Servicing The Front Roller - Toro Groundsmaster 3500-D Operator's Manual

4. Inspect the cutting edges of all the blades,
sharpen the cutting edges if they are dull or
nicked, sharpen only the top of the cutting edge,
and maintain the original cutting angle to ensure
sharpness (Figure
Note:
The blade remains balanced if the same
amount of metal is removed from both cutting
edges.
Figure 72
1. Sharpen at this angle only.
5. To check the blade for being straight and
parallel, lay the blade on a level surface and
check its ends.
Note:
The ends of the blade must be slightly
lower than the center, and the cutting edge must
be lower than the heel of the blade. This blade
produces a good quality of cut and requires
minimal power from the engine. By contrast,
replace a blade that is higher at the ends than
the center or the cutting edge is higher than the
heel, because the blade is bent or warped.
6. Install the blade with the sail facing toward the
cutting deck, with the anti-scalp cup and blade
bolt.
7. Tighten the blade bolt to 115 to 149 N∙m (85
to110 ft-lb).

Checking the Blade Stopping Time
Service Interval: Before each use or daily
The blades of the cutting deck should completely stop
in 7 seconds after you shut down the cutting deck.
Note:
Ensure that the decks are lowered onto a
clean section of turf or hard surface to avoid thrown
dust and debris.
To verify the stopping time, have a second person
stand back from the deck at least 6 m (20 ft) and
watch the blades on 1 of the cutting decks. Shut
the cutting decks down and record the time that it
takes for the blades to come to a complete stop. If
the time is longer than 7 seconds, the braking valve

needs adjustment; contact your Toro Distributor for
assistance in making this adjustment.
