CONTROLS
1. Motion 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 flat and level concrete or blacktop
surface. If unit still does not track straight, contact a
Poulan workshop for adjustment.
