All drive belts are spring loaded and self-tensioning,
however after the first 2, 4, 8 and 10 hours of operation,
the belts should be checked for proper alignment and wear.
Thereafter, check the belts after every 40 hours of operation
or weekly, whichever occurs first.

If the pump drive belt fails, steering control will be
lost which could result in serious injury or death.

CUTTER DECk ADJUSTMENTS
6.8
Cutter deck level, pitch and height are set at the factory.
However, if these adjustments should ever need to be
made, the following procedures will aid in obtaining the
proper cutter deck adjustment.
- NOTE -
Before proceeding with the cutter deck adjustments,
be sure that all tires are properly inflated.
CUTTER DECk LEvEL
The cutter deck should be level from side-to-side for
proper cutting performance. To check for level, be sure
that the mower is on a flat, level surface, the tires are
properly inflated and the cutter deck is set at the most
common cutting height that you will use. On the RH side
of the machine, check the distance from the top of the
cutter deck to the floor. Next check the distance from the
top of the cutter deck to the floor on the LH side of the
machine. Both measurements should be the same. If the
two measurements are different, the cutter deck level must
be adjusted as follows:
If the cutter deck is lower on one side, loosen the
1.
elastic stop nuts securing the hanger chains to the
cutter deck on the front and rear of the lower side.
See Figure 6-5.
