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 the 1/2” breaker bar, place the square end in the
opening in the idler arm (B) and rotate the idler arm
clockwise
, which will relieve the tension on the belt
exerted from the idler arm.
4. Slide the belt over the edge of the left hand side double
spindle pulley (C). Carefully release the tension on the
breaker bar.
5. Remove the old belt and replace with a new one.
6. Install the belt onto the PTO clutch pulley (D), the front
stationary idler pulley (E), and the adjustable idler pulley
(F).
7. Carefully rotate the breaker bar
clockwise
and install the
belt on the left hand side double spindle pulley, making
sure that the V-side of the belt runs in the grooves of the
PTO clutch pulley, the front stationary idler pulley and the
double spindle pulley and that the back side of the belt
should contact the face of the adjustable idler pulley.
8. Carefully release the tension on the breaker bar.
Check / Adjust PTO Belt Tensioning Spring
Length (36" Mower Decks)
1. Set the mower deck to the 3-1/2" (8,89 cm) cutting height.
2. Measure the coil length (A, Figure 49) of the PTO drive
belt tensioning spring (B). The measurement should
