1. Park the unit on a smooth level surface such as a
concrete floor. Disengage the PTO, engage the parking
brake, turn the ignition switch to OFF, and remove the
ignition key.

WARNING
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring
as the idler arm is being rotated. Injury may result if the
breaker bar is prematurely released while the spring is
under tension.
3. Using a 1/2" breaker bar (A, Figure 70) place the square
end in the opening in the PTO clutch drive idler arm (B)
and rotate the idler arm clockwise, which will relieve
tension on the belt exerted from the idler arm. Remove
the belt from the left hand side spindle pulley (C).
Carefully release the tension on the breaker bar.
