Blade Safety; Servicing The Blade - Toro Groundsmaster 3500-D Operator's Manual

2. Insert a punch through the end of the roller
housing and drive the opposite bearing out
by alternating taps to the opposite side of
inner-bearing race.
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.
4. Inspect the roller housing, bearings, and bearing
spacer for damage
Note:
Replace damaged components and
assemble the front roller.
Installing the Front Roller
1. Pressing on the outer race only or equally on the
inner and outer race, press the first bearing into
the roller housing
Note:
Press on the outer race only or equally
on the inner and outer race.
2. Insert the spacer
3. Pressing on outer race only or equally on the
inner and outer race, press the second bearing
into the roller housing until it contacts the spacer
(Figure 71).
4. Install the roller assembly into the deck frame.
Important:
Securing the roller assembly
with a gap larger than 1.5 mm (0.06 inch)
creates a side load on the bearing and can
lead to premature bearing failure.
5. Verify that there is no more than a 1.5 mm (0.06
inch) gap between the roller assembly and the
roller-mount brackets of the deck frame.
Note:
If there is a gap over 1.5 mm (0.06 inch),
install enough 5/8-inch diameter washers to take
up the slop.
6. Torque the mounting bolt to 108 N∙m (80 ft-lb).

Blade Safety

A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death.
•
Inspect the blade periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.

Servicing the Blade

Removing the Blade
Replace the blade if it hits a solid object, if it is out
of balance, or if it is bent. Always use genuine Toro
replacement blades to ensure safety and optimum
performance. Never use replacement blades made
by other manufacturers, because they could be
dangerous.
1. Perform the pre-maintenance procedure; refer
to Maintenance Safety (page
2. Block the cutting deck to prevent it from falling
accidentally.
3. Grasp the end of the blade using a rag or
thickly padded glove and remove the blade bolt,
anti-scalp cup, and blade from the spindle shaft
(Figure 72).
1. Blade bolt
4. Use the anti-scalp cup and blade bolt to install
the blade with the sail facing toward the cutting
deck (Figure 72).
5. Torque the blade bolt to 115 to 149 N∙m (85 to
110 ft-lb).
Inspecting and Sharpening the
Blade
Note:
Check the blade before using the machine.
Sand and abrasive material can wear away the metal
that connects the flat and curved parts of the blade. If
you notice wear, replace the blade; refer to
the Blade (page 56).
