Belt tension adjustment
To adjust the tension do the following
(see fig. 22)
:
1. Remove belt shields. Clean foreign material from the mower deck and belt area.
2. Loosen the four nuts holding the gearbox support plate to the central plate.
3. Loosen the two blocking nuts on the adjustment bolt.
4. Turn the adjustment bolt clockwise until the proper belt tension is reached. This will
draw the gearbox support plate to the rear, thus tightening the belts.
5. Tighten the two blocking nuts on the adjustment bolt.
6. Retighten the four nuts holding the gearbox support to the central plate.
7. Reinstall the belt shields.
4.05 - Belt Replacement
If the belts have been stretched or damaged to the point where the proper tension
cannot be obtained they must be changed.
IMPORTANT:
When replacing belts always remember to replace both belts at the same
time. Replacing belt on only one side of the mower deck will cause unnecessary belt
slippage and premature belt failure.
To replace belts do the following:
1. Remove belt shields. Clean foreign material from the mower deck and belt area.
2. Loosen the four nuts holding the gearbox support plate to the central plate.
3. Loosen the two blocking nuts on the adjustment bolt.
4. Turn the adjustment bolt counter clockwise, pushing the gearbox support plate
forward until all tension is released
(see fig. 22)
.
5. Loosen rear nuts holding central plate (do not remove them).
6. Remove front nuts holding central plate.
7. Lift the front of the central plate and remove old belts.
8. Replace new belts
(see fig. 23)
. Loop the first belt over the left spindle and around
the lower groove of the center spindle pulley and the lower groove of the gearbox
