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 2.50" 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
The deck cutting height is adjustable in 1/4” (6.4 mm)
increments.
To adjust the cutting height, step on the deck lift pedal and
insert the adjusting pin into the desired cutting height hole.
Release the deck lift pedal. Figure 3-9
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 3-10
Anti-scalp wheels can be installed in two positions. With
the wheel installed in the bottom hole, the wheel is located
1.68” (42.7 mm) below the mower blades. This setting is
preferred when mowing at cutting heights of 2-1/2” (63.5
mm) or higher.
When the wheel is mounted in the top hole, it is located .78”
(19.8 mm) below the mower blades. This is the acceptable
setting for mowing at cutting heights of 1-1/2” (38.1mm) or
higher.
