Note: If the assist arm does not contact the front stop on
the mower deck (Fig. 59), adjust the clevis to bring the

adjustment (Fig. 59).
Note: The distance between the belt guide and the
mower belt should be 1-3/8 inch (35 mm) when you
engage the mower belt (Fig. 60). Adjust the mower belt
as necessary. The disengaged belt should not drag or
fall off the pulley when the guides are properly
adjusted.

Adjusting the Mower Belt
Tension
Service Interval/Specification
Check the belt tension after the first 8 and 25 hours of
operation. Check the belt tension every 50 operating hours.
Important
The belt must be tight enough to not slip
during heavy loads while cutting grass. Over tensioning the
belt will reduce the bearing life of the belt and the spindle.
1. Disengage the PTO and set the parking brake.
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. Loosen the locknut on the turnbuckle (Fig. 59).
4. Rotate the turnbuckle toward the rear of the mower to
increase the tension on the belt. Rotate the turnbuckle
toward the front of the mower to decrease the tension
on the belt (Fig. 59).
Note: The eyebolt threads on both ends of the
turnbuckle should be engaged a minimum of 5/16 inch
(8 mm).
Adjusting the Blade Brake
1. Disengage the PTO and set the parking brake.
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. If necessary, adjust the spring mounting bolts so that the
blade brake pad rubs against the pulley edges (Fig. 61).

the spacer (Fig. 61).
