Toro Groundsmaster 3505-D Operator's Manual page 58

Note:
Position the ends of the blade slightly
lower than the center, and the cutting edge lower
than the heel of the blade. This blade produces
a good quality of cut and requires 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.
1. Cutting edge
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
unit.
7. Tighten the blade bolt to 115 to 149 N∙m (85 to
110 ft-lb).
Checking the Blade Stopping Time
Service Interval: Before each use or daily
The cutting unit blades should stop within 7 seconds
after you shut off the cutting units.
Note:
Ensure that the cutting units are lowered onto
a clean section of turf or hard surface to avoid thrown
dust and debris.
Figure 75
2. Heel
To verify the stopping time, have an assistant stand
at least 6 m (20 ft) away from the cutting unit and
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.
