Before Operation
Before Operation Safety
• Do not allow children or untrained people to operate or service the machine. Local
regulations may restrict the age of the operator. The owner is responsible for training all
operators and mechanics.
• Inspect the area where you will use the machine and remove all objects that could be
thrown or could interfere with the operation of the machine.
• Evaluate the terrain to determine the appropriate equipment and any attachments or
accessories required to operate the machine properly and safely.
• Do not carry passengers on the machine.
• Become familiar with the safe operation of the equipment, operator controls, and safety
signs.
• Check that operator-presence controls, safety switches, and guards are attached and
working properly. Do not operate the machine unless they are functioning properly.
• Wear appropriate clothing, including eye protection; long pants; substantial, slip-resistant
footwear; and hearing protection. Tie back long hair and do not wear loose clothing or
loose jewelry.
• Do not operate the machine unless all guards and safety devices, such as the deflectors
and the entire grass catcher, are in place and functioning properly. Replace worn or
deteriorated parts when necessary.
• Shut off the engine, remove the key, and wait for all moving parts to stop before leaving
the operator’s position. Wait for the machine to cool before servicing, adjusting, fueling,
cleaning, or storing it.
WARNING
Contacting the blade can result in serious personal injury.
When you shut off the engine, the blade(s) should stop. If not, stop using your
machine immediately and contact an Authorized Service Dealer.
• Before mowing, inspect the machine to ensure that the cutting assemblies are working
properly.
Operation Page 4–1 3473-292 B
Before Operation Safety (continued)
• Keep bystanders, particularly children, and pets away from the machine during
operation. Shut off the machine and attachment(s) if anyone enters the area.
Fuel Safety
• Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn
you and others and can damage property.
– To prevent a static charge from igniting the fuel, place the container and/or machine
directly on the ground before filling, not in a vehicle or on an object.
– Fill the fuel tank outdoors on level ground, in an open area, and when the engine is
cold. Wipe up any fuel that spills.
– Do not handle fuel when smoking or around an open flame or sparks.
– Do not remove the fuel cap or add fuel to the tank while the engine is running or hot.
– If you spill fuel, do not attempt to start the engine. Avoid creating a source of ignition
until the fuel vapors have dissipated.
– Store fuel in an approved container and keep it out of the reach of children.
• Do not overfill the fuel tank. Replace the fuel cap and tighten it securely.
• In certain conditions during fueling, static electricity can be released, causing a spark that
can ignite fuel vapors.
• Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner.
Always place containers on the ground and away from your vehicle before filling.
• Remove the equipment from the truck or trailer and refuel it while it is on the ground. If
this is not possible, then refuel from a portable container rather than from a fuel-
dispenser nozzle.
• Keep the fuel-dispenser 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.
• Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious
injury and illness.
– Avoid prolonged breathing of vapors.
– Keep your hands and face away from the nozzle and the fuel-tank opening.
– Keep fuel away from your eyes and skin.
• Clean up any spilled fuel.
• Do not store the machine or fuel container where there is an open flame, spark, or pilot
light, such as on a water heater or on other appliances.
• Do not operate the machine without the entire exhaust system in place and in proper
working condition.

