All new 3m wheelbase Mobil-trac track units provide a light footprint, while also ensuring the tractor’s power is effectively transferred to the ground. Tracks also provide improved traction, flotation and reduced compaction compared with wheels. The exclusive Opti-Ride track suspension system improves comfort and helps the tracks follow ground contours.

All the tractors feature 16/4-powershift transmissions that transmit full power in every gear. A range of automatic gear shifting methods allow operators to select the correct mode to maintain peak tractor performance.

A supremely comfortable, air-conditioned cab helps ensure operators can get the best from these high performance workhorses. All the main tractor operations are monitored and controlled via the comprehensive Tractor Management Centre (TMC). The screen on the TMC can set display one of 16 different functions.

Productivity is further enhanced with the optional Auto-Guide satellite navigation system. This highly accurate system automatically steers the tractor in parallel tracks across the field.

Another option is a steerable three-point linkage. Providing 12º of movement to either side, the system allows the tractor to make in-field steering correction more easily. Hitch lift capacity is an enormous 8,845kg.
