4. Place the neutral lock in the locked (rear) position and
the deck clutch switch disengaged (down) position.
The engine should continue to run without the
operator presence control switches engaged.
5. If the engine fails to stop when the deck clutch switch
is engaged or the neutral lock lever is unlocked and
both operator presence control levers are released,
check the function of the operator presence control
switches. If these switches are not operating properly
(not opening or closing) contact your Authorized
Hustler Dealer.
WARNING: The safety interlock system should
always function per steps 4 and 5. If it does not
function properly, it should be corrected
immediately. Do not operate machine without
properly functioning operator presence control
switches.
Moving unit with stalled engine
If it becomes necessary to move the unit when the engine
is inoperative, the hydraulic pumps are equipped with
bypass valves. Before moving the unit, turn bypass valves
counter clockwise one-half to one revolution. The valve
stems on each hydraulic pump are located near the top and
are identified as a hex stud with a bolt thru it. The valve is
located per Figure 3-6.
Do not tow the machine. Move it by hand or use a winch
to load on a trailer for transporting.
When transporting on another vehicle, the unit must be
tied down to the transporting vehicle.
IMPORTANT: Always make certain the two bypass
valves are returned to their operating position before running
the unit following repairs.
Steering the unit
DANGER: Never make sudden stops or reverse
direction, especially when operating on a slope.
The steering is designed for sensitive response.
Rapid rotation of the H-bar handle in either
direction could result in a reaction of the tractor
that can cause serious injury.
After starting engine, release the neutral lock lever (move
it forward) and steer as follows:
To go forward, rotate H-bar handle forward (Fig. 3-7).
To go in reverse, rotate the H-bar handle to the neutral
position. After achieving neutral, rotate lever rearward.
To turn left, rotate the H-bar handle to the left and out of
the neutral position.
To turn right, rotate the H-bar handle to the right and out
of the neutral position.
To zero turn, rotate H-bar handle the direction desired
with the handle in the neutral position. This will allow the
drive wheels to counter-rotate.
To stop or decrease speed, move H-bar handle to neutral.
When going forward rotate handle rearward gently. When
going in reverse rotate handle forward.
DANGER: When traveling in reverse rotate
handle forward gently and avoid sudden
movement. Any sudden movement could cause
the front of the mower to come off of the ground
resulting in possible loss of control.
To increase speed, rotate the H-bar handle’s distance
further from neutral. The farther the H-bar handle is rotated
forward from neutral, the faster unit will travel forward.
The farther the H-bar handle is rotated rearward from
neutral, the faster unit will go in reverse.
Mower deck leveling
The mower deck has three areas that may need to be
checked and adjusted periodically. Before considering any
mower deck leveling adjustments, check that the tire air
pressure is within the specified range.
Deck level adjustments
Leveling the deck must be done in the following manner
and order:
1. Check tire pressures to make certain they are properly
inflated before starting to level deck. The
