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.

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 60-65 lbs. with the
deck at its lowest setting.

Use a belt tension gauge to ensure the
proper tension. Your dealer or service
center will have a belt tension gauge or you
can buy one (Part Number 041-9999-00).

Blade Sharpening:

The blade on the top (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.

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.

BLADE REMOVAL:

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. Use a 15/16” socket and impact Drill, or a
wrench and an extension to gain more leverage. You
might need to put a ¾” wrench on top of the pulley bolt
to keep the blade from spinning.

Bolts used have right-

handed threads.
