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
1. 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.
2. 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.
3. 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.
4. Check the mower blades for any damage or abnormal wear and replace in sets so that they are balanced.
5. Check the tire pressure on all four (4) tires. See page 12 for details.
6. Check all belts for proper wear and correct tension. See pages 14-16 for details.
7. Check engine oil and air filter as recommended in the engine manufacturer’s operators manual.

OPERATION OF EQUIPMENT
8. DANGER: GASOLINE IS HIGHLY FLAMMABLE AND EXPLOSIVE. DO NOT ADD FUEL WHILE
THE 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 IFTHE .FUEL IS SPILLED, DO NOT START THE ENGINE.
MANUALLY PUSH THE MOWER AWAY FROM THE SPILL AND IMMEDIATELY WIPE UP.
9. DANGER: GASES EMITTED BY A CHARGING BATTERY ARE EXPLOSIVE. KEEP HEAT,
SPARKS AND OPEN FLAMES AWAY FROM A CHARGING BATTERY.
10. 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.
11. Mow only in daylight.
12. Make sure the mower is in neutral and the blades are disengaged before attempting to start the engine.
13. 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.
14. Avoid steep slopes and use extreme caution when changing directions or speed when operating on a slope.
15. 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.
16. 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.
17. Never operate the mower with defective guards, shields, or without the safety devices securely mounted in
place.
18. Never direct discharge of material toward bystanders or allow anyone near the mower while in operation.
19. Do not change the engine governor settings or over-speed the engine.
20. Always stop the engine whenever you leave the mower, even for a moment.
21. 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.
22. 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.
23. 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.

Blades should be inspected on a daily basis for nicks, bends, and or excessive wear. If the blades are worn,
cracked bent, or damaged, replace with a new blade immediately before using the mower. Use only
genuine Bradley replacement blades since substitute blades may not meet Bradley mowers specifications
and may be dangerous.
When sharpening the blades, sharpen only the cutting edges and try to maintain the original angle of the
blade. Do not make the cutting edge ‘razor sharp’and remove the same amount from each side of the
blade so that balance is maintained.
Cleaning the Mower
It is recommended that the mower be cleaned in a daily basis. Excessive accumulation of dirt, debris, oil,
etc. causes premature wear on the components and may present a potential safety hazard.
