Mower Deck Preparation

Remove the Mower Deck Spindle Belt
The mower deck is equipped with an idler arm (A,
Figure 14) which is fastened to a spring (B). Rotating
the idler arm in a direction that lengthens the spring
will relieve the tension on the spindle belt (C). This will
allow you to remove the belt from the spindle pulley.
1. Use a 1/2" breaker bar, place the square end in
the square hole located in the idler arm.
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.
2. Carefully rotate the idler arm either clockwise or
counter-clockwise so that it lengthens the idler
spring.
3. Slide the drive belt over the edge of the rear
stationary idler pulley (D). Carefully release the
tension on the breaker bar.
4. Remove the belt from the right-hand (discharge
side) spindle pulley (E).
Remove the Mower Deck Spindle Pulley
1. Remove the 3/4-16 hex nut and 3/4" spring washer
(A & B, Figure 15) securing the spindle pulley (C)
to the spindle shaft. Use a 1" wrench on the flats
of the blade end of the spindle shaft to prevent the
shaft from spinning. Save the 1/4" key (D).
