Steering Control Levers
The machine’s speed and direction are continuously
variable using the two steering controls. The steering
controls can be moved forward or backward about
a neutral position. Furthermore, there is a neutral
position, which is locked if the steering controls are
moved outward.
When both controls are in the neutral position (N), the
machine stands still.
By moving both controls an equal amount forward
or backward, the machine moves in a straight line
forward or backward respectively.
In order, for example, to turn right while moving
forward, move the right control towards the neutral
position. The rotation of the right wheel is reduced and
the machine turns to the right.
8011-789
Steering controls
Zero turn can be achieved by moving one control
backward (behind the neutral position) and carefully
moving the other steering control forward from its
neutral position. The rotation direction when zero
turning is determined by which steering control is
moved backward behind the neutral position. If the left
steering control is pulled backward, the machine turns
to the left. Use extra care when using this maneuver.
Tracking
If the mower is not tracking straight, check the air
pressure in both rear tires. Recommended air pressure
is 15 psi. (1 bar) Tracking must be checked on a at
and level concrete or blacktop surface. If the unit
still does not track straight contact your Husqvarna
workshop for adjustments.
WARNING!
The machine can turn very

Risk for burns if touched.
Allow engine and exhaust
system to cool at least two (2)
minutes before refueling
Experience indicates that alcohol blended
fuels (called gasohol, ethanol or methanol)
can attract moisture which leads to
separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel the
next season. See Storage Instructions for
additional information. Never use engine
or carburetor cleaners in the fuel tank or
permanent damage may occur.

Lifting Lever for the Mower Deck
The deck cutting height is achieved with the foot
pedal. To lift the deck, press the foot pedal forward.
To lower the deck, apply pressure to the top side
of the foot pedal and allow the pedal to pivot while
allowing the lift arm to rotate to the rear of the unit.
To stop at the desired cutting position, rotate the pedal
down into the notch in the height plate. The cutting
height range is from 1½" (38mm) to 5" (127mm) in
½" (13mm) increments. The heights are measured
from the ground up to the blade tip with the engine not
running.
IMPORTANT INFORMATION
In order to obtain an even cutting height it
is important that the air pressure in all four
tires is the same 15 psi (1 bar).
