Belt tension adjustment
To adjust the tension do the following (see fig. 21):
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.
