3. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the
blade meet (Figure

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 (Figure
Note:
The blade remains balanced if the same
amount of metal is removed from both cutting
edges.

1. Sharpen the blade at this angle only.
5. Lay the blade on a level surface and check its
ends to ensure that the blade is straight and
parallel.
Note:
The blade ends must be slightly lower
than the center, and the cutting edge must
be lower than the heel of the blade. These
characteristics produce a good quality of cut and
require less power from the engine.
Note:
If the blade ends are higher than
the center, or if the blade cutting edges are
higher than the heel, replace the blade. These
characteristics indicate that the blade is bent or
warped.
6. Use the anti-scalp cup and blade bolt to install
the blade with the sail facing toward the cutting
deck.

Checking the Blade Stopping Time
Service Interval: Before each use or daily
The cutting-deck blades should stop within 7 seconds
after you shut off the cutting units.
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 an assistant stand
at least 6 m (20 ft) away from the cutting unit and
g031648
watch the blades on 1 of the cutting units. Shut off
the cutting units 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 authorized Toro distributor
for assistance in making this adjustment.
