Heavy-Duty Components for an Increased Machine Life

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.

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.

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.



Well Formed Plowing with Moldboard Choices

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® Share Points
Reversible for maximum efficiency. More pronounced shape 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

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.

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.

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.
