Heavy-Duty Components for an Increased Machine Life

Kuhn Vari Challenger Series NSH System

Non-Stop Hydraulic (NSH) reset comes standard and protects the points, shares and other critical components from damage by rocks or foreign objects. The NSH system allows each individual bottom to move up to 27.5” vertically and nearly 8 inches laterally.

Triplex logo 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.

Kuhn Vari Challenger Series Strong Backbone

Strength and durability starts with a strong backbone. In this case, the main beam measures a stout 8.7” by 8.7”. Many of the moving parts have been integrated into the machine’s structure to safeguard against impact, humidity and dust.


Well Formed Plowing with Moldboard Choices

Kuhn Vari Challenger Series 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.

Kuhn Vari Challenger Series 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.

Kuhn Vari Challenger Series Olympic® Share Points

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 at all times.

Enhance Your Productivity in the Field

Kuhn Vari Challenger Series Hydraulically Adjustable Plowing Width

Users can easily adjust the plowing width from the tractor cab. The furrow can be narrowed to 14” for deep plowing and/or heavy soils. Increasing the furrow width to up to 22” improves productivity when working at shallower depths in lighter soil conditions.

Kuhn Vari Challenger Series On-Land Hitch

The Vari-Challenger includes an on-land hitch as standard equipment to accommodate large tractors with dual wheels. An available offset hitch kit offers even further clearance for extra-wide tires. Tracked tractors will especially benefit from the optional front mounted undercarriage, as it reduces the weight on the tractor for improved traction and handling. If the conditions require it, the plow can also be converted to an in-furrow machine.

  Kuhn Vari Challenger Series Rear Body Lift

Hydraulic lift allows for progressive furrow entry by angling the main beam. This creates a smoother and more even headland and lowers fuel consumption. The rear section (behind the transport wheels) can be lifted out of the ground completely so only the front section is plowing, reducing power requirements in extremely difficult soil conditions.
