1110 is built with a brake and absolute encoder to perform cutting height adjustments accurately and in a locked in manner via the motor brake. Advantageously, power consumption is minimized to only the adjustment time in seconds, wherein the absolute encoder provides an indication that all the units have reached the selected height, shows the height in operating system display, and if not, can generate warning and/or buzzer sound, and the like. A planetary gear 1111 is used to increase a positional holding force, wherein toothed timing wheels 1112 and timing belts 1113 and 1114 are used for turning shafts 1115, which turn gears 1109 to perform the height adjustment. A level adjustment unit 1121 is used to level adjust the cutting height adjustment shafts 1106 and to eliminate backlash, advantageously, improving cutting height accuracy.
Also shown are right side gate 1116, left side gates 1117 and front 1119, and back side gate 1118, which can be lifted up manually or in a motorized fashion to direct the blown clippings towards a desired direction. When all gates are closed, the rotary mowing unit can be configured to mulch, bio-clip, and the like. The mowing unit lifting system further includes the swivel joint mounting 410 for the rotary mowing head with the shaft 408, the implement mounting 410, and the lifting arm 407. A locking ring and gear 1122 is employed to allow rotary cutting blade rotation direction to be reversed, providing for numerous applications and uses for the rotary cutting unit.
FIG. 12A is used to illustrate sharpening of the reel mowing units 301 via the implement lifting swivel joint 410 and the implement lifting and lowering gear 401. In FIG. 12A, the swivel joint 410 allows the mowing unit 310 to hang down in a vertical position. A reel cutting unit sharpening device 1201 is mounted on the reel cutting unit 301.

This system provides for an adjustable sharpening device travelling along linear bearing shafts 1208 and fixed with 2 piece twin shaft blocks 1209 on a sharpening machine frame 1210.
The sharpening machine frame 1210 is guided and bolted on the fixing lugs 925 of the reel mowing unit 301, as shown in FIG. 9B. Motorized linear grinding head transfer system 1212 moves the sharpening device at a programmed speed. The bottom blade adjustment 906 can be freed, and the arm can be locked into position 908, which allows sharpening and front facing of the bottom blade, rounding of the reel, sharpening of the reel blades to a specified angle, and the like. Alternatively, eccentric hardened pin bolts, and the like, can be used. The use of a locking ability or eccentric pin bolt, advantageously, allows the blade to be resting steady on the frame 1210.
The reel motor 916, as shown in FIG. 9A, turns the reel and transfer system 1212 not shown in detail, which operates the sharpening device to allow rounding of the reel, reel blade sharpening into a specified angle, bottom blade sharpening and front facing, and the like. Advantageously, the reel mowing units can be sharpened without removing them from the machine 100, resulting in more frequent sharpening, bottom blade facing, and the like, improving the quality of the cut.

The interchangeable system components can mounted on various interchangeable frame designs with suitable wheel pattern designs, and the like, for leaving an even wheel track surface without individual tire tracks, as well as improved weight distribution on a larger wheel print area and with less trampling of ground and need for aeration. The efficiency level from the battery pack to the wheels can reach up to about a 90% efficiency rating, and with zero emissions, as compared to a diesel engine vehicle, which from tank to wheels has a maximum efficiency of about 25%.
The mowing machines of FIGS. 1-15 can include:
Interchangeable machine frame designs, with only 3 frame sizes covering various mowing machine applications, including from 3 to 5 to 7 reel and rotary mowing configurations with a mowing width from about 51 to 138 inches.

The golf course maintenance and turf care machines of FIGS. 1-15 can include:
Performing about 30 or so additional and different jobs for golf course maintenance and turf care after the mowing and related jobs. Conventionally, each job requires a different, noisy combustion engine powered 3 to 4 wheel machine, carrying quite heavy loads and thus leaving wheel tracks on the turf. These machines can be replaced by the multi-purpose machine 100 having electric and battery powered operation, and which use interchangeable features from the mowing machine configurations, for example, including:
The 11 to 15 wheel, multipurpose machines 100, including the 11 wheel feeder and 15 wheel carrier machines having interchangeable drive systems and wheel patterns for leaving even turf marks and without wheel tracks due to reduced weight distribution, due to the large number of tires employed. This provides a vast tire print area, wherein the swiveling shaft designs keep all wheels on ground during travel over uneven surfaces and with even wheel load distribution.
The machines are designed for multi-purpose applications with an extensive range of implements.
The seed, fertilizer, pesticide, and the like, requirement and irrigations needs can be analyzed with suitable seekers or sensors attached to the mowing units, and with the data being transferred wirelessly to the information (e.g., ICT) system, and mapped with GPS for precision turf care. Advantageously, seeds, fertilizers, pesticides, and irrigation can be used only where actually needed and in the depth needed, without having excess materials flushing into the environment. This results in operating, investment and material cost savings, providing green, eco-friendly golf course and turf care. The described machines can be configured for any other suitable applications, and provide the platform for other types of applications and machines, as will be appreciated by those of ordinary skill in the relevant art(s) based on the teachings of the present disclosure.
The machines of FIGS. 1-15 in autonomous, unmanned, smart machine applications can include:
Addressing the need for cost savings in view of ever increasing labor costs, and the lack of professional workers. Companies must also find solutions to increase profitability, wherein increased revenues are important source. Golf courses loose revenues on busy seasons, when all the rounds cannot be cashed in due to the machines that are working during Tee-times. Conventional combustion engine machines cannot work overnight, as there are nearby houses and communities, which do not tolerate night time noise from such machines. Even the paying customers are annoyed by the machine noise during their games. The unmanned autonomous, silent precision golf course maintenance and turf care machines of FIGS. 1-15 can be the solution:
The operator driven machines 100 are designed to be retrofitted at a later time to operate as autonomous working machines, for example, using:
The VRS GPS/Glonass/Galilea, ICT-based systems, and the like, can be built with automatic steering and other operating systems to achieve unmanned, overnight, silent operating machines 100, whereby data for seeding, fertilizing, pesticides spreading, weed control and irrigation needs, and the like, are collected by the ICT-systems and used for precision turf care, with minimal materials employed.
The wireless remote diagnoses and combined operating and material data collections systems can be used to provide, for example, one invoice per month service. Agreement with long term leasing can be provided, whereby golf course revenues per an 18 hole course can increase in the hundreds of thousands per year and operating cost can be minimized.
Thus, the present invention is directed to a line of eco-friendly, cleantech and sustainable lawn maintenance machines and systems with aim to develop green golf courses, which is not reality today with current combustion engine and hydraulic machines, which use an excess of fertilizers and other vast variety of chemicals. The mowing and the increase of green speed can be performed on one go with the mower machines 100 using reel mowing units, a turf improvement roller system, and green speed measuring via the machine 100.
