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. Belt tension
should be 50- 55 lbs with the deck at its highest setting. Belt
tension adjustments can be made by sliding the bolt (notice
picture) forward or backward in the slot of the deck.
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 two sealed ball bearings inside the top and bottom
of the spindle. The bearings are replaceable for a more cost
effective repair.
