5.2.11 Shifter detent adjustment - Transmission shifter detent can be adjusted by adjusting
the setscrew on the back side of transmission located just behind the neutralstart
switch. Turn setscrew in (clockwise) to hold the transmission shifter more positively
in each gear and to increase the force on the lever required to shift gears.
Turn setscrew out (counterclockwise) to decrease force on lever required to shift
gears. Factory setting is to turn setscrew all the way in then back out 1-1/2 turns.
IMPORTANT
:
Screwing setscrew in too far will prevent the transmission from
shifting.
5.2.12 Blade safety switch.
a) Stop engine and remove spark plug wire(s).
b) With the blades disengaged and the bellcrank touching the engine deck,
adjust the blade safety switch (if needed) until the bellcrank depresses the
plunger by 1/4".
c) Be sure the bellcrank does not contact the switch body to prevent damage to
the switch.
d) Retighten switch mounting hardware.

IMPORTANT: When the handle height adjustment is changed, it will
be necessary to readjust the wheel drive and brake linkage (See
Sections 3.8.5 and 3.8.6).
5.2.14 Wheel drive spring tension adjustment.
It may be necessary to increase wheel drive belt tension under certain operating

spring force.

wheel shield. Locate bolt assembly in the desired position as follows:
