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

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, turn the ignition key to off, and
remove the key.
2. Wait for all moving parts to stop before leaving the
operating position and then chock or block tires.
3. Loosen the locknut on the turnbuckle (Fig. 58).
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. 58).
Note: The eyebolt threads on both ends of the
turnbuckle should be engaged a minimum of 5/16 in.
(8 mm).
Adjusting the Blade Brake
1. Disengage the PTO, turn the ignition key to off, and
remove the key.
2. Wait for all moving parts to stop before leaving the
operating position and then chock or block tires.
3. If necessary, adjust the spring mounting bolts so that the
blade brake pad rubs against the pulley edges (Fig. 60).

4. Adjust the nut at the end of the blade brake rod until
there is 1/8–3/16 in. (3–5 mm) between the nut and the
spacer (Fig. 60).
5. Engage the blades, and ensure that the blade brake pad
no longer contacts the pulley edges.
Replacing the Grass Deflector
An uncovered discharge opening could allow the
lawn mower to throw objects in the operator’s or
bystander’s direction and result in serious injury.
Also, contact with the blade could occur.
Never operate the lawn mower unless you install a
cover plate, a mulch plate, or a grass chute and
catcher.
Warning
1. Disengage the PTO, turn the ignition key to off, and
remove the key.
2. Wait for all moving parts to stop before leaving the
operating position and then chock or block tires.
