WARNING

To prevent serious injury or death:

•

Always shut tractor down using “Tractor Shutdown

Procedure” provided in this manual before servicing,

adjusting, cleaning, or maintaining this implement.

Replace belts when necessary. When replacing belts,

first loosen the belt tension to permit removal of the belts

themselves.
1. Remove fastener bolts, associated washers, and belt

cover.

2. Loosen jamb nut (#1) securing thrust rod (#3) and

adjusting nut (#2).

3. Loosen the pressure on tensioner roller (#4) by

turning adjusting nut (#2).

4. Remove belts (#5).
5. Fit new belts (#5) on pulleys (#6 & #7) as shown.
6. Turn adjusting nut (#2) to bring the tension roller (#4)

back into contact with the belts (#5) and to set the

belts to the correct tension. Refer to

“Check Belt

Tension”

on page 47.

IMPORTANT:

Measure the tension of all the belts if

possible and calculate the average value.

IMPORTANT:

To maintain uniform belt tension, the

belts must always be replaced together as a set and

never individually.

Figure 4-3

Tighten the jamb nut to the correct torque.

8. Install belt cover, washers, and bolts onto the

transmission housing. Tighten the bolts to the correct

torque.
