Driving on Slopes
Driving on slopes is one of the operations
where the risk is greatest that the driver will
lose controlor the machine will tipover,which
can result in serious injury or death. All
slopes require extra caution. If you cannot
reverse up a slope or if you feel unsure,
do not mow the slope.
Do as follows
• Remove obstacles such as stones,
tree branches, etc.
• Watch out for and avoid driving over
furrows, holes, and bumps. On uneven
terrain, the machine can tip more easily.
Long grass can hide obstacles.
• Mow up and down, not side-to-side.
• If machine stops while going uphill,
disengage blades and back down slowly.
• Drive evenly and slowly. Use small
movements of the motion control levers.
• Be extra cautious with any additional
equipment, which can alter the
machine’s stability.
Do not
• Do not make sudden changes in speed
or direction.
• Do not drive the machine on terrain that
slopes more than 10°.
• Do not mow near verges, ditches, or
banks. The machine can suddenly spin
around if a wheel goes over the edge of
adroporditch,orifanedgegivesway.
• Do not mow wet grass. It is slippery, and
the tires can lose their grip, so that the
machine slides.
• Avoid unnecessary turns on slopes, and
if it proves necessary, turn slowly and
gradually downward, if possible.
8011-634
Mow up and down, not side-to-side
8011-63
Be extra cautious when driving on slopes
• Avoid starting or stopping on a slope. If
the tires begin to slip, shut off the blades
and drive slowly straight down the slope.

SAFETY INSTRUCTIONS
Children
• Serious accidentsmay occurif you fail to
be on guard for children in the vicinity of
the machine.Children are often attracted
to the machine and mowing work. Never
assume that children will stay where you
last saw them.
• Keepchildrenawayfromthemowing
area and under close supervision by
another adult.
• Keep an eye out and shut off the
machine if children enter the work area.
• Beforeand duringa reversing maneuver,
look backward and downward for small
children.
• Never allow a child to ride with you.
They can fall off and injure themselves
seriously or prevent risk-free
maneuvering of the machine.
• Never allow children to operate the
machine.
• Be particularly cautious near corners,
bushes, trees, or other objects that block
your view.

SAFETY INSTRUCTIONS
Maintenance
WARNING!
The engine must not be started when the protective plate for the mower deck’s
drive belt is removed.
• Stop the engine. Prevent the enginefrom
starting by removing the spark plug
cables from the spark plugs or by
removing the ignition key before making
any adjustments or performing
maintenance.

vicinity of sparks or open flames.
• If leaks arise in the fuel system, the
engine must not be started until the
problem has been resolved.
• Store the machine and fuel in sucha way
that there is no risk of leaking fuel or fuel
vapor leading t o damages.
• Check the fuel level before each use and
leave space for the fuel to expand,
because the heat from the engine and
the sun may otherwise cause the fuel to
expand and overflow.
• Avoid overfilling. If you spill fuel on the
machine,wipe up the spill and wait untilit
has evaporated before starting the
engine. If you have spilled fuel on your
clothing, change your clothing.

This operator’s manual describes the
Husqvarna Walk-Behind Mowers
WH4817EFQ and WH5219EFQ. The
machines are fitted with a Kawasaki fourstroke V-Twin engine, for data See “Technical
Data” on page 61.
Transmission from the engine is made via two
belt-driven hydraulic pumps, which in turn
drive a hydraulic motor for each drive wheel.
Using the left and right steering controls, the
flow is regulated and thereby the direction
and speed.

1. Ground Speed Lever
Located in the center of the console. Controls
the forward speed of the mower. Push the
lever forward if you want to go faster, pull it
back to go slower or pull it all the way back to
the stop postion.
To begin motion, the operator must move the
ground speed lever forward before
disengaging the neutral lock bail.
Ground Speed Lever Stop is the adjustment
screw placed on the front edge of the console
panel. It is used to insure ground speed lever
does not over travel motion control levers into
revese.
2. Choke Control
8011-415
Ground Speed Lever
The choke control is used for cold starts to
provide the engine with a richer fuel mixture.
For cold starts the choke control should be
pulled out.
Push the choke control gradually in when the
engine is started till the engine runs smoothly.
Do not use the choke control when starting a
warm engine.
3. Ignition Switch
The ignition key switch is placed on the
console panel and is also used to start the
machine when it is equipped with an electric
starter.

4. Operator Presence Lever
Located on the handle. 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 at 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 Operator
Presence levers, some travel does occur.
One or both levers must be pressed against
the handle for the engine to remain running,
when the blades are engaged or neutral lock
bail is not locked in motion control levers.
8011-661

5. Throttle Control
The throttle control regulates the engine
speed and thereby the rate of rotation of the
blades, assuming the control for engaging the
mower deck is pulled out, see Engaging the
Mower Deck.
In order to increase or decrease the engine
speed, the control is moved forward or
backward respectively.
Avoid idling the engine for long periods, as
there is a risk of the spark plugs fouling.
USE FULL THROTTLE WHEN MOWING, for
best mower performance and best battery
charging rate.

6. Blade Engagement Switch
In order to engage the blades, pull the knob
out. The blades are disengaged when the
knob is depressed.
The switch energizes the clutch for the V-belt
pulley, placed on the crankshaft, to drive the
blades.
7. Neutral Bail
Keeps the unit from moving while idling. The
neutral bail will lock the motion control levers
in neutral position and must be activated
when starting the engine.
8011-655
Engaging the mower deck
To engage the neutral bail, pull the Ground
Speed Lever fully back and press up the bail
into position according to illustration.
Parking Brake
The machine is braked by the hydraulic

8. Hour Meter
The hour meter displays the total operating
time.
It will flash CHG OIL (Change Oil) at 50 hour
intervals. The flash duration is one hour
before and one hour after the interval. The
CHG OIL icon will come on and shut off
automatically. The hour meter can not be
manually reset.
9. Motion control levers
8011-691
Hour meter
The machine’s speed and direction are
continuously variable using the two motion
control levers.
When both controls are in the neutral
position, the machine stands still. The
controls can be locked in neutral position by
the Neutral bail.
By moving both controls an equal amount
forward the machine moves in a straight line
forward.
WARNING !
The machine can turn very
rapidly if one motion control
levers is moved much further
than the other.
In order, for example, to turn right while
moving forward, move the right control
towards the handle (neutral position). The
rotation of the right wheel is reduced and the
machine turns to the right.

10. Tracking Knob
Located on the right side of the ground speed
lever. If the mower will not travel in a straight
line on a smooth surface, turn the tracking
knob the proper direction until it straightens
out.
The tracking bolt is a set-screw used for
adjustment, if the tracking knob adjustment
range is inadequate.
11. Refueling
The machine has one fuel tank. The tank
volume is 5.3 gallon / 20 liters.
The engine should be run on a minimum of
87-octane unleaded gasoline (no oil mix).
See “Technical Data” on page 61 concerning
methanol and ethanol fuels.

IMPORTANT INFORMATION
Experience indicates that alcohol
blended fuels (called gasohol or using

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 the 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
