Safety Rules & Information
GENERAL OPERATION
• Read, understand, and follow all instructions in the manual
and on the unit before starting.
• Only allow responsible adults, who are familiar with the
instructions, to operate the unit.
• Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown by the blade(s).
• Be sure the area is clear of other people before mowing.
Stop unit if anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless absolutely necessary. Always
look down and behind before and while travelling in reverse.
• Be aware of the mower discharge direction and do not
point it at anyone. Do not operate the mower without either
the entire grass catcher or the deflector in place.
• Slow down before turning.
• Never leave a running unit unattended. Always disengage
the PTO, set parking brake, stop engine, and remove keys
before dismounting.
• Disengage the PTO lever to stop the blades when not
mowing.
• Stop engine before removing grass catcher or unclogging
chute.
• Mow only in daylight or good artificial light.
• Do not operate the unit while under the influence of alcohol
or drugs.
• Watch for traffic when operating near or crossing roadways.
• Use extra care when loading or unloading the unit into a
trailer or truck.
• Data indicates that operators, age 60 years and above, are
involved in a large percentage of riding mower-related
injuries.These operators should evaluate their ability to
operate the riding mower safely enough to protect them-
selves and others from injury.
• Keep in mind the operator is responsible for accidents
occurring to other people or property.
• All drivers should seek and obtain professional and practi-
cal instruction.
• Always wear substantial footwear and trousers. Never
operate when barefoot or wearing sandals.
• Before using, always visually check that the blades and
blade hardware are present, in-tact, and secure. Replace
worn or damaged parts.
• Never operate the machine with defective guards, or with-
out safety protective devises in place.
• Disengage attachments before: refuelling, removing an
attachment, making adjustments (unless the adjustment
can be made from the operator’s position).
• When the machine is parked, stored, or left unattended,
lower the cutting means .
Slopes are a major factor related to loss-of-control and tip-
over accidents, which can result in severe injury or death.
All slopes require extra caution. If you cannot back up
the slope or if you feel uneasy on it, do not drive on it.
Control of a ride-on machine sliding on a slope will not be
regained by the application of the brake. The main reasons
for loss of control are: insufficient tire grip on the ground,
speed too fast, inadequate braking, the type of machine is
unsuitable for it’s task, lack of awareness of the ground con-
ditions, incorrect hitching and load distribution.
Do
• See your authorized dealer for recommendations of available
weights to improve stability.
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain could overturn
the unit.Tall grass can hide obstacles.
• Use slow speed. Choose a low gear so that you will not have to
stop or shift while on the slope.
• Use extra care with grass catchers or other attachments.These
can change the stability of the unit.
• Keep all movement on the slopes slow and gradual. Do not
make sudden changes in speed or direction.
Do Not
• Do not start or stop on a slope. If tires lose traction, disengage
the blade(s) and proceed slowly straight down the slope.
• Do not turn on slopes unless necessary, and then, turn slowly
and gradually uphill, if possible.
• Do not mow near drop-offs, ditches, or embankments.The
mower could suddenly turn over if a wheel is over the edge of a
cliff or ditch, or if an edge caves in.
• Do not mow on wet grass.Reduced traction could cause slid-
ing.
• Do not try to stabilize the unit by putting your foot on the
ground.
• Do not use grass catcher on steep slopes.
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of
unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.This mowing
deck is capable of amputating hands and feet and throwing objects.The triangle in text signifies impor-
tant cautions or warnings which must be followed.
Never operate on slopes greater than 17,6 percent (10°)
which is a rise of 1m vertically in 6m horizontally.
When operating on slopes use additional wheel weights or
counterweights.See your dealer to determine which weights
which weights are available and appropriate for your unit.
Select slow ground speed before driving onto slope.In
addition to front and rear weights, use extra caution when
operating on slopes with rear-mounted grass catcher.
Mow UP and DOWN the slope, never across the face, use
caution when changing directions and DO NOT START OR
STOP ON SLOPE.

Safety Rules & Information
CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will
remain where you last saw them.
• Keep children out of the mowing area and under the
watchful care of another responsible adult.
• Be alert and turn unit off if children enter the area.
• Before and during reverse operation, look behind and
down for small children.
• Never carry children. They may fall off and be seriously
injured or interfere with safe unit operation.
• Never allow children to operate the unit.
• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
TRANSPORTING AND STORAGE
•Always observe safe refueling and fuel handling prac-
tices when refueling the unit after transportation or stor-
age.
• Always follow the engine manual instructions for stor-
age preparations before storing the unit for both short
and long term periods.
• Always follow the engine manual instructions for proper
start-up procedures when returning the unit to service.
• Never store the unit or fuel container inside where there
is an open flame or pilot light, such as in a water heater.
Allow unit to cool before storing.
• Stop and inspect the equipment if you strike an object.
Repair, if necessary, before restarting.
• Never make adjustments or repairs with the engine run-
ning unless specified otherwise in the engine manufac-
turer’s manual.
• Grass catcher components are subject to wear, dam-
age, and deterioration, which could expose moving parts
or allow objects to be thrown. Frequently check compo-
nents and replace with manufacturer’s recommended
parts, when necessary.
• Mower blades are sharp and can cut. Wrap the blade(s)
or wear gloves, and use extra caution when servicing
them.
• Check brake operation frequently. Adjust and service as
required.
• Use only factory authorized replacement parts when
making repairs.
• Always comply with factory specifications on all settings
and adjustments.
• Only authorized service locations should be utilized for
major service and repair requirements.
• Never attempt to make major repairs on this unit unless
you have been properly trained. Improper service proce-
dures can result in hazardous operation, equipment
damage and voiding of manufacturer’s warranty.
• If fuel is spilled, do not attempt to start the engine but
move the machine away from the area of spillage and
avoid creating any source of ignition until petrol vapors
have dissipated.
• Replace all fuel tank caps and fuel container caps
securely.
• On multiple blade mowers, take care as rotating one
blade can cause other blades to rotate.
• Do not change engine governor settings or over-speed
the engine. Operating the engine at excessive speed
can increase the hazard of personal injury.
• Disengage drive attachments, stop the engine, remove
the key, and disconnect the spark plug wire(s) before:
clearing attachment blockages and chutes, performing
service work, striking an object, or if the unit vibrates
abnormally. After striking an object, inspect the machine
for damage and make repairs before restarting and
operating the equipment.
• Never place hands near the hydro pump cooling fan
when the unit is running. Cooling fan is located on top of
transaxle.
When transporting this tractor on an open trailer, make
sure unit is facing forward, toward the direction of travel. If
tractor is facing backward, wind lift could cause damage to
the hood.

Features & Controls
CONTROL FUNCTIONS
The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing
require the combined use of several controls applied in specific sequences.To learn what combination and sequence of
controls to use for various tasks see the OPERATION section.
Figure 1. Tractor & Mower Controls
Please take a moment and familiarize
yourself with the name, location, and
function of these controls so that you
will better understand the safety and
operating instructions provided in this
manual.
Trans. Release
Lever on Rear
of Tractor
Throttle / Choke Control
The throttle controls engine speed. Move the throttle up
to increase engine speed and down to decrease engine
speed. Always operate at FULL throttle.
Note: Moving the throttle control fully forward closes the
choke. A warm engine may not require choking.
PTO Lever
The PTO (Power Take-Off) lever engages and disengages
the blades.To engage the PTO, move the lever forward. To
disengage the PTO, move the lever all the way back.You
will feel the lever lock into both the engaged and disen-
gaged positions.
Note: The operator must be seated firmly in the tractor
seat for the PTO to function. Also note that the tractor
will not start unless the lever is in the disengaged
position.
Ground Speed Control Pedal
The tractor’s forward & reverse ground speed is con-
trolled by the ground speed pedals.
The ground speed is selected from a continuous range.
Depressing the FORWARD pedal increases FORWARD
tractor motion, depressing the REVERSE pedal increas-
es REVERSE tractor motion.The further either pedal is
depressed, the faster the tractor will travel.
Note: Depressing the clutch/brake pedal is NOT neces-
sary when changing speeds or directions. Releasing the
groend speed pedal puts the transmission in NEUTRAL,
and stops tractor motion. (Apply & set the Parking Brake
before leaving the operator’s position).
Always mow with the engine speed at full throttle.
Note: If the terrain is rough, hilly, or sloping, use a slower
forward speed. If the grass is wet or over 76 mm high,
use full engine speed with a low forward speed so the
mower will have enough power to cut the grass.
