Abstract: 107,083. Sackett, C. E. June 28, 1916. Ploughs; cultivators; manure and seed distributors; rollers, land.-A machine for ploughing, pulverizing, manuring, and levelling soil and for sowing seed in the treated soil comprises a motor-driven tractor, supported on a traction roller 4 and a steering roller 5, carrying a lateral extension on which are mounted four plough beam guides 6, 7, 8, 9, a pulverizing wheel 13 and a seeding device 57 provided with soil-levelling rollers 71, 72. Plough beams 10, 11 carrying a pilot plough 12 and skim and main ploughs 30, 29 respectively slide in the pairs of guides 6, 7 and 8, 9, their weights being balanced by counterweights 23, 39 to which they are connected by cables passing over pulleys mounted on the frame. The depth of furrow of the plough 12 is controlled by an adjustable stop arranged on the plough beam guides. In the operation of the machine, the first furrow is cut by the plough 12 after which it becomes a furrowclearing plough moving along the furrow last made to clear it of any soil that may have fallen back, thus giving a clear path for the pulverizing-wheel 13 which is provided with internal teeth 103, and into which the soil is turned by the main plough 29. The skim plough 30 throws a thin cut of sod, weeds, or turf into the furrow behind the plough 12 in front of the wheel 13 which rolls it into the bed of the furrow. The plough beams are lifted by links and bell-crank levers connected to handlevers arranged near the operator's seat. A shaft 40 pivoted at the front of the machine and connected with the steering roller 5 carries a number of rollers 44 adapted to roll down weeds and stubble. Disk cutters 45 are arranged on the sides of the rollers at approximately furrow widths apart. These cutters are raised for turning and travelling by links 151, 151' and bell-crank levers 52, 53 connected by a link 54 to a hand-lever 55. The weight of the cutters is balanced by a counterbalance 56. The steering connexion between the shaft 40 and the steering roller 5 is automatically disconnected when the cutters are raised. Seed passes from the device 57 through distributing mechanism which delivers it in fixed quantity through dropping tubes 60 which telescope into seed planting tubes adjustably arranged in a lower movable section of the planting device. One to four tubes to a furrow may be used. The depth of sowing is regulated by adjusting screws for the frame carrying the seed planting tubes. The seed-distributing mechanism is adapted to be clutched to the motor shaft and the speed of seed delivery may be varied by a series of change gears. The roller 71, before the sowing device, rolls the soil to a fixed level and the roller 72 at the rear of the device rolls back the disturbed soil. The weight of the vertically movable part of the device is balanced by a weight 78. An indicator connected to the roller 5 indicates if the machine is travelling in a straight line. Fertilizer may be discharged from a suitable receptacle upon the weeds at the bottom of the furrow in front of the pulverizing wheel, within the wheel upon the soil being pulverized, or behind the wheel upon the falling earth. The internal teeth 103 of the pulverizing wheel are mounted upon cross bars adjustable around the rirn of the wheel. The wheel is mounted in swing-bars 97 pivoted to the main frame to allow independent vertical movement.
