To avoid personal injury:
A
Be sure to stop the engine and remove the key
before changing or checking the oil.

Allow transmission case to cool down
sufficiently; oil can be hot and may cause
burns.
The fluid in the transmission case is also used for the
hydrostatic drive system.
1. To drain the transmission oil, place oil pan underneath
the transmission case and the rear axle gear case
(RH&LH) and remove the drain plug at the bottom of
the transmission case and the rear axle gear case
(RH&LH).
2. After draining, reinstall the drain plugs.
3. Fill with UDT or SUPER UDT hydrostatic transmission
fluid or its equivalent up to the upper line of the gauge.

It takes time to have the oil poured from the
transmission case reach the rear axle case (RH&LH).
Pour the regulated amount of oil slowly.
4. After running the engine for a few minutes, stop it and
check the oil level again; add oil to the prescribed
level.
