Although it is fastened with a multi-position anchor, this is
not an adjustment point.
Do NOT attempt to adjust the spring length or lifting
performance will be compromised.

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 a 1/2" breaker bar (B) place the square end in
the opening in the idler arm (C) and rotate the idler arm
clockwise, which will relieve tension on the belt exerted
from the idler arm. Remove the belt from the left hand
side spindle pulley (D). Carefully release the tension on
the breaker bar.
4. Pull the length of the belt removed from the left hand
spindle pulley towards the center of the deck and remove
the belt from the belt guide (E) installed on the adjustable
idler pulley (F). To remove the belt from the belt guide,
start with the leg of the belt between the adjustable idler
pulley and the PTO clutch pulley (G) and raise the belt up
and out of the belt guide.
5. Remove the old belt from the PTO clutch pulley, front
stationary idler pulleys (H), rear stationary idler pulley (I),
and the remaining spindle pulleys (J).
6. Install the new belt onto the right hand side and the
center spindle pulleys and the PTO clutch pulley. Make
sure that the V-side of the belt runs in the pulley grooves
and that the belt is correctly routed through the PTO
clutch belt guide (K) and that the back side of the belt
contacts the faces of the front stationary idler pulleys and
the rear stationary idler pulley.
7. Install the belt into the belt guide installed on the
adjustable idler pulley. To install the belt into the belt
guide, start with the leg of the belt between the adjustable
idler pulley and the PTO clutch pulley and lower the belt
down and into the belt guide. Pull the length of the belt
towards the left hand spindle pulley. Carefully release the
tension on the breaker bar.
8. Verify that the V-side of the belt runs in the grooves
of the right hand side and center spindle pulleys and
the PTO clutch pulley. Verify that the back side of the
pulley contacts the face of the adjustable idler pulley,
front stationary idler pulleys, and the rear stationary idler
pulley. Verify that the belt is correctly routed through the
belt guides.
9. Rotate the idler arm clockwise and install the belt on the
left hand spindle pulley.
10. Carefully release the tension on the breaker bar.
11. Measure the coil-to-coil length (A, Figure 69) of the
mower deck belt tensioning spring (B). The measurement
should equal 12-1/2" (32 cm). If not, loosen the jam nut
(C) on the eye bolt (D).
