Adjusting The Mower Belt Tension; Adjusting The Blade Brake; Replacing The Grass Deflector - Toro 30527 Operator's Manual

Adjusting the Mower Belt
Tension
Service Interval/Specification
Check the belt tension after the first 8 operating hours and
25 operating hours thereafter. Check the belt tension after
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 blade control (PTO).
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position and then set the
parking brake.
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).

4. Adjust the nut at the end of the blade brake rod until
there is 1/8–3/16 inch (3–5 mm) between the nut and
the spacer (Fig. 61).
5. Engage the blades, and ensure that the blade brake pad
no longer contacts the pulley edges.
6. Ensure that there is downward spring force on deflector
(Fig. 62).
7. Tighten the bolt and locknut until they lightly contact
the pivot brackets (Fig. 62).
Important
The grass deflector must be spring-loaded in
the down position. Lift the deflector up to check that it
snaps to the fully down position.

Replacing the Grass Deflector

Warning
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.
