To sharpen blades, first remove them following the above instructions. Place the blade
in a vise and sharpen them by using a hand file or grinder.
Do not sharpen the blades
to a sharp cutting edge.
The cutting edge should be between 0.5 to 0.6 mm. (
1
/
64
" to

") to prevent excessive pitting and dulling of the blades. Sharpen both ends of the
blade equally for balance and always maintain corners. Always keep all three blades
sharpened equally in order to maintain balance.
CAUTION: unbalanced or warped blades can cause damage to the mower and/or
personal injury. Replace damaged blades before operating the mower. Sharpen
both ends of the mower blades equally or until the blade is balanced.

Belt tension control

Belt tension adjustment
To adjust the belt tension do the following
(see fig. 13)
:
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 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.
