5. Push the tension wheel toward the rear of the unit to
move the fork tube against the frame (Fig. 36). (If it
does not touch the frame, continue turning the
tensioning screw until it does.)
6. Begin removing the track at the top of the tension
wheel, peeling it off of the wheel while rotating the
track forwards.
7. When the track is off of the tension wheel, remove it
from the drive sprocket and road wheels (Fig. 36).
8. Beginning at the drive sprocket, coil the new track
around the sprocket, ensuring that the lugs on the track
fit between the spacers on the sprocket (Fig. 36).
9. Push the track under and between the road wheels
(Fig. 36).
10. Starting at the bottom of the tension wheel, install the
track around the wheel by rotating the track rearward
while pushing the lugs into the wheel.
11. Turn the tensioning screw counter-clockwise until the
distance between the tension nut and the back of the
fork tube (Fig. 34) is 2 3/4 in. (7 cm.).
12. Align the closest notch in the tension screw to the
locking bolt hole and secure the screw with the locking
bolt and nut.
13. Lower the traction unit to the ground.
14. Repeat steps 2 through 14 to replace the other track.
Replacing the Tracks (TX 425, Model
22307)
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 three to four inches (7.6 to 10 cm.) off of
the ground.
3. Remove the locking bolt and nut (Fig. 35).
4. Using a 1/2 in. drive socket, release the drive tension
by turning the tensioning screw clockwise (Fig. 35
and 37).

5. Push the tension wheel toward the rear of the unit to
move the tension tube against the frame (Fig. 37). (If it
does not touch the frame, continue turning the
tensioning screw until it does.)
6. Remove the nut securing the outer tension wheel and
remove the wheel (Fig. 37).
7. Remove the track (Fig. 37).
8. Install the new track, ensuring that the lugs in the track
fit between the spacers in the middle of the drive
sprocket (Fig. 37).
9. Install the outer tension wheel and secure it with the
nut (Fig. 37).
10. Torque the tension wheel nut to 220 ft.-lb. (298 N⋅m).
11. Turn the tensioning screw counter-clockwise until the
distance between the tension nut and the back of the
tension tube (Fig. 34) is 2-3/4 in. (7 cm.).
12. Align the closest notch in the tension screw to the
locking bolt hole and secure the screw with the locking
bolt and nut.
13. Repeat steps 2 through 12 to replace the other track.
