Using the KUHN Vari-Leader plow, operators will benefit from a number of 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 reduces pulling power requirements, provides good bearing capacity and allows for operation in difficult end-of-season conditions.

Your benefits

Heavy-Duty Components for an Increased Machine Life

Traction_Bolt.jpg

Traction Bolt

A clean break of the traction bolt, following a force of 5,280 – 8,820 pounds at the plow point, avoids the risk of nuisance shearing. The traction bolt system is economical safety system that avoids the wear associated with shear bolt systems.

Non-Stop Hydraulic (NSH) Reset

When a field obstacle is met, a rapid breakaway of the plow leg occurs. Once the obstacle is passed there is an increase in pressure, bringing the bottom quickly and firmly back into working position. The system also acts as a shock absorber in rocky ground, increasing plow life.

Headstock and Frame

For added reliability, the structure is made using a large, machine-welded frame measuring approximately 7” x 7”.

Triplex Steel

Moldboards are made of unequal layer, heat-treated Triplex steel that have an increased working life up to 40% over standard steel and a hard wearing surface over 1/8” thick.

Moldboard Choices to Match Your Needs

H4_Moldboard.png

H4 Moldboard

The H4, helicoidal, Scandinavian-type moldboard provides well-formed plowing to a normal depth range of 7-12”. The share is fitted with a reversible/replaceable point that greatly increases the life of the share. Recommended for fall plowing, the H4 moldboard is especially suited for heavy and damp clays. Furrow passes are well defined and trash burial is excellent.

N Moldboard

The helico-cylindrical N moldboard plows to a depth of 14”. Designed to be highly versatile, it is cylindrical at front, helicoidal at rear. A low draft ensures a partly broken furrow with excellent trash burial. Recommended for spring plowing, this moldboard is versatile and works well in sandy or clay soils.

Olympic®

Reversible for maximum efficiency. More pronounced form at wearing zones on the point for longer life and better protection of the landside. Point is self-sharpening for good ground penetration of at all times.

Enhance Your Productivity in the Field

Vari-Leader_Action_02.jpg

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 the tractor 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 fewer hydraulic valves to operate on headlands. Hydraulic sequencing also allows for automatic folding of the offset when the plow is being lifted.

Skimmer

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.

1.     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.

2.     Up and down-rapid and precise height adjustments (8” of adjustment) with countersunk holes in the skimmer leg for easy locking of the leg for the desired height.

3.     Side to side-for correct adjustment in relation to the disc coulter (where fitted).

  • Peter Hendriks testimonial KUHN
    Peter Hendriks Listowel, Ontario, Canada

    “I’m happy with the plow (KUHN Vari-Leader Semi-Mounted Rollover Plow) and our neighbors are saying it did a good job for them too. They are really impressed with the little tractor pulling the plow in such heavy ground.”
