3. To check the adjustment, slowly squeeze the control
bar towards the handle. The cable is adjusted
correctly when resistance is felt when the control bar
is approximately 1” (25mm) from the upper handle
(Fig. 025).
To remove the transmission from the mower proceed as
follows:
1. Remove both rear wheels.
2. Remove the retaining rings, springs, gears, keys,
clutches, and pivot arms on both sides (“Wheel
Pinion Clutch” on page 5-2).
3. Remove the belt.
4. There is a suspension bracket on each side that
secures the transmission and pivot arms to the
chassis. Each bracket has 2 screws. Once they are
removed, the transmission will drop out.
To install, reverse the above process.
Fill the transmission level with the ll plug opening after it
is installed in the chassis. The top of the transmission is
not sealed, so it may leak if lled and tipped.
