SECTION 6: CUTTING DECK

DECK BELT REMOVAL:

1)Remove ignition key.
2) Raise the deck to its highest position.
3) Remove the right pulley cover.
4)While lifting up on the belt (as shown in the

photograph), rotate the pulley until the belt
is free of the pulley. Exercise caution while
performing this step as fingers can easily
become caught between the belt and
pulley.

DECK BELT INSTALLATION:

1) Follow steps 1 and 2 from the deck

removal section.

2) Take off both pulley covers and route

the belt by following the belt route 
sticker.

3) The easiest way to finish running the

belt is routing the belt through the deck
pulleys and carefully slipping the belt
onto the clutch in the rear of the engine.

4) Verify that the belt is routed properly as

improper routing can damage the
spindles as well as the engine.

1) Start on a flat level surface and set

the air pressure in all four tires to 12
psi.

2) Get 2 2x4s and make sure that the wider

sides are similar length.

3) Take off the foot pedal and raise the floor

plate.

4) Lower the deck onto the 2x4s and

pin the deck into its top available height.
Remove the dampener that attaches to the
actuator bar using two ½” wrenches.

5) Now ensure that the deck is level left to

right and has a pitch down of ¼” from the
back to the front. This can be done by
adjusting the tabs on the deck.

6) Loosen the bolts on the back of the deck

using two ¾” wrenches until the deck
hanger is resting against the bolt.

7) Adjust the front deck hanger until there is

¼” gap between the deck hanger and the
bolt that it rests on.

8) Reattach the dampener to the actuator bar.
9) Place the floorplate down and place the foot

pedal back on and you should be ready to
mow.

LEVELING THE DECK:

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. for a 54” deck and 65-70 lbs. for a 61” and 
70-75 lbs for a 72” deck, 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.

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.   

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.
