Four-Wheel Drive

IMPORTANT: To prevent damage to the hydrostatic system, do not switch 4-Wheel Drive (A) on or off while driving combine in third gear (road gear) at maximum travel speed.

Turn 4-wheel drive off before going down a steep grade.

Driving the combine in heavy load conditions that cause the combine to slow down or stop can cause high pressures in the hydrostatic system.

NOTE: The road safety switch must be in the field (off-road) position before four-wheel drive can be engaged.

To engage the 4-wheel drive press switch (A).

The 4-wheel drive system is designed for use in conditions where traction is poor or when needed to improve steering control.

It is not necessary to engage 4-wheel drive when driving the combine harvester unless conditions are soft or muddy.

In most conditions, it is normal for front wheels to spin before rear wheels spin. When this occurs, shift into 3rd gear. In extremely muddy conditions, it may be necessary to apply both brakes momentarily to increase hydrostatic pressure.

If rear wheels are spinning excessively, shift from second to first gear.
