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
disengaged), 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
immediately and contact your Hustler
®
Dealer.
Follow these procedures to maximize clutch life.
1. Engage the clutch only under the following conditions:
• throttle set at approximately 2/3 as shown on
instrument panel;
• deck cutting height set to Notch D or higher;
•no load on the blades.
After clutch engagement, adjust the deck cutting height
to the desired level, if necessary, and advance the engine
throttle to full rpm.
IMPORTANT: Engaging the deck clutch at high engine
rpm, low deck heights 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 1/2" (12.7 mm)
increments.
When the deck cutting height adjusting lever is in the “A”
slot, the deck mowing height is set at its lowest mowing
position. When the lever is located in the “G” slot, the deck
height is at its highest mowing position or transport mode.
To adjust the cutting height, slide the deck cutting height
adjusting lever out of the notch that it is in and raise or lower
it until the desired cutting height is achieved and slide the
lever into that notch. Figure 3-12
Anti-Scalp Wheels
Anti-scalp wheels are standard on these mowers. These
wheels are designed to minimize scalping when mowing on
rough uneven terrain. Figure 3-13
Anti-scalp wheels can be installed in two positions. With
the wheel installed in the bottom hole, the wheel is located
1.60” (40.6mm) below the mower blades. This setting is
preferred when mowing at cutting heights of 2-1/2” (63.5mm)
or higher.
When the wheel is mounted in the top hole, it is located .70”
(17.8mm) below the mower blades. This is the acceptable
setting for mowing at cutting heights of 1-1/2” (38.1mm) or
higher.

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.
