Transaxle (Transmission) Fluid Change
This transaxle is designed with an external fi lter for
ease of maintenance. To ensure constant fl uid quality
levels and longer life, an oil fi lter change interval of
every 200 hours is recommended.
The following procedure is performed with the
transaxles installed in the mower and the mower on
level ground. Apply the pump release valve for each
transaxle and set the parking brake.
1. Remove the three ¼" fi lter guard screws and fi lter
guard. Clean any loose debris from around the
perimeter of the fi lter. See illustration.
2. Place an oil drain pan (12" or more diameter and
8 qt. capacity is optimal) beneath the oil fi lter.
Remove the oil fi lter from the transaxle.
3. After the oil has drained, wipe the fi lter base
surface and apply a fi lm of new oil to the gasket of
the replacement fi lter.
4. Install the new fi lter by hand, turning it three-
quarters to one full turn after the fi lter gasket
contacts the fi lter base surface.
5. Reinstall the fi lter guard. Torque screws to
65 in/lbs. each.
6. Repeat steps on the opposite side.
7. Drain old oil fi lters of all free fl owing oil prior to
disposal. Place used oil in appropriate containers
and dispose of it in accordance with laws in your
area.
8. Remove the top port plug (see illustration) from
the left side and right side of the transaxles prior to
fi lling with oil. This will allow the transaxles to vent
during oil fi ll.
9. Remove the cap from the transaxles' expansion
tank located on the vehicle frame.
10. Fill with 20W50 motor oil until oil just appears
at the bottom of each transaxles' top port
(approximately 2 quarts per transaxle, 4 quarts
total). Install the top port lug into each transaxle as
the oil level reaches the port.
11. Install and torque the top port plugs to 180 in./lbs.
12. Continue to fi ll the transaxles through the
expansion tank until the "Full Cold" line is reached
(this will take approximately 23 additional ounces).
13. Reinstall the expansion tank cap by hand. Be
careful to not overtighten.
14. Proceed to the purge procedure.
