SAFETY INFORMATION
Read This Manual Carefully and Thoroughly Before Operating Your Mower!
1. Carefully and thoroughly read the owner's manual. Allow adequate time to fully understand the
controls and operation of the equipment. Never allow anyone to operate the mower that has not read
and fully understood the owner's manual.
2. Never allow anyone to operate the mower who is not old enough, large enough, and strong enough to
safely handle the machine.
3. Do not carry passengers. Avoid mowing while people, especially children, and pets, are nearby since
rotating blades can throw rocks and other items with enough force to cause serious injury.
BEFORE USING EQUIPMENT
OPERATOR
Wear protective clothing while mowing. Long trousers and safety glasses will help reduce the risk of
injury from thrown objects. It is recommended that steel toe shoes with aggressive soles or some other
type of substantial footwear be worn to help protect your feet and maintain traction on slopes or uneven
ground.
MOWING AREA
Thoroughly inspect the area where the equipment is to be used. Look for items such as stones, sticks,
bones, wire, and other foreign objects. When struck by the mower, these and other objects may become
projectiles that could lead to serious injury and/or death.
MOWER
For your safety and the long life of your mower, always inspect the mower before each use. Before
inspection, make sure the mower is on a flat and level surface, the blades are disengaged, the ignition
switch off with the key removed, and the spark plug wire is off of the spark plug(s) and hidden so that
accidental contact cannot be made.
GENERAL CONDITION
Walk around the mower looking for any fluid spills or leaks on or underneath the mower.
Remove any and all excessive debris, dirt, and/or fluids.
Look for signs of damage or excessive wear. Check the tightness of all nuts, bolts, pins, and
screws. Tighten any that may be loose and replace any that may have been lost during use.
Be sure the safety interlock controls are operating properly so that the engine cannot be started
unless the ground speed control lever is in neutral and the blades disengaged.
Check the mower blades for any damage or abnormal wear and replace in sets so that they are
balanced.
Check the mower cutting height to assure a high quality and even cut.
Check the tire pressure on all four (4) tires.
Check all belts for proper wear and correct tension.
Check engine oil and air filter as recommended in the engine manufacturer's operators manual.

OPERATION OF EQUIPMENT
1. DANGER: Gasoline is highly flammable and explosive. Do not add fuel while engine is running or is
hot. Keep open flames,sparks,and heat away from the fuel and store fuel in containers specifically
designed for that purpose.Add fuel outdoors only and if the fuel is spilled, Do not start the engine.
Manually push the mower away from the spill and immediately wipe up.
2. DANGER: Gases emitted by a charging battery are explosive.Keep heat,sparks and open flames
away from a charging battery.
3. Do not operate the engine in a confined space where dangerous carbon monoxide fumes can
collect. Carbon monoxide is odorless, tasteless, and can be fatal.
4. Mow only in daylight.
5. Make sure the mower is not in neutral and the blades are disengaged before attempting to start the
engine.
6. Do not stop or start suddenly when going uphill. Never use riding attachments on slopes since
there is an increased risk that they might roll over.
7. Avoid steep slopes and use extreme caution when changing directions or speed when operating on
a slope.
8. Be extremely careful when operating on a slope or when the grass is damp or wet. Reduced traction
could cause sliding. Never mow by pulling the mower back towards you as you might slip.
9. Watch for traffic when crossing surfaces other than grass (i.e. transporting), loading a trailer or
vehicle, or when the mower is not in use.
10. Never operate the mower with defective guards, shields, or without the safety devices securely
mounted in place.
11. Never direct discharge of material toward bystanders or allow anyone near the mower while in
operation.
12. Do not change the engine governor settings or over-speed the engine.
13. Always stop the engine whenever you leave the mower, even for a moment.
14. To help reduce the risk of a fire hazard, keep the engine and the area around the engine free of grass,
leaves, or any other type of foreign material.
15. Beware of cutting edges. Always wear gloves for safety when performing blade maintenance
activities. Beware on multiple blade units since the rotation of one blade may cause the rotation of
the other blades.
16. Keep body and hands away from pin holes or nozzles that eject hydraulic fluid since fluid escaping
under pressure may have sufficient force to penetrate skin and cause serious injury. If foreign fluid is
injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this
form of injury. Always use paper or cardboard and not hands to search for leaks.