During Operation
During Operation Safety
• The owner/operator can prevent and is responsible for accidents that may cause
personal injury or property damage.
• Use your full attention while operating the machine. Do not engage in any activity that
causes distractions; otherwise, injury or property damage may occur.
• Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.
• Do not operate the machine unless all guards and safety devices, such as the deflectors
and the entire grass catcher, are in place and functioning properly. Replace worn or
deteriorated parts with genuine Spartan parts when necessary.
• Operating engine parts, especially the muffler, can become extremely hot. Severe burns
can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire. Keep
the engine area free from debris and excessive oil and grease.
• Operate the engine only in well-ventilated areas. Exhaust gases contain carbon
monoxide, which is lethal if inhaled.
• Operate the machine only in good visibility and appropriate weather conditions. Do not
operate the machine when there is the risk of lightning.
• Start the engine with your feet well away from the blades.
• Keep your hands and feet away from moving parts. Keep clear of the discharge opening.
• Keep away from holes, ruts, bumps, rocks, and other hazards. Use care when
approaching blind corners, shrubs, trees, tall grass or other objects that may hide
obstacles or obscure your view.
• Do not mow with the discharge deflector raised, removed, or altered unless there is a
grass-collection system or mulch kit in place and working properly.
• Do not mow in reverse unless it is absolutely necessary. Always look down and behind
you before moving the machine in reverse.
• Stop the blades whenever you are not mowing. Slow down the machine, and use caution
when crossing surfaces other than grass or when transporting the machine to and from
the operating area.
• Be aware of the mower discharge path and direct the discharge away from others. Avoid
discharging material against a wall or obstruction because the material may ricochet
back toward you.
• If the machine strikes an object or starts to vibrate, immediately shut off the engine,
remove the key, and wait for all moving parts to stop before examining the machine for
damage. Make all necessary repairs before resuming operation.
• Slow down and use caution when making turns and crossing roads and sidewalks with
the machine. Always yield the right-of-way.
• Never leave a running machine unattended.
• Before you leave the operating position, do the following:
– Park the machine on a level surface.
– Disengage the power takeoff and lower the attachments.

• The ROPS is an integral safety device. Do not remove any of the ROPS components
from the machine.
• Ensure that the seat belt is attached and that you can release it quickly in an emergency.
• Keep the roll bar in the fully raised and locked position and always wear your seat belt
whenever the roll bar is up.
• Check carefully for overhead objects before you drive under them, and do not contact
them.
• Replace damaged ROPS components. Do not repair or alter them.
• There is no rollover protection when the roll bar is down.
• Wheels dropping over edges, over steep banks, or into water can cause a rollover, which
may result in serious injury or death.
• Do not wear the seat belt when the roll bar is down.
• Lower the roll bar only when absolutely necessary; raise it as soon as clearance permits.
• In the event of a rollover, take the machine to an Authorized Service Dealer to inspect the
ROPS.
• Use only accessories and attachments for the ROPS approved by Spartan Mowers.
Slope Safety
• Slopes are a major factor related to loss of control and rollover accidents, which can
result in severe injury or death. The operator is responsible for safe slope operation.
3473-292B Page 4–10 Operation: During Operation
During Operation Safety (continued)
Operating the machine on any slope requires extra caution. Before using the machine on
a slope, do the following:
– Review and understand the slope instructions in the manual and on the machine.
– Use an angle indicator to determine the approximate slope angle of the area.
– Never operate on slopes greater than 15°.
– Evaluate the site conditions of the day to determine if the slope is safe for machine
operation. Use common sense and good judgment when performing this evaluation.
Changes in the terrain, such as moisture, can quickly affect the operation of the
machine on a slope.
• Identify hazards at the base of the slope. Do not operate the machine near drop-offs,
ditches, embankments, water, or other hazards. The machine could suddenly roll over if
a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width
of the machine) between the machine and any hazard. Use a walk-behind machine or a
hand trimmer to mow the grass in these areas.
G221745s
Safe Zone—use the machine
here on slopes less than 15° or flat
areas.
Danger Zone—use a walk-
behind mower and/or a hand
trimmer on slopes greater than 15°
and near drop-offs or water.
Water
W = Width of the machine
Keep a safe distance (twice the
width of the machine) between the
machine and any hazard.
• Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden
changes in speed or direction; turn slowly and gradually.
• Do not operate a machine under any conditions where traction, steering, or stability is in
question. Be aware that operating the machine on wet grass, across slopes, or downhill
may cause the machine to lose traction. Loss of traction to the drive wheels may result in
sliding and a loss of braking and steering. The machine can slide even if the drive wheels
are stopped.
• Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden
hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
• Use extra care while operating with accessories or attachments, such as grass-collection
systems. These can change the stability of the machine and cause a loss of control.
Follow directions for counterweights.
• If possible, keep the deck lowered to the ground while operating on slopes. Raising the
deck while operating on slopes can cause the machine to become unstable.

