Ground Drive Belt Adjustment
The ground drive belt spring tension is preset at the
factory and does not need readjusting until the belt
stretches and wears. As the belt wears, the spring
tension may need adjusting.
Refer to Figure 3-9 & Figure 3-10:
Check spring length to verify if belt is tensioned correctly.
Installed spring length should be 4" +/- 1/4". Vary the
spring length by adjusting the length of eye bolt.

Excessive belt tension may lead to premature damage to
belt and drive components and is also a safety hazard to
the operator and bystanders. Not enough belt tension
may also lead to premature belt damage due to
excessive belt slippage.

Deck Drive Belt Adjustment
The spindle belt remains in constant tension by means of
a spring tensioned idler. The spring tension should be
adjusted so that the belt does not slip under normal
operating load conditions and may require readjusting as
the belt stretches and wears. The belt should be
replaced if it is excessively worn or damaged.
Refer to Figure 3-11 & Figure 3-12:
Check spring length to verify if belt is tensioned correctly.
Installed spring length should be 4 3/4" +/- 1/8". Vary the
spring length by adjusting the length of the eye bolt.
