before performing the following steps.
• Locate the fixed v-idler pulley found on the left
underside of the frame. See Figure 17.

gently move it toward the left frame rail allowing it to
unseat itself from the fixed v-idler. See Figure 17.
• Pivot the double-idler bracket forward slightly
before removing the idler extension spring from the
stud and the double-idler bracket itself. Do not
discard the spring.
• Roll the drive belt out from around both the v-idler
pulley and the flat idler pulley found on the double-
idler bracket.
• Carefully unplug the tractor's wire harness from the
connector on the electric PTO clutch.
• Remove the hex bolt from the center of the electric
PTO clutch and gently lower it off the engine
crankshaft. Be careful not to lose any washers or
spacers which may be on top of the electric PTO
