Adjusting Mower Belt Tension; Adjusting The Blade Brake - Toro 30164 Operator's Manual

Adjusting Mower Belt Tension

Service Interval/Specification
Check belt tension after the first hour of operation
and at least twice during the first 24 hours of
operation.
IMPORTANT: Belt must be tight enough to not
slip during heavy loads while cutting grass. Over
tensioning will reduce belt and spindle bearing
life.
1. Set the parking brake, and turn the ignition key
to "OFF" to stop the engine. Remove the key
and spark plug wire.
2. Loosen locknut on turnbuckle (Fig. 50).
3. Rotate turnbuckle toward rear of mower to
increase tension on belt. Rotate turnbuckle
toward front of mower to decrease tension on
belt (Fig. 50).
Note: The eyebolt threads on both ends of the
turnbuckle should be engaged a
minimum of 5/16" (8mm).

Adjusting the Blade Brake

1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
"OFF" to stop the engine. Remove the key and
spark plug wire.
2. If necessary, adjust the spring mounting bolts so
that the blade brake pad rubs against the pulley
edges (Fig. 51).
3. Adjust the nut at the end of the blade brake rod
until there is 1/8" (3mm)–3/16" (5mm) between
the nut and spacer (Fig. 51).
4. Engage the blades. Ensure the blade brake pad
no longer contacts the pulley edges.
