BELT TENSION ADJUSTMENT & REPLACEMENT
Shut the engine off first!
PLUG WiRE, and then remove the belt cover.
With the mower deck in the #5 height position and the
blade in the ON position, check the distance between
the inside surfaces of the belt as shown in FIG. 9. The
belt tension is adjusted by changing the "distance"
between the front axle and the rear case. Remove the
shoulder bolt (Y) (with the two metal spacers) from the
main channel tab (X) and pull the front assembly
FORWARD, increasing the belt tension until the correct
amount is achieved. Then remove one or more spacers
(as needed) from the hardware bag and align the
spacer(s) behind main channel tab (X) and over the tube
below it. Insert the shoulder bolt (without the two metal
spacers) through the matching holes in spacer(s) and
tab (X), and screw it into the front of the rear case -
securely tighten! Refer to FIG. 8.
If the belt becomes frayed, cracked, or worn, replace it
as follows: Remove the BELT COVER, then cut and
remove the old belt. To irtstall a new belt, close the fuel
cap (10-C) valve. Stand the mower on the REAR
BUMPER (14-C), shift into NEUTRAL, and work the belt
between discs, then shift into #5 speed and push belt
over edge of engine drive disc. Work belt into the
groove of the drive disc, then position other end in
pulleys on mower deck as follows: Loosen or remove
the idler pulley, loop the belt around spindle pulley as
shown in FIG. 9 and work belt between restrictor and
idler puller. Make sure locking tab on restrictor is
engaged in idler arm before securing idler arm nut and
bolt. Be sure the belt is inside all belt guides. Check
and adjust belt tension as needed before reinstalling the
BELT COVER.
BLADE BRAKE ADJUSTMENT |
As the brake band wears, the BLADE lever will gradually
stop further rearward in the slot erf the BELT COVER.
Blade brake adjustment is required when the lever stops
more than 1/4" behind the latch plate. Refer to FIG. 10.
The adjusting poirrf is shown in FIG. 11. With the
engine STOPPED, the adjustment is made as follows:
; ' I
STEP 1: Lower cutting deck and remove the BELT
COVER.
STEP 2: While holding the BLADE lever firmly in
the rearward position, loosen the jam-nut on the end
of the eye bolt (refer to FIG. 11).
STEP 3: Move the BLADE lever to the ON position,
press the BLADE pedals down and hold, then turn
the T-nut on end of eye bolt (clockwise) several
complete turns. Make sure tab on T-nut is positioned
vertically to fit over the anchor.
STEP 4: Release the BLADE pedals to allow the
BLADE lever to move to the OFF position, then
depress the BLADE pedals again and check the
clearance between forward edge of the BLADE
lever and the rear edge of the latch plate which
should be less than 1/4" (FIG. 10). Repeat the pro¬
cedure in step 2 if needed to obtain correct
clearance. When correct, hold the BLADE lever i
rearward and turn the jam-nut tight against the T-nut „ g, _
to lock in new position. Reinstall BELT COVER. t
After "distance" has been changed, check operation
of the clutch/brake pedal and readjust the brake con¬
trol cable, Lf needed , for proper traction and braking.
