OPERATIONAL CONTROLS
Operation - 25
Throttle Lever (E)
Moving the throttle lever forward
toward the fast position increases the
engine Revolutions Per Minute (RPM). Mov-
ing the throttle lever backward toward the
slow position decreases the engine RPM.
Headlight Switch (F)
Depressing the top (1) of the head-
light switch turns on the headlights
and taillights. Depressing the bottom (2) of
the switch turns the lights off.
Power Take Off (PTO) Switch (G)
Pulling up on the PTO switch engages the electric
clutch to provide power to the front
attachment.
Pushing down on the PTO switch
disengages the electric clutch and
applies the clutch brake to stop the
attachment. NOTE: the PTO will turn
off automatically if the operator leaves
the seat. The PTO can be restarted by
turning the PTO switch off and then on again.

unit, always engage the
parking brake to prevent
accidental movement of
the machine.
To engage the parking
brake, pull the brake
handle back toward the
operator.
To disengage the parking
brake, pull back slightly on
the brake handle to relieve
pressure, push down the
release button (3) on the
top of the handle, and
push the handle forward.
If the parking brake is
set, any attempt to move
the power unit will shut off the engine. If the operator
leaves the seat without first setting the parking brake,
the engine will shut off.
Neutral Assist Lever (I)
Placing the neutral assist lever in
the on position (2) engages the neutral assist
spring to help return the SDLA control levers
to the neutral position. This makes the neu-
tral position easy to select and maintain. The
neutral assist on position is recommended
when learning the operation of the power unit,
loading or unloading, attaching and removing
attachments, and whenever the operator is unsure of
the power unit’s response to the task being performed.
Placing the neutral assist lever in the off position (1)
disengages the neutral assist spring. This position is
designed for experienced operators when using the
power unit in open areas where travel speed and
direction are relatively constant and control is easily
maintained. The neutral assist off position reduces
operator arm fatigue when using the power unit for
prolonged periods of time.
CAUTION
Stopping the power unit with the neutral assist
lever in the off position requires the operator to
manually return the SDLA control lever or foot
pedal to the neutral position.
Front Hitch Lever Lock (J)
The front hitch lever lock prevents the acci-
dental release of the front hitch latch lever. To
release the front hitch latch lever, lift the tab
on the front hitch lever lock and then move the
front hitch latch lever to the unlock position.
Front Hitch Latch Lever (K)
The front hitch latch lever locks
or unlocks the hitch latch.
Raise the front hitch latch lever to unlock
the hitch latch when attaching or detaching
Ventrac attachments.
Lower the front hitch latch lever to lock the
hitch latch over the hitch arm pins on Ventrac
attachments. Ensure the lever is secured in
the frame notch and the front hitch lever lock
is in place.
Auxiliary Hydraulic Quick Couplers (L)
The two couplers are a part of the auxiliary hydrau-
lic circuit and are used with an attachment which
requires hydraulics (e.g. to angle a dozer blade or
rotate the discharge on the snow blower).
