Bad Boy maverick 4800 Owner's, Service & Parts Manual - page 30
The large turn buckles on the front of the deck only affect the
pitch of the deck or the level from front to back.
The deck spring tension is critical. If the tension is too high,
premature failure of the deck belt and blade spindles can
occur. If the tension is too low, the belt can ‘jump off’ or slip
on the pulleys. This results in reduced cut quality and early
belt failure. With the deck up, the spring coil gap should be
about .025˝ - .030˝ (about the thickness of a credit card).
Spring tension adjustments can be made by sliding the bolt
shown above forward or backward in the slot of the deck. Belt
tension should be 50- 55 lbs with the deck at its highest
setting.
The blade in the foreground (see photo) was utilized long
after replacement was required. In addition to a decline
in cut quality, failure to replace a worn or damaged blade
creates a major safety hazard. Bad Boy recommends that
blade sharpening be performed by a professional.
To change blades, it may be easier to use a piece of wood to
keep the blade from turning so that the bolt can be loosened.
Bolts used have right-handed threads. Re-torque the blade
bolts to 90-110 lbs. The blade spindles contain a sealed ball
bearing inside the top and bottom of the spindle. The
bearings are replaceable for a more cost effective repair.

SECTION 4: ELECTRICAL SYSTEM
This mower is equipped with three protective fuses:
a 25 amp main fuse (pictured to the right), a 10 amp
clutch fuse (blade engagement) and a 15 amp linear
actuator fuse (deck lift). The main fuse is located on
the left side of the unit; by the starter solenoid.
The clutch fuse is located just underneath the control
panel along with the linear actuator fuse. You will need
to remove the four screws that hold the control panel to the
tank using a 3mm or a 1/8” hex wrench.
A blown fuse usually indicates a problem
within the electrical system or an electrical
component. Ensure the battery terminals
are tightly fastened. Never replace a fuse with one of
a higher amperage rating or
‘bypass’ a fuse in any way. Doing so creates a
significant fire hazard and can cause severe damage
to the mower’s electrical components. If a fuse is
repeatedly blowing, contact your Bad Boy dealer.
On most models, the red wire coming out of the
engine is the charging wire from the alternator.
Check for 13.6 - 14.2 volts dc at this wire with engine
at full throttle.
If you are having issues starting your mower
ensure the signal wire is connected to your starter
solenoid.
