Drive System
Maintenance
Checking the Transmission
Fluid Level
The transmission is filled at the factory with
approximately 94 fluid ounces of Mobil Dexron
lll automatic transmission fluid. Check fluid level
before the engine is first started and every 50
hours thereafter.
Note:
The seals used in the transmission are
internally lubricated with grease. During initial
operation of mower, slight weeping of grease from
these seals will occur. Wipe off excess grease.
Important:
Use only Mobil Dexron lll or
equivalent transmission fluids. Other fluids
could cause system damage.
1. Place the mower on its drums on a level
surface.
2. Remove the check/fill plug from the right-hand
side of the transmission (Figure 29).
The oil level should come to the bottom of
the fill hole. If it does not, add enough of
the proper oil type until the level reaches the
bottom of the fill hole.
