Mower Drive Belt Adjustment
(For 28” & 30” Decks Only)
1. Remove the mower drive belt cover. Refer to the sec-
tion entitled “CHECK MOWER DRIVE BELT”.
2. Move the blade lever up and over to the “ON” position.
3. Place the deck cutting height lever in the third position
(middle notch). Measure the belt spacing
(B, Figure 36)
between the idler pulley
(A)
and belt. The distance
should measure 1-1/4” but no less than 1”.
4. If the distance is less than 1”, adjust belt tension:
Move the blade lever to the “OFF” position.
Loosen the hardware
(A, Figure 37)
that secures
the clamp that anchors the front frame assembly
(B)
to the rear main case.
Pull the front frame forward until the belt spacing,
with the blade lever “ON”, measures 1-1/4”.
Retighten the hardware that secures the clamp.
Make sure the hardware is tightened securely.
IMPORTANT:
The SNAPPER Rear Engine Rider Models with
33” decks do not require belt tension adjustment. But, if the
front frame assembly clamp is loosened for any reason,
recheck the belt spacing between the idler pulley and belt.
With the blade lever in the “ON” position, the distance
should measure 1-3/4”.
5. When belt adjustment is complete, it will be necessary
to check Clutch/Brake Cable slack. Disengage the park-
ing brake and allow the pedal
(A, Figure 38)
to remain
in the engaged wheel drive (Up) position. The
clutch/brake cable should have approximately 3/16” of
slack. If the cable does not have slack adjustment of
cable must be performed:
Peel back the rubber clutch/brake pedal pad and
push one ferrule
(B)
through the hole
(C)
in the
pedal to attain slack in the cable.
Recheck the cable for the approximate 3/16” of
slack. Replace the pedal pad when adjustment is
complete.
IMPORTANT:
Too much slack may cause improper clutching,
and braking could be affected. Too little slack may cause
improper clutch function. Recheck the service brake/park
brake and readjust if necessary. Refer to the section entitled
“SERVICE BRAKE/PARK BRAKE ADJUSTMENT”.
