Replacing the Tracks (Model 22324)
When the tracks are badly worn, replace them.
1. Lower the loader arms, stop the engine, and remove
the key.
2. Lift/support the side of the unit to be worked on
so that the track is 3 to 4 inches (7.6 to 10 cm) off
of the ground.
3. Remove the locking bolt and nut (Figure 44).
4. Using a 1/2 inch drive socket, release the drive
tension by turning the tensioning screw clockwise
(Figure 44 and Figure 46).

track fit between the spacers in the middle of the
drive sprocket (Figure 46).
