More than just a preference, this choice is primarily based on your working conditions. In-furrow Designed for tractors with single wheels, in-furrow ploughs make ploughing easier. When positioned in the furrow, the tractor wheels provide good grip. By pressing against the bottom of the furrow, traction is at its best, especially in wet conditions. The tractor does not slip and you use less fuel. The furrow guides the tractor in a way that is very convenient if you do not have GPS navigation. On-land On-land mounted ploughs are generally recommended if your tractor is equipped with tracks, twin wheels or wheels over 710 mm wide. Some of our customers prefer on-land ploughing even though their tractor is equipped with single wheels so that they can use their GPS guidance system. By ploughing on-land, you will reduce tyre wear, especially if you have flinty soil. Choice of 2 systems to adjust working width: Multi-position or hydraulic vario width Which system should I choose? It’s quite simple, this is what you need to know... Multi-positions If your ploughing conditions do not vary significantly (plot contours, soil hardness, climate, crops, etc.), you do not need to change your working width frequently. In this situation, we recommend the multi-position system. When you need to change the working width of your plough, simply loosen the adjustment bolt and then position each plough body on the indicator for the width you want. The process takes just a few minutes. Hydraulic vario width If your plough is used by different people (for example, in a cooperative) or if you use your plough in different conditions (for example, subcontracting or on farms with different soils and crops), we recommend the Vario system. Using a hydraulic control valve in the tractor cab, you can adjust the working width to suit your needs. The bodies are always perfectly aligned. The Vario system is particularly useful for plots that have complicated shapes. A choice of 2 safety systems How should I choose, and which options should I include? Let’s look at what’s involved. Shear Bolt Continuous Hydraulics For stone-free soils, choose shear bolt safety. If the ploughing element hits an obstacle (stone, root...), the shear bolt snaps. The entire element rotates, rises and allows the foreign body to pass under the plough. The shearing noise alerts you, so you stop the tractor, get off and extract the bolt that gave way. You replace the shear bolt and you’re ready to plough again. For light and sandy soils without any stones, we recommend light soil shear bolts. The way it works is the same except there are 2 bolts for each ploughing element, one per body. Shear bolt safety extends the life of your equipment: it limits frame bending and it reduces the forces exerted on your tractor. Safety shear bolts give way when the body tip resistance exceeds between 4.2 and 6 tonnes. Compact, easy-to-handle, flexible.... The no-compromise, reversible mounted plough with the Grégoire Besson brand. Compact sizes With optimised lengths, the first body being as close as possible to the tractor and with body spacing starting at 90 cm, the overall size of Rover mounted ploughs is reduced. 1st Line Offset You can configure your 1st body to have a very large offset to reduce your working width and plough in areas that are difficult to work in. 3rd Point Suspension In order to protect your back and reduce impacts on the tractor chassis and plough, the coupling 3rd point can be connected to a hydraulic system that absorbs shocks. Hydraulic Switch All adjustments are made from the tractor cab even though there are only three double-acting spool valves. There is no need to have a large number of valves to benefit from all the plough’s functions. Robust Make a long-term, worthwhile investment. Choose Grégoire Besson for the right reasons. Robust Shafts The shaft is the heart of the plough. This is where the greatest number of forces are exerted. The bearings between the front axle and the shaft are distributed over a long length. This ensures good rigidity, optimal tightness, long-lasting turning and provides traction transfer. Double Frames Rover frames are extremely robust due to their thickness and tubular construction. By doubling them (welding 2 by 2), Grégoire Besson ensure that their frames give unbeatable longevity to your mounted plough. High-strength steel Our suppliers provide us with high-strength steels that are tested and verified. They strictly comply with our specifications which means you can be sure of robust components throughout the life of your plough. Finite Element Analysis The Grégoire Besson design office uses ’Finite Element Analysis’ (FEA) software. This means that high safety coefficients can be defined to guarantee optimal material resistance from the very beginning of the design. Smart Design We have been listening to farmers and designing ploughs since 1802. This experience speaks for itself. Protective Covers To protect hydraulic hoses and other vulnerable components, we fit protective covers on the headstock to minimize impacts and soil accumulation. The pressure gauges are still visible for reading from the cab. Independent Offset and Tilt Grégoire Besson’s parallelogram system enables you to make independent fine adjustments between the offset and the tilt. This allows you to adapt the plough to different tractor tracks, plough evenly on slopes and completely erase the first body line. Add or remove a body If you plan to change your tractor for one with higher or lower power, you can add or remove a body which means you continue to profit from your investment without having to change ploughs. Z-beam For more than 4 bodies, we offer Z-beam frames. The last body is positioned after the wheel which means there are no unworked areas. This improves the load transfer and makes the ploughing even more precise. Offset