3. Check the routing of the belt.
• 44" Mower Deck: Make sure that the V-side of the
deck drive belt runs in the grooves of the left and right
spindle pulleys (A & B, Figure 12 - exposed when
mower deck guards were removed) and the PTO
clutch pulley (E). Make sure that the back side of
the belt contacts the face of the rear stationary idler
pulley (F), and the adjustable idler pulley (G).
• 48" Mower Deck: Make sure that the V-side of the
deck drive belt runs in the grooves of the left and
right spindle pulleys (A & B, Figure 13 - exposed
when mower deck guards were removed), the center
spindle pulley (F) and the PTO clutch pulley (E).
Make sure that the back side of the belt contacts the
face of the front stationary idler pulley (G), the rear
8
stationary idler pulley (H), and the adjustable idler
pulley (I).
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. If the belt is not properly seated rotate the idler arm
(D, 12 and 13) counter-clockwise which will relieve the
tension on the belt exerted from the idler arm.
5. Re-seat the belt and carefully release the tension on the
idler arm.
6. Set the mower deck to the 3" (7,6 cm) cutting height.
7. Measure the coil-to-coil length of the belt tensioning
spring (A, Figure 14). The coil-to-coil measurement
(B) should equal 6" (15,2 cm). If the measurement is
not correct, the spring will need to be adjusted. If the
measurement is correct, skip to step #11.

8. Loosen the jam nut (C) on the spring anchor eye bolt (D).
9. Turn the adjustment nut (E) until the measurement
of 6" (15,2 cm) is achieved.
10. Tighten the jam nut.
11. Re-install the spindle covers and the floor pan.
12. Run the mower deck under no-load condition for about
five (5) minutes to break in the new belt.
