2. Remove the filler and test level plug. (See the figure for plug location.)
3. Add oil through the filler plug until it starts running out of the test plug. (Pour oil slowly to make
sure that the lower portion of the gearbox housing has been filled.)
4. Screw the test and filler plugs back into their corresponding places.
It is recommended that the oil level plug be removed after every 8-10 hours of operation and oil added
until it runs out of the test plug hole. The filler plug hole and test plug hole are both located on the
back of side of the gearbox.
Note:
1. Do not overfill the gearbox with oil. This will result in pressure build-up inside the unit, which can
cause the oil seals to leak.
2. If the gearbox suddenly begins making an unusual noise, stop at once, check for oil leaks, and
refill it as required.
Driveline Lubrication
Grease fittings are located on the cross and bearing kit assemblies of both U-joints. U-joints should be
greased after every 8 hours of operation. See the figure below for the location of the grease fittings.
Do not force grease through the needle bearing cup assemblies.
The metal telescoping drive tubes inside the plastic shield tubes must be lubricated before each use.
(See the figure on the following page.)
Disconnect the driveline from the tractor and pull the halves apart. (Do not disconnect the driveline
that is attached to the mower gearbox.) Insert grease into the drive tube and spread it evenly.
Reconnect the two driveline halves together. Reconnect the driveline to the tractor’s PTO and raise
and lower the mower several times so that the grease just applied spreads over the entire working
area of the drive tubes.
