Snapper 11 Series - Clutch Adjustment; Cutting Blade Service

WHEEL BRAKE TEST & ADJUSTMENT ^ CLUTCH ADJUSTMENT
Test the wheel braking action at frequent intervals to
insure proper stopping in the event of possible
emergencies. Normally, the rider should stop from
FAST (top forward speed) within approximately three
feet after the CLUTCH/BRAKE pedal has been fully
depressed.
WARNING: Always disconnect the spark plug wire
and secure the end away from the plug before in¬
specting/servicing the rider/mower, to prevent un¬
intentional start-ups.
Adjustment is made by repositioning the yoke iift
spring, initiaily the spring is hooked through the #2
hole (second from end) in the ciutch iink - there are 4
holes. With the spring hooked in the #2 hoie, the
ciutch wiii have smooth action under normai ioads.
Hook the spring in #1 hoie to puli heavier loads, if
when releasing foot pressure on the
CLUTCH/BRAKE pedal (5-C), the rider tends to "hop"
rather than start forward or reverse motion
smoothly, hook the spring through hole #3 or #4 to
attain smoother starts.
Prior to making brake adjustment, check to see that
the mower belt is adjusted properly.
Stand the rider on its REAR BUMPER (14-C), engage
the PARKING BRAKE (13-C), shift the TRANSMiSSJON
SHIFT lever (17-C) to the REVERSE position, and
then check the distance between the driven disc's
rubber drive ring and the surface of the drive disc.
There should be between 1/16" and 1/8" clearance.
If the proper distance is not evident, the clutch/brake
cable needs to be adjusted. Release the parking
brake, rotate the clutch yoke to provide slack in the
cable, and then move 1 of the spacers (Y) through the
"keyhole" slot in the top of clutch arm (X) to the end
of cable. Re-engage the parking brake and again
check the clearance between the rubber ring and the
drive disc. Repeat this procedure until the proper
distance in achieved.
i i
To adjust the brake (with the parking brake on),
loosen both jam nuts (A) which secure the clut¬
ch/brake cable threaded tube (B) to the chain case
bracket as shown. Then, by screwing the two jam
nuts up or down, the tube can be moved to change
the distance the cable end is recessed INSIDE the
spring guide (tube), which is attached to the brake
lever. Adjust the threaded tube up or down until the
cable end is recessed between 3/16" to 7/16" from the
cotter pin. Retighten both jam nuts (A) against
bracket (C).

CUTTING BLADE SERVICE
BE CAREFUL: Avoid cutting yourself on a sharp
blade! Wear gloves to protect your hands while
handling the blade.
Check the blade at frequent intervals for proper
tighteness and operating condition. Replace if chip¬
ped, bent or notched. Sharpen if in otherwise good
conditlon-at an angle of 22-28 degrees inward about
2-f/2"from tips. Check blade for balance and correct
to prevent vibration. Install the blade with retaining
hardware as shown in FIG. 14 and tighten to torque
specified.
Check levelness (straightness) of the blade "TIPS".
Mark one (A) and the other (B). Scribe a mark on the
deck at the lip. By rotating the blade, measure the
distance "TIP" (A) and then "TIP" (B) each are from
the marked lip.
! ;
If there is a difference of more than 1/16" between
the two measurements, level the "TIPS" by loosen¬
ing the two jam nuts, and turn each of the two
jackscrews either clockwise or counter-clockwise
until the "TIPS" are within 1/16" of each other. Then
retighten the jam nuts against the blade bar.
NOTE: If after'inspection, the blade tips are found to
rotate closer to one point on deck lip, the lateral
position of spindle housing needs to be re-centered
by your Authorized SNAPPER Dealer.
