WARNING: When washing the mower, direct the spray away (especially if using a power washer)
from the Hydro-Gear ZT 2800 transaxle’s seals to prevent water intrusion and to ensure component
performance.
WARNING: Make sure the transaxles are cool before performing service procedures.
Fluid changing procedure
1. Park the unit on a level surface. Place control levers in the park brake position, disengage deck clutch, remove igni-
tion switch key and disconnect negative battery cable.
2. Remove the three 1/4” filter guard screws and filter guard. Clean any loose debris from around the filter (FIG. 42).
3. Place an oil drain pan beneath the oil filter and remove the oil filter from the transaxle. By removing the filter, this
also drains the system oil.
4. After the oil has been drained, wipe the filter base surface off and apply a film of new oil to the gasket of the new
replacement filter.
5. Install the new filter by hand, turn 3/4 to one full turn after the filter gasket contacts the filter base surface.
6. Re-install the filter guard with three 1/4” screws. Torque the screws to 65 in.-lbs. each.
7. Repeat steps 2 - 6 for the opposite side transaxle.
8. Drain oil filters of all free flowing oil prior to disposal. Place used oil in appropriate containers.
9. Remove the top port plug from the left side and right side transaxles prior to filling with oil. This will allow the
transaxles to vent during oil fill.
10.Remove the cap from the transaxle's expansion tank.
11. Fill oil reservoir with 20W-50 motor oil until oil just appears at the bottom of each transaxle’s top port (approxi-
mately 2 qts. per transaxle, 4 qts. total). Install the top port plug into each transaxle as the oil level reaches this
port.
12.nstall and torque the top port plugs to 180 in. lbs.
