Servicing The Front Roller - Toro Groundsmaster 4300-D Operator's Manual

Note:
Position the ends of the blade slightly
lower than the center, and the cutting edge lower
than the heel of the blade. This blade produces
a good quality of cut and requires minimal power
from the engine. By contrast a blade that is
higher at the ends than the center, or if cutting
edge is higher than the heel, the blade is bent or
warped and must be replaced.

8. Install the blade, sail facing toward cutting deck,
with the anti-scalp cup and blade bolt. Torque
the blade bolt to 115 to 149 N∙m (85 to 110 ft-lb).
Checking the Blade Stopping Time
Service Interval: Before each use or daily
The blades of the cutting deck should come to a
complete stop in approximately 5 seconds after you
shut down the cutting-deck-engagement switch.
Note:
Make sure that the decks are lowered onto a
clean section of turf or hard surface to avoid thrown
dust and debris.
1. Have a second person stand back from the deck
at least 6 m (20 feet) and watch the blades on
1 of the cutting decks.
2. Shut the cutting decks down and record the time
it takes for the blades to come to a complete
stop.
Note:
If this time is greater than 7 seconds,
the braking valve needs adjustment. Call your
authorized Toro distributor for assistance in
making this adjustment.
