the caster arm (refer to the Height-of-cut Chart, page 25).

remove the key.
2. Wait for all moving parts to stop before leaving the
operating position and then chock or block tires.
3. Place a jack under the rear center of the engine frame.
Raise the back end of the engine frame up enough to
remove the drive wheels.
4. Remove the drive wheels.
5. Loosen, but do not remove, the 2 axle pivot bolts
(Fig. 26).
6. Remove the 2 axle adjustment bolts (Fig. 26).
