FRONT-WHEEL DRIVE
FRONT AXLE DIFFERENTIAL/FINAL
REDUCTION GEAR CASE
Checking the Front Axle Differential/Final
Reduction Gear Case Oil Levels
NOTE: Check the oil level in the combined front
axle differential/final reduction gear case after
every 50 hours of operation.
1. With the tractor standing level and the
engine off, check the front axle oil level using
the dipstick/filler plug ①.
2. The oil is at the correct level when it reads
between the 'full' mark and the lower end of
the dipstick. If the oil level is low, add SAE
80 hydraulic oil through the combined
dipstick/filler opening. Do not fill beyond the
dipstick 'full' mark, or the front axle will be
overfilled.
NOTE: To obtain the correct oil level reading, do
not screw the dipstick into the axle case, when
checking the oil level.
3. Reinstall the dipstick/filler plug.
Changing the Front Axle Differential/Final
Reduction Gear Case Oil
NOTE: The oil in the combined front axle
differential/final reduction gear case should be
changed after every 300 operating hours.
1. Place a suitable container beneath the oil
drain plugs ① located at the bottom of the
final reduction gear housings on both sides
of the tractor.
NOTE: The capacity of the combined front axle
differential/final reduction gear case is 2.0L of
hydraulic oil.
2. With the oil at normal operating temperature,
remove the dipstick/filler plug ② and both
drain plugs and allow the front axle case to
completely drain.
