SAFETY INSTRUCTIONS
Personal Safety Equipment
• Make sure that you have first aid equipment 
close at hand when using the machine.
• Never use the machine when barefoot. 
Always wear protective shoes or boots, 
preferably with steel toecaps.
• Always wear approved protective glasses 
or a full visor when assembling or driving.
• Always wear gloves when handling the 
blades.
• Never wear loose clothing that can get caught 
in moving parts.
• Use ear protectors to avoid damage to 
hearing.
Slope Operation
Slopes are a major factor related to loss of 
control and tip-over accidents, which can 
result in severe injury or death. Operation on 
all slopes requires extra caution. If you 
cannot back up the slope or if you feel uneasy 
on it, do not mow it.
• Mow up and down slopes (10 degrees 
maxium), not across.
• Watch for holes, ruts, bumps, rocks, or 
other hidden objects. Uneven terrain 
could overturn the machine. Tall grass 
can hide obstacles.
• Choose a low ground speed so that you 
will not have to stop while on the slope.
• Do not mow on wet grass. Tires may lose 
traction.
• Avoid starting, stopping, or turning on a 
slope. If the tires lose traction, disengage 
the blades and proceed slowly straight 
down the slope.
• Keep all movement on the slopes slow 
and gradual. Do not make sudden 
changes in speed or direction, which 
could cause the machine to roll over.
WARNING!
When using the machine, approved personal protective equipment (shown in 
illustrations) shall be used. Personal protective equipment cannot eliminate 
the risk of injury but it will reduce the degree of injury if an accident does 
happen. Ask your retailer for help in choosing the right equipment.

SAFETY INSTRUCTIONS
• Use extra care while operating machine 
with grass catchers or other attachments; 
they can affect the stability of the 
machine. Do not use on steep slopes.
• Do not try to stabilize the machine by 
putting your foot on the ground.
• Do not mow near drop-offs, ditches, or 
embankments. The machine could 
suddenly roll over if a wheel is over the 
edge or if the edge caves in.
Children
Tragic accidents can occur if the operator is 
not alert to the presence of children. Children 
are often attracted to the machine and the 
mowing activity. Never assume that children 
will remain where you last saw them.
• Keep children out of the mowing area 
and in the watchful care of a responsible 
adult other than the operator.
• Be alert and turn machine off if a child 
enters the area.
• Before and while backing, look behind 
and down for small children.
• Never carry children, even with the 
blades shut off. They may fall off and be 
seriously injured or interfere with safe 
machine operation. Children who have 
been given rides in the past may 
suddenly appear in the mowing area for 
another ride and be run over or backed 
over by the machine.
• Never allow children to operate the 
machine.
• Use extra care when approaching blind 
corners, shrubs, trees, or other objects 
that may block your view of a child.

on a truck or trailer bed with plastic liner. 
Always place containers on the ground 
away from your vehicle when filling.
• Remove gas-powered equipment from 
the truck or trailer and refuel it on the 
ground. If this is not possible, then refuel 
such equipment with a portable 
container, rather than from a gasoline 
dispenser nozzle.
• Keep the nozzle in contact with the rim of 
the fuel tank or container opening at all 
times until fueling is complete. Do not 
use a nozzle lock-open device.

CONTROLS
Controls
This operator’s manual describes the 
Husqvarna Zero Turn Rider. The rider is fitted 
with a Briggs and Stratton four-stroke engine 
developing 22-24 horse power.
Transmission from the engine is made via two 
belt-driven hydrostat transaxles, one for each 
drive wheel. Using the left and right steering 
controls, the flow is regulated and thereby the 
direction and speed.

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 
Husqvarna workshop for adjustment.
