Install the new belt and then adjust the tension as follows: See Figure 7.
Front
Engine/Clutch
Adjust the nuts on the spring-loaded idler adjuster bolt until the length of the spring is between 2-
1/2" and 2-9/16". This is the initial belt break in spring length. When the belt is broken in after
several hours of mowing, the running spring length should be between 2-3/4" and 3-1/4". For
maximum belt life, periodic checks every 3-4 hours should be done to make sure the spring length
has not exceeded the recommended running length.
Note: Failure to periodically adjust the belt tension will result in severe belt wear and
premature belt failure.
B. MOWER BLADE REMOVAL, BALANCING & INSTALLATION
Sharp blades can cause bodily injury if not handled properly.
When removing the blade, it is recommended that a block of wood be placed between the blade
and the underside of the mower deck. This will allow the removal of the blade without the need to
hold the blade by hand.
Initial Spring Length (New Belt):
2-1/2" to 2-9/16"
Running Spring Length:
2-3/4" to 3-1/4"
