REV F 3-12 604345
IMPORTANT: Both wing decks must be released from
the transport position before lowering them with the side
deck lift switch.
Side deck operation
When the side decks raise beyond 15 degrees, during
operation, the blades on both side decks and center deck will
disengage.
To restart the blades, with the decks in the mowing position,
it will be necessary to cycle the deck clutch switch from the
engaged (up) position to the disengaged (down) position and
then back to the engaged (up) position. Refer to the Deck Clutch
Operation section for more detailed information.
NOTE: The blades on all decks will shut off if one or both of
the side decks raise beyond 15 degrees during operation.
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.
Clutch life will be maximized if these procedures are
followed.
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 1/4” (6.3mm) increments.
The holes in the height adjusting panels are spaced at 1/4”
(6.3mm) intervals.
Use the following procedure to set the deck cutting height:
1. Using the center deck lift switch raise the center deck
until the transport lever is engaged. Figure 3-13
2. Move the pin to the desired cutting height in the center
deck’s height adjusting plate. Figure 3-13
3. Step on the center deck lift switch and pull on the
transport lever to release it. Release the center deck lift
switch. Figure 3-13
4. Using the side deck lift switch, raise the side decks to
their highest position.
5. Shut the engine off.
6. Use the illustration to establish which height adjusting
holes on the side decks to use. Figure 3-14
Height of Cut Range:
A. With the side deck wheels in the top hole (-1 on the
chart) the range of cut is 1.0” to 3.5” (25.4mm to
89mm).
B. With the side deck wheels in the middle hole (0 on
the chart) the range of cut is 2.0” to 4.5” (50.8mm to
114.3mm).
C. With the side deck wheels in the bottom hole (+1 on
Figure 3-12
Make sure that the area around and under the deck is clear
and that there are no bystanders in the immediate area
before proceeding.
