4. To check blade for being straight and parallel, lay blade
on a level surface and check its ends. Ends of blade
must be slightly lower than the center, and cutting edge
must be lower than the heel of the blade. This blade will
produce good quality of cut and require 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.
5. Install blade, sail facing toward cutting deck, with
anti-scalp cup and blade bolt. Tighten blade bolt to
85–110 ft.-lb. (115–149 N⋅m).
Blade Stopping Time
The blades of the cutting deck are to come to a complete
stop in approximately 5 seconds after the cutting deck
engagement switch is shut down.
Note: Make sure the decks are lowered onto a clean section
of turf or hard surface to avoid thrown dust and debris.
To verify this stopping time, have a second person stand
back from the deck at least 20 feet and watch the blades on
one of the cutting decks. Have the operator shut the cutting
decks down and record the time it takes for the blades to
come to a complete stop. If this time is greater than 7
seconds, the braking valve needs adjustment. Call your
Toro Distributor for assistance in making this adjustment.
Servicing the Front Roller
Inspect front roller for wear, excess wobble or binding.
Service or replace roller or components if any of these
conditions exist.
Disassembly
1. Remove roller mounting bolt (Fig. 16).
2. Insert punch through end of roller housing and drive
opposite bearing out by alternating taps to opposite side
of inner bearing race. There should be a 1/16 in.
(.060 in.) lip of inner race exposed.

3. Push second bearing out in press.
4. Inspect roller housing, bearings, and bearing spacer for
damage (Fig. 16). Replace damaged components and
re-assemble.
Assembly
1. Press first bearing into roller housing (Fig. 16). Press on
outer race only or equally on inner and outer race.
2. Insert spacer (Fig. 16).
3. Press second bearing into roller housing (Fig. 16)
pressing equally on inner and outer race until the inner
race comes in contact with spacer.
4. Install roller assembly into deck frame.
Important
Securing roller assembly with a gap larger
than .060 in. creates a side load on bearing and can lead to
premature bearing failure.
5. Verify that there is no more than a .060 in. gap between
roller assembly and the roller mount brackets of the
deck frame. If there is a gap over .060 in., install
enough 5/8 in. diameter washers to take up the slop.
6. Secure mounting bolt to 80 ft.-lb. (108 N⋅m).
Cutting Deck Storage
If cutting deck is separated from traction unit for any length
of time, install spindle plug (94-2703) in top of spindle to
protect spindle from dust and water.
