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

Note: Because sand and abrasive material can wear
away the metal that connects the flat and curved parts
of the blade, check the blade before using the machine.
If you notice wear, replace the blade; refer to
the Blade (page 51).

1. Cutting edge
2. Sail
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
Note: The blade remains balanced if the same amount
of metal is removed from both cutting edges.
Figure 69
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.

Servicing the Front Roller

Inspect the front roller for wear, excess wobble, or binding.

Note: There should be a 1.5 mm (0.06 inch) lip of
inner race exposed.
3. Push the second bearing out in the press.
