Challenger’s exclusive Steerable Three-Point Hitch was presented as a technical innovation at the Italian EIMA International machinery show, in Bologna.
Optionally available on all Challenger MT800E series models, including the flagship MT875E, the new steerable hitch design improves turning performance under load and allows the operator to manage how the implement trails the tractor in tillage and row crop applications.
Pivoting on the differential rear axle housing, the new geometry allows for 118mm steering cylinder travel, resulting in more precise control of the hitch lateral position. In addition, steering cylinders now connect at a distance of 389mm (219mm on C-Series models) from the pivot point, boosting the steering torque by 20 per cent compared to C-Series models.
The two operating modes are set using the TMC Display. The Manual mode provides for a fixed steering position. The Float mode provides dampening of implement movements and offset draft reduction.
Providing excellent manoeuvrability for better field contour following, benefits include reduced machine stress by dampening implement lateral shocks, a 25 per cent reduction in turning radius with mounted implements, while the reduction in the power necessary for steering the implement helps to reduce slippage by up to five per cent.
Challenger’s product marketing manager for tracked and articulated tractors, Luca Cattani, said the Steerable Three-Point Hitch option was popular in all markets from South Africa to Central Europe where customers understood and favoured the company’s competitive advantage in applying 100 per cent power to the ground.