• Do not attach towed equipment except at the hitch point.
• Do not use the machine as a towing vehicle unless it has a hitch installed.
• Do not exceed the maximum gross towing weight.
• Never allow children or others near the towed equipment.
• On slopes, the weight of the towed equipment may cause loss of traction, increased risk
of rollover, and loss of control. Reduce the towed weight and slow down.
• The stopping distance may increase with the weight of a towed load. Travel slowly and
allow extra distance to stop.
• Make wide turns to keep the attachment clear of the machine.

Driving the Machine
CAUTION
Positioning one lever too far in front of the other causes the machine to spin very
rapidly. As a result, you may lose control of the machine, causing personal injury to
you and damage to the machine.
Slow down the machine before making sharp turns.
The drive wheels turn independently, powered by motors on each axle. You can turn 1 side
in reverse while you turn the other forward, causing the machine to spin rather than turn.
This greatly improves the machine maneuverability but may require some time for you to
adapt to how it moves.

Operating the PTO Switch
DANGER
The rotating blades under the mower deck are dangerous. Blade contact will cause
serious injury or death.
Do not put your hands or feet under the mower or mower deck when the blades are
engaged.
DANGER
An uncovered discharge opening allows objects to be thrown toward you or
bystanders. Also, contact with the blade could occur. Thrown objects or blade
contact will cause serious injury or death.
Do not operate the mower with the discharge deflector raised, removed, or altered
unless a grass collection system or mulch kit is in place and working properly.
The PTO switch starts and stops the mower blades and any powered attachments.
1. Increase the throttle to full throttle.
2. Engage the PTO switch.
Note: You may hear a squealing noise as the clutch plates engage. This is normal.
3. Mow as desired.
4. Disengage the PTO switch after mowing.
Side Discharge
The hinged grass deflector disperses clippings to the side and down toward the turf.
DANGER
Without the grass deflector, discharge cover, or complete grass catcher assembly
mounted in place, you and bystanders are exposed to blade contact and thrown
debris. Contact with rotating mower blade(s) and thrown debris will cause injury or
death.
• Do not remove the grass deflector from the machine, because the grass deflector
routes material down toward the turf. If the grass deflector is ever damaged,
replace it immediately.
• Never try to clear the discharge area or mower blades unless the power takeoff
(PTO) is off. Shut off the machine.

Operating Tips
Maximize Air Circulation
For best mowing and maximum air circulation, operate the machine with the throttle in the
F
AST position. Air circulation is required to thoroughly cut grass clippings, so do not set the
height-of-cut so low as to totally surround the mower deck in uncut grass. Always try to have
1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower
deck.
Avoid Cutting Too Low
When mowing uneven ground, raise the cutting height to slightly higher than normal to avoid
scalping the turf. However, the cutting height used in the past is generally the best one to
use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn
twice to ensure an acceptable quality of cut.
Cut a Third of the Grass Blade
It is best to cut only about a third of the grass blade. Cutting more than that is not
recommended unless grass is sparse, or it is late fall when grass grows more slowly.
Alternate the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse
clippings, which enhances decomposition and fertilization.
3473-292B Page 4–18 Operation: During Operation
Operating Tips (continued)
Mowing Frequency
Grass grows at different rates at different times of the year. To maintain the same cutting
height, mow more often in early spring. As the grass growth rate slows in mid summer, mow
less frequently. If you cannot mow for an extended period, first mow at a high cutting height,
then mow again 2 days later at a lower height setting.
Mow at Slower Ground Speeds
In certain conditions, mowing at a slower ground speed can improve cut quality.
Avoid Grass Clumps
If you must stop driving forward while mowing, a clump of grass clippings may drop onto
your lawn. To avoid this, move onto a previously cut area with the blades engaged or
disengage the mower deck while moving forward.
Keep the Underside of the Mower Deck Clean
Clean clippings and dirt from the underside of the mower deck after each use. Grass and dirt
build-up will eventually decrease the cutting quality.
Maintain the Blades
Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly
without tearing or shredding the grass blades. Tearing and shredding turns grass brown at
the edges, which slows growth and increases the chance of disease. Check the mower
blades after each use for sharpness, and for any wear or damage. File down any nicks and
sharpen the blades as necessary. If a blade is damaged or worn, replace it.
After Operation
