INTRODUCTION
This manual has been prepared for the operators of
the HUSQV ARNA 32", 36" commercial mowers.
Read, understand, and follow the safety and operating
instructions.
Always stop the engine and blades, place the
traction levers in drive, and place the mower in gear
when leaving unattended.
The steering system of this mower uses individual
right and left traction levers on the handle bars.
Squeezing the traction lever will reduce tension on
the wheel drive belt eliminating power to that wheel.
With the opposite wheel still under power a turn is
accomplished. If the traction lever is squeezed even
tighter the brake will be applied to that wheel and a
tighter more abrupt turn is accomplished. LEARN
HOW TO USE THESE IMPORTANT STEERING/
BRAKE CONTROLS!
As an additional safety feature, these mowers are
equipped with an Operators Presence System. This
is an electrical interlock safety system which is
activated by depressing either one or both of the
Operator Presence Levers above the handle grips.
Releasing both Operators Presence Levers while
mowing or transporting will break the electrical circuit
and cause the engine and mower to stop. The mower
will not stop immediately after releasing the O.P.
levers, some travel does occur.

down before engaging the blades or shifting the
transmission into gear. If neither O.P. lever is held the
engine will stop.
INTERLOCK SAFETY SYSTEM
Check the function of the safety electrical system on
a regular basis.
1. Engine must kill if blades are engaged without O.P.
levers held down.
2. Engine must kill if transmission is taken out of
neutral without holding down O.P . levers.
3. Engine must not start unless blades are off and
transmission is in the neutral position.
4. Do not operate the mower if the interlock safety
system allows operating or starting in any unsafe
condition.
CUTTING DECK SERVICE
If mower is cutting improperly , check the following:
1. Ground speed - too fast for proper cutting. Shift to a
lower gear.
2. Engine speed - too low for proper cutting. Increase
engine speed.
3. Cutting height - too low for ground/grass conditions.
Adjust to higher cut.
4. Blade spacers - not positioned properly on all blade
shafts. Visually inspect and replace or adjust as
necessary.
5. Front casters - spacers not in correct relationship
with rear axle. Adjust as necessary.
6. Belt slippage - causing bad cutting pattern or
uneven cut. Adjust belt tension
7. Tire pressure - uneven tire pressure can cause an
uneven cut from one side of the deck to the other.
Equalize tire pressure.

CUTTER HOUSING SPINDLE ASSEMBLIES
The cutter housing assembly is designed with a slip
fit inner race and pulley . The sole purpose of the
setscrew in the pulley is to hold the housing assembly together. The set screw is not meant to secure the
pulley . The pulley is secured by pinching the pulley
to the inner race of the bearings using the blade bolt
and nut. Tighten the setscrews after you have
pinched the assembly together with the blade bolt and
nut.
Models have a different stack up of spacers and
pulleys, to achieve proper belt alignment. See figure
