Short Right Hand Deck Belt Replacement
(61" Mower Deck)
NOTICE To avoid damaging belts, do not pry over pulleys.
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.
2.
Lower the mower deck to it’s lowest cutting position and
remove the mower deck guards and floor pan to gain access
to the mower deck drive belts.

WARNING
Use extreme caution when rotating the idler arm, due to the
increased tension in the spring as the idler arm is being
rotated. Injury may result if the idler arm is prematurely
released while the spring is under tension.
4.
Rotate the spindle drive idler arm (A, Figure 71) clockwise,
which will relieve tension on the belt exerted from the idler
arm. Remove the belt from the rear idler pulley (B) and then
the right hand spindle pulley (C). Carefully release the
tension on the spindle drive idler arm.

5.
Remove the spring anchor hardware (D) that anchors the
idler arm spring (E) to the mower deck.

Remove the old short right hand belt (F) from the front idler
pulley (G) and the center spindle pulley (H).
7.
Install the new short right hand belt onto the center spindle
pulley and the front idler pulley.
8.
Re-connect the idler arm spring. Install the 3/8 washer and
then the spacer onto the shaft of the 3/8 bolt. Install the
hook of the idler arm spring around the body of the spacer
and then install the bolt into the spring anchor tab and then
secure with the 3/8 nylock flange nut.
9.
Rotate the spindle drive idler arm clockwise, which will
relieve tension on the belt exerted from the idler arm.
Re-install the belt on the right hand spindle pulley and then
the rear idler pulley. Make sure that the V-side of the belt
runs in grooves of all four pulleys. Carefully release the
tension on the spindle drive idler arm.
10. Set the mower deck to the 3-1/2" (8,9 cm) cutting position.
11. Measure the coil-to-coil length (I) of the idler arm spring.
The measurement should equal 6-1/8" (15,6 cm). If not,
loosen the jam nut (J) on the carriage bolt (K) and the 3/8"
nut (L) that secures the rear idler pulley (B) to the deck.
This will allow the rear idler pulley to move in it's adjustment
slot.
12. Turn the adjustment nut (M) until the measurement is
achieved. Tighten the jam nut and the 3/8" nut that secures
the rear idler pulley to the deck.
