balanced similar to conventional blades, but a
straight-edge should be used to confirm that the
blades are straight out. If the blades are partially
folded during balance checking, the results will
be thrown-off.

2.14. On installation, apply thread locking compound

such as Loctite 262 (red) to the threads, and
tighten the nut to a torque of 100-120 ft-lbs (114-
136 Nm).

2.15. Install the belt covers and reconnect the battery.

Precautions:

Disable the engine while working on the cutting
deck: Disconnect the sparkplug leads, discon-
nect the negative battery cable, and/or remove
the key from the key switch.

Allow the engine to cool thoroughly before work-

Protect hands while working on sharp objects
like blades using gloves or rags.

Apply the parking brake while working on the
mower.

tension from the belt tensioner pulley, and roll
the belt off of the pulley, allowing the tensioner
pulley to slip beneath the belt. See Figure 3.5.

With the tension relieved, connect a 1 1/8”
wrench to the bolt at the top of the stack pulley.
Pass the wrench beneath the belt to reach the
bolt. See Figure 3.6.

Draw the wrench forward to force the belt over
the top of the pulley.
