Checking The Blade-Stopping Time; Selecting A Blade; Choosing Accessories - Toro Groundsmaster 4500-D Operator's Manual

Checking the
Blade-Stopping Time
Service Interval: Before each use or daily
Note:
Lower the decks onto a clean section of turf or
hard surface to avoid throwing dust and debris.
To verify this stopping time, have someone stand
back from the decks at least 6 m (20 ft) and watch
the blades on 1 of the mower decks. Disengage the
mower decks and record the time it takes for the
blades to come to a complete stop. If this time is
greater than 7 seconds, adjust the braking valve. Call
your Toro Distributor for assistance in making this
adjustment.

Selecting a Blade

Standard Combination Sail
This blade provides excellent lift and dispersion in
almost any condition. If you require more or less lift
and discharge velocity, consider a different blade.
Attributes: Excellent lift and dispersion in most
conditions.
Angled Sail
This blade generally performs best in lower heights of
cut—1.9 to 6.4 cm (3/4 to 2-1/2 inches).
Attributes:
•
Discharge remains more even at lower heights of
cut.

Choosing Accessories

Grass Cutting—1.9 to
4.4 cm (0.75 to 1.75
inch) height of cut
Grass Cutting—5 to 6.4
cm (2.00 to 2.50 inch)
height of cut
Grass Cutting—7 to 10
cm (2.75 to 4.00 inch)
height of cut
Leaf Mulching

•
Discharge has less tendency to throw left and
thus leaves a cleaner look around bunkers and
fairways.
•
Lower power is required at lower heights and
dense turf.
High-Lift, Parallel Sail
The blade generally performs better in the higher
heights of cut—7 to 10 cm (2 to 4 inches).
Attributes:
•
It has more lift and a higher discharge velocity.
•
Sparse or limp turf is picked up significantly at
higher heights of cut.
•
Wet or sticky clippings are discharged more
efficiently, reducing congestion in the deck.
•
It requires more horsepower to run.
•
It tends to discharge further left and can tend to
windrow at lower heights of cut.
DANGER
Using the high-lift blade with the mulching
baffle could cause the blade to break,
resulting in personal injury or death.
Do not use the high-lift blade with the baffle.
Atomic Blade
This blade was designed to provide excellent leaf
mulching.
Attributes: Excellent leaf mulching
Mulching Baffle
Has been shown to
improve dispersion and
after cut performance
on northern grasses that
are cut at least 3 times
per week and less than
1/3 of the grass blade
is removed; do not
use with the high-lift,
parallel-sail blade
Use with combination
sail or angle sail blade

Roller Scraper
Can be used any time
that rollers build up
with grass or large flat
grass clumps of grass
are seen; the scrapers
may actually increase
clumping in certain
applications.
