Checking the Transaxle Oil
1. Park the machine on a level surface.
2. Disengage the PTO, set the parking brake, lower the
attachment lift, stop the engine, and remove the
ignition key.
3. Tilt the seat up.
4. Clean around the transmission dipstick (Fig. 46) so dirt
cannot fall into the filler hole and damage the
transaxle.

1. Transmission dipstick and filler tube
5. Pull out the transmission dipstick and wipe the metal
end clean (Fig. 46).
6. Slide the dipstick fully into the filler tube (Fig. 46).
7. Pull the dipstick out and look at the metal end (Fig.

When the transaxle is cold, oil should be in the
operating range, below the full line on the dipstick.

10W-30 detergent oil into the filler tube to raise the
level to the full line.

ignition key.
