The cutting width of Kuhn Vari-Leader - 7 body plows can be adjusted on-the-go from the cab. This is beneficial for plowing in smaller or non-square fields and different soil types.
Benefit from a number of improved features including reinforced box sections, rapid adjustment of furrow widths and superior protection systems. Working right up to the edge of the field is necessary to get the most out of your cropland, while limiting weed development. To meet this requirement, Kuhn has integrated the wheel extremely close to the frame due to its shape. An extra-large wheel is necessary to reduce the traction requirement, provide good bearing capacity and for operation in difficult end-of-season conditions.
On-Land Offset
On-land offset is available to enhance productivity. The soil sometimes requires wide or dual tires that cannot be used for in-furrow plowing. If the tractor is setup for other applications that require duals or wide tires, if equipped with the on-land kit it is no longer necessary to dismount the wheels in order to use if for plowing.
Hydraulic Valves
Hydraulic sequencing comes standard meaning fewer valves to operate during headland turns. Ease of use is always important when handling large machinery. With this system, there are less hydraulic valves to operate on headlands. Hydraulic sequencing also allows for automatic folding of the offset when the plow is being lifted.
Structure
For added reliability, the structure is made using a large, machine-welded frame measuring approximately 7”x7”. A stub axle mounted on tapered roller bearings makes this turning system incredibly reliable. With two telescopic, single-acting cylinders, headland turns are jolt free. This also reduces stress on the tractor’s lift arms allowing for optimum comfort during progressive turns. For more stability in transport, as well as frame protection during road travel, the lifting cylinder is equipped with hydro-pneumatic suspension.
Skimmers
Each skimmer is independent of another and firmly held in a sheath-like support. The skimmers are shear bolt protected and are adjustable in three directions. Forward and backward—with a choice of three positions, the sheath bolts to the leg support via countersunk holes to avoid any risk of free play. Up and down—rapid and precise height adjustments (8” of adjust/p>
Moldboards
Moldboards are made of unequal layer, heat-treated Triplex® steel that have an increased working life up to 40% and a hard wearing surface over 1/8” thick. Forged with a force of 6,000 tons ensuring excellent wear resistance and self-sharpening profile due to the grain in the steel resulting from the forging process. Depending on the soil type, Kuhn offers three different types of moldboards. The H4 moldboard is recommended for fall plowing, as it is suited for heavy and damp clays. The N moldboard is recommended for spring plowing because it is versatile and works well in sandy or clay soils. The VP slatted moldboard is designed for use in extremely sticky muck and clay soils, but is not for us in soils with rocks or stones.
