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.
3.6  Make sure nothing is under or around machine.
3.7  Place key in ignition and turn.
3.8  Once machine is started, disengage the choke.
3.9  Increase RPM by sliding the throttle to fast position, toward the rabbit.
3.10  Owners must become familiar with the controls before operating a zero-turn radius vehicle.
3.11  Start slowly and build your skill level. Have ample practice before using the machine at full 

capabilities.

3.12  Be comfortable with machine before engaging blades. Know what each component controls 

before using machine.

3.13  Your mower will perform differently on an incline /decline. Be cautious, slow down, and do 

not make any sudden jerking movements with control arms. The machine could lose traction 
on a decline or tip backwards on an incline. 

3.14  Once you become comfortable with your Bad Boy Mower you will notice your overall mowing 

time will decrease. 

Avoid operating your mower on side hills of over 5 degrees,

inclines of over 10 degrees,

and declines of over 15 degrees.
