Changing the Transmission, Rear Axle, and
Hydraulic System Oil
NOTE: Change the transmission, rear axle, and
hydraulic system oil after every 300 hours of
operation.
NOTE: During cold weather operation, tractor
hydraulic oil can be changed to ISO VG 46 oil is
a multiviscosity oil which has improved flow
characteristics in low temperatures and can be
used year round.
1. Place a suitable container beneath the
transmission and rear axle drain plug to
catch the used oil. (Note that the combined
reservoir holds 13L of oil.) With the oil at
normal operating temperature, drain the
system by removing the transmission and
rear axle drain plug ① and the filler plug ②.
Reinstall the drain plug after all of the oil has
drained out. Discard the used oil properly.
2. Add ISO VG 46 hydraulic oil at the filler hole,
②. The transmission is filled to the correct
level when the oil registers between the two
marks on the dipstick ③. Do NOT fill above
the dipstick full mark. Capacity for the H.S.T.
reservoir is 13L.
3. Reinstall the dipstick and filler plug.
IMPORTANT: There is a common sump for the
transmission, rear axle, and hydraulic system.
Therefore, extra care should be taken to keep
the oil clean.
