Four Wheel Drive (Orange) (Optional)

IMPORTANT: To prevent damage to the hydrostatic system, do not switch four wheel drive ON or OFF while driving combine in third gear (road gear) at maximum travel speed. Reduce speed to less than 1/2 of maximum.

Turn four wheel drive OFF before going down a steep grade.

When driving combine in conditions which cause high pressures in the hydrostatic system and the combine slows down or stops, move multifunction control handle to neutral and shift transmission to a lower gear.

It is ok to switch between low (turtle) and high (rabbit) settings on the "GO" while harvesting.

Two speed four wheel drive is controlled by switches (A). Press either switch once to turn ON or once to turn OFF. Light indicator (B) above either switch will turn ON when system is activated.

Press bottom switch (turtle) when more traction is needed or top switch (rabbit) when higher speeds are required.

causym CAUTION: Ground speed will increase when system is turned OFF and decrease when turned ON.

NOTE: For best performance, it is recommended that the two speed four wheel drive be left in low (turtle) speed. This allows the machine to operate at maximum torque capacity. It is recommended to use high (rabbit) speed only to allow rear wheels to spin out faster than ground speed when required.

It is normal for front wheels to spin out (lose traction) before the rear wheels in most conditions. In extremely muddy conditions, it may be necessary to apply both brakes momentarily to increase hydrostatic pressure to the four wheel drive motors. If rear wheels spin excessively, shift from 2nd gear to 1st gear.

    Approximate ground speed reduction:

  • First Gear: 20%
  • Second Gear: 30%
  • Third Gear: 50%
