BELT TENSION ADJUSTMENT & REPLACEMENT
Shut the engine off first! DiSCONNECT THE SPARK
PLUG WIRE, and then remove the belt cover.
With the mower deck in the #5 height position and the
biade 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.
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.
Refer to the Brake section.
If the belt becomes frayed, cracked, or worn, replace it
as follows; Remove the BELT COVER, then cut and
remove the old belt. To install a new belt, close the fuel
cap {^6-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 aixl 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 reinstailing the
BELT COVER.
BLADE BRAKE ADJUSTMENT
As the brake band wears, the BLADE lever will
gradually stop further rearward in the slot of the
BELT COVER. BRAKE adjustment is required when
the lever stops 1/2" from the top of the belt cover.
The adjusting point is shown in FIG. 11. With the
SOgiDi stggp^, the adjustment is made as follows:
STEP 1; Lower cutting deck and remove the BELT
COVER.
STEP 2; Move the BLADE lever to the ON position.
Press the BLADE pedals down and hold, then turn the
nut on the end of the eye bolt (clockwise) several
complete turns. Make sure the nut lock is positbned
properly to fit over the anchor.
STEP 3; Release the BLADE pedals to allow the BLADE
lever to move to the OFF position. Then depress the
BLADE pedais again and check the ciearance between
the forward edge of the BLADE lever and the rear edge
of the latch plate. There should be less than 1/4“
clearance (see FIG. 10). Repeat the procedure in step 2
if needed, to obtain the correct clearance. Reinstall the
BELT COVER.
