Transportation 9980 Self-Propelled Peanut Combine
Four-Wheel Drive
Read First
It is not necessary to engage the four-wheel
drive except for additional traction in muddy
conditions.
Remember the following when using four-
wheel drive:
•
It is NORMAL for front wheels to lose
traction and spin before the rear wheels in
most conditions. When this occurs, shift
the transmission from first gear to second
gear.
•
In very muddy conditions, it may be
necessary to apply both brakes
momentarily to increase hydrostatic
pressure to the four-wheel drive motors.
•
If rear wheels are spinning excessively,
shift from second gear to first gear.
•
To prevent damage to the hydrostatic
system, do NOT switch four-wheel drive on
or off while driving the combine in third
gear (road gear) at maximum speed.
•
In third gear, the hydrostatic control lever
should be moved below number “4” on the
decal before switching four-wheel drive on
or off.
• Turn four-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 pressure in
the hydrostatic system.
