SECTION 2: MOWER OPERATION
Never allow untrained people to operate this machine. It is the owner’s responsibility to get training and
see to it that anyone who has permission to use your machine receives the proper training.
Do not mow around people. The factory discharge chute is designed to deflect debris downward, but it
could be possible for debris to be thrown in a way that can cause damage to people or property.
Seek additional training when possible to learn more about safety techniques and practices.
SAFETY PRECAUTIONS

SECTION 3: MOWER OPERATION
Never operate the machine with faulty equipment. Always be alert of sudden changes
in landscape, as the mower will react differently on slopes or embankments than it will
on flat surfaces. Never operate the mower with the discharge chute open. Do not cross
terrain, other than grass, with blades turning. This could cause damage to property or
bystanders.
3.1 Place parking brake in up position
3.2 Drive arms must be in the “open˝ position. While sitting on the machine, each arm is
positioned away from the operator, to the right and left. Drive arms will lock into place and
must be in this position to start machine.
3.3 Put PTO switch in the OFF position.
3.4 If your machine has been equipped with a ROPS (Roll Over Protection System) then you
must fasten seatbelt.
3.5 If machine has not been started recently, engage the choke.

motor oil On all Bad Boy commercial models, the hydraulic oil and filters need to be initially
changed when mower has reached 50 hours of usage. Each subsequent changing of the
hydraulic oil and filters needs to occur 500 hours or once a year. The required hydraulic oil is
20W50 motor oil.
SECTION 7: TROUBLESHOOTING
7.1 Q: How do I sharpen my blades?
7.1 A: We recommend that sharpening be done by an authorized Bad Boy dealer.
7.2 Q: How should I prepare my Bad Boy Mower for the off season?
7.2 A: When preparing for any down period of 90 days or more, the most important thing is
proper fuel preparation. Use a fuel stabilizer in your final tank of fuel or run dry. Choke and
repeatedly crank engine until it will not start. This will decrease the potential for varnish or
gum deposits forming in your system. Also, make sure your machine has plenty of antifreeze.
You can get an antifreeze tester at your local hardware store to ensure your machine is ready
for winter.
7.3 Q: How do I prevent an uneven cutting pattern and increase the quality of cut?
7.3 A: Check tire pressure, check blade sharpness (replace blades or sharpen at least once
per year or when needed), make sure blades are tightened properly, check spring and belt
tension, check the underside of the deck to ensure the mower deck is free of grass build-up
and debris, make sure your machine is at full throttle, and vary your mowing pattern each
time you cut your grass.
7.4 Q: What should I do if my mower won’t start?
7.4 A: Check battery charge and connection (grounds), check your fuel (make sure fuel is less
than 30 days old and contains no water), make sure your spark plug is in good condition
and spark plug wire is attached, and make sure air filter is clean (a dirty filter makes it more
difficult for the engine to draw air). Check for broken wires or bad connections.
7.5 Q: What should I do if the blades won’t engage?
7.5 A: Make sure the safety switch is plugged in on the bottom of seat. Check the underside of
the PTO engager to ensure the plug is secure at switch.
7.6 Q: What should I do if mower arms are in neutral position and mower still creeps?
7.6 A: Contact authorized Bad Boy Mower Dealer.
PAGE 9
7.7 Q: What is the difference between a liquid-cooled engine and an air cooled-engine?
7.7 A: A liquid-cooled engine gives you a constant operating temperature which will increase
fuel economy, decrease oil breakdown, and may last up to 50% longer. In addition, a cooler
engine also means a cooler operator because the cooling fan draws hot air through the
radiator, past the engine and away from the operator. An air-cooled engine is much simpler
with fewer working parts which means a lower purchase price and less maintenance
7.8 Q: What type of fuel is recommended for my mower?
7.8 A: We recommend that you use a name brand fuel to ensure quality. Use fuel with an octane
rating near 87. Higher octane fuels offer no benefit.
7.9 Q: Does the Bad Boy warranty cover multiple owners?
7.9 A: The warranty applies only the original registered owner and is non-transferable.
7.10 Q: Do you offer touch-up paint for your mowers?
7.10 A: Touch-up paint is available. Contact your local dealer for more information.
7.11 Q: On average, how long should a Bad Boy mower last?
7.11 A: Maintenance, mowing conditions, temperature, and hours of operations play a huge role
in the life of a mower. However, Bad Boy Mowers are without a doubt the strongest, most
durable zero-turn mower available. With proper care, your Bad Boy will deliver many years
of reliability, productivity, and comfort.
7.12 Q: How durable is the electric deck lift?
7.12 A: The actuator which controls the deck height is designed for moving loads of up to 1000
pounds and has a static holding capability which exceeds 3,000 pounds. Our ¼˝ deck weighs
approximately 250 pounds which is only 25% of working capability.
SECTION 8: CONTROLS
8.1 Ignition Switch—Bad Boy Mowers have a three position ignition switch: off, run, and start.
With key inserted, rotate it clockwise to START position and release key when engine starts,
and switch will automatically return to he RUN position.
8.2 Throttle Control—A cable is connected to the engine throttle for controlling engine speed.
Move lever forward to increase engine rpm, move lever backward to decrease engine rpm.