leg A simple design feature that makes the plough easy to pull and reduces fuel consumption. So, if you work 100 hectares per year, the offset leg will save you 150 litres of fuel. 2 types of vertical plumb adjustment Mechanical or hydraulic? It’s a simple choice. Mechanical vertical plumb Mechanical vertical plumb adjustment is ideal for in-furrow ploughing and for users who always plough at the same depth on uniform plots. If you want to align your plough with the tractor tilt in the furrow, simply insert or remove small metal shims in the vertical plumb adjusters and you are ready to go. Hydraulic vertical plumb Hydraulic vertical plumb adjustment is also recommended for in-furrow ploughing, and if your plough is used at different working depths. It corrects the plough’s vertical angle after the first pass which means it is easy to use. It also offers increased safety when attaching or detaching the Rover. Forward centre of gravity, easier lifting The Rover has a forward centre of gravity, close to the hitch and tractor. This makes the tractor easier to manœuvre and enables smooth lifting. It is still heavy enough for good penetration into loose or compacted soils. A wide choice of wheels RJR Wheel Back depth wheel Mechanical adjustment Tyres available: - 10.0 / 75 - 12 - 320 x 60 - 12 PS Wheel Lateral depth wheels Mechanical adjustments Tyres available: - 600 x 9 - 200/60 x 14.5 - 10.0/75 x 12 RT 10 Wheel Reinforced lateral depth wheel Mechanical adjustment Tyres available: - 13.0/55 x 16 - 11.5/80 x 15.3 RTT 10 Wheel Lateral depth wheel & transport Mechanical adjustment Tyres available: - 13.0/55 x 16 - 11.5/80 x 15.3 RLBM Wheel Lateral depth wheel and transport Hydraulic adjustment and realignment Tyres available: - 320 x 60 - 12 RLBH Wheel Lateral depth wheel and transport Hydraulic adjustment and realignment Tyres available: - 320 x 60 - 12 RTRH Wheel Lateral depth wheel and transport Hydraulic adjustment and realignment Tyres available: - 10.0 / 75 - 12 - 320 x 60 - 12 - 11.5 / 80 - 15.3 - 13 / 55 - 16 RCRH Wheel Lateral depth wheel and transport Hydraulic adjustment and realignment Tyres available: - 10.0 / 75 - 12 - 320 x 60 - 12 - 11.5 / 80 - 15.3 - 13 / 55 - 16 Which type of body should I choose? Your soil hardness will mainly determine whether you should take a body with bolt-on points or a body with bar points. We recommend bodies with bar points for soils that tend to become compacted or for grasslands. Body with bolt-on points Body with bar points Mouldboards available on bodies with bolt-on points Helico-cylindrical AR5H Mouldboard for moulded ploughing from 18 to 27 cm deep in all types of soil.

Skimmers, trash boards, disc coulters, etc. Mixed Skimmer The short coulter and mouldboard make this combination very versatile. It is suitable for 80% of applications. Plastic Mixed Skimmer The plastic mouldboard enables the surface to be scalped, even with very sticky soils. Universal Skimmer Its wider coulter and longer mouldboard enable this combination to handle larger volumes of plants than the mixed skimmer. Maize Skimmer The high mouldboard guarantees a smooth passage through tall plants such as corn, sunflower, etc. Pasture Skimmer The very long mouldboard enables it to turn over very dense root systems such as those found in grasslands. Trashboard Used mainly in winter ploughing, it positions the residues of large plants vertically to improve water infiltration. Spring-mounted Disc Coulter Suitable for stony soils. It cuts plants and soil 10 cm in front of the body. It creates a clean furrow base and wall that provides better grip to the tractor. Bolted Disc Coulter Suitable for lightly stony soils. It cuts plants and soil 10 cm in front of the body. It creates a clean furrow base and wall that provides better grip to the tractor. Knife coulter It cuts a strip of earth to stop the furrow wall attaching to the mouldboard and helps prevent it from crumbling. Mouldboard extension The mouldboard extension positions the earth for precise finishing. It limits wear at the end of the mouldboard. Spike Sub-soiler It loosens the soil to a depth of 15 cm under the plough body. It promotes water infiltration, gas exchange and root exploration. Furrow opener The furrow opener enlarges the furrow base so that track markers equipped with wide tyres have better grip. Andpak Self-aligning roller for consolidation You can add an Andpak roller on Rover 60, 70 and 80, regardless of the safety or working width management system you choose. This roller works like a front compactor, it self-aligns with the bodies and enables you to consolidate the soil. It delivers soil that is ready to be seeded in a single pass. It can also help you with self-seeding. It makes a significant contribution to seed germination by preserving soil moisture and limiting erosion. It can be integrated along the entire length of the plough and enables a stress-free first pass at the edge of the field. Our customers tell us Daniel, Belgium rover 50 « We bought it 4 years ago and its done about 1600 hectares. It’s like new. We’ve changed the points twice. What I like is the simplicity of the settings. We do everything when we start ploughing, but if we need to change a setting, we do it in the cab. » Jean-Claude, France rover 60 « We do a lot of subcontracting and we’re on our third Rover. The machine is reliable and durable. All the settings are centralized in the cabin. It is easy to use. We have a high work rate. Ploughing is increasingly requested by our customers. We have more and more customers who do organic farming. » Bartosz, Poland Rover 70 « We use it on our 2,000 hectare farm. We chose hydraulic safety because we have a lot of stones in the fields. It triggers quite often. If we had taken the shear bolt safety, we would never stop replacing them. It is a reliable machine. » A look around your machine...
