STEP 4: Check the clearance between the clutch cable and
clutch spring. NOTE: Clearance between spring and cable is
very important. Excessive clearance will cause drive system
NOT to operate when wheel drive control handle is
depressed. No clearance at all will cause mower to continue
to propelling itself when wheel drive control handle is
released to stop mower movement. Slide vinyl spring cover
(located at the end of clutch cable) up clutch cable to gain
access to the end of spring and cable loop. With wheel drive
control handle released, clearance between spring hook and
cable loop should be 1/16” to 1/8”. If clearance is more or
less than specified, unhook spring from clutch cable eye,
then adjust by turning inner spring in an opposite direction
than the outer spring. Rehook spring to clutch cable eye.
Slide vinyl cover over the spring when correct clearance is
reached. See Figure 11.

STEP 5: Driven disc to drive disc adjustment is set up
at the factory. In case driven disc may need adjustment,
proceed as follows:
A. Place speed control rod in the number six speed
position. See Figure 12.
FIGURE 12
B. Remove driven disc spring from driven disc
assembly as shown. Loosen connector hex-nut.
See Figure 13.
FIGURE 13
C. Slide driven disc assembly over until 1/8” from
outside edge of drive disc. Maintaining the 1/8”
measurement, remove any looseness from the
linkage. This can be done by holding the transfer rod
and applying pressure to the left (as viewed from
operators position), then retighten the connector hex
nut securely. See Figure 14. Move shift rod to the
number one speed position, then back to the number
six speed position. Recheck the 1/8” measurement
described previously. Reinstall driven disc spring to
driven disc assembly.
