require a brief break-in period. Refer to the
Maintenance and Adjustments
section of this manual for more
details.
Deck Clutch Operation
Before beginning operation, check to make sure the deck
clutch switch is engaging and disengaging the blades properly.
To check the deck clutch switch:
1.
Start the engine and engage the deck clutch.
2.
With the deck clutch switch up (clutch engaged) and
the engine running, listen to confirm that the mower
blades are rotating.
3.
Now, push the deck clutch switch down (clutch disen-
gaged), and with the engine running, listen to confirm
that the blades have stopped rotating.
4.
If the mower blades continue to rotate with the deck
clutch switch down, discontinue operation immedi-
ately and contact your Hustler
®
Dealer.
Follow these procedures to maximize clutch life:
1. Engage the clutch
only when the throttle is set at
approximately
2/3 throttle
and there is
no load
on the
blades. After clutch engagement, advance the engine
throttle to full rpm.
Engaging the deck clutch at high engine rpm or when
under heavy load (in tall grass, for example) can cause
belts and/or electric clutch to slip, resulting in premature
wear or possible damage.
2. Disengage the clutch
only when the throttle is set at
less than 1/2 throttle.
Never disengage the clutch with the engine running at
high rpm. Setting the throttle to less than 1/2 throttle
when disengaging the clutch will help extend clutch life.
Warranty will not be allowed
for deck clutches that fail due
to improper engagement and disengagement practices.
Deck Cutting Height Adjustment
Deck cutting height is adjustable in 6.4mm increments.
The holes in the height adjusting bar are spaced at 12.7mm
intervals. By turning the height adjusting stop around, 6.4mm
increments can be attained due to the 6.4mm plate that is
part of the stop. Figure 3-15
EXAMPLE:
When the height adjusting stop is placed in the
76.2mm hole,
with the 6.4mm plate facing to the front of the
unit,
the cutting height is at 76.2mm. When the height adjust-
ing stop is placed in the 76.2mm hole,
with the 6.4mm plate
on the operator’s side of the hole,
the cutting height is at
82.6mm.
The notch located at the rear
of the height adjusting bar
engages the stop handle when the deck lift pedal is fully
depressed. This sets the deck in
transport mode
.
Air Flow Baffles
The decks are equipped with front adjustable air flow
baffles. These baffles can be adjusted up or down, depending
upon the mowing conditions, to provide the best quality of
cut. Figure 3-16
NOTE:
The air flow baffles are preset at the factory in the
“B” setting.
The air flow baffles for the 54" decks come with two sets of
holes per baffle. The baffle mounting hardware must be
removed and the baffle moved up or down and the hardware
re-installed in the correct set of holes and tightened.
Figure 3-16
Never attempt to make any adjustments to the
mower deck while the engine is running or with the
deck drive clutch engaged. Mower blades cannot
be seen and are located very close to the deck
housing. Fingers and toes can be cut off instantly.
Make sure that the area around and under the deck
is clear and that there are no bystanders in the
immediate area before proceeding.
