Steering controls
WARNING!
The machine can turn very
rapidly if one steering control
is moved much further forward
than the other.
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.
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.
