Adjust Traction Control Assembly
Proper control of the traction circuit is accomplished by
the traction pedal, cables and piston (traction) pump
neutral assembly. Adjustments to these components
may be required for correct operation. Use the following
information and the illustrations in the right column when
adjusting the traction control on your Greensmaster.
With the functional lever placed in the transport position,
the traction pedal should bottom against pedal stop on
platform in the full forward direction when piston pump
is at full stroke. If pump reaches full stroke before pedal
contacts stop, traction cable can experience premature
wear.
When functional lever is placed in the neutral position
with the traction pedal locked in place, the pedal should
be at a right angle (90
o
) to platform (Fig. 34). If neces-
sary, adjust location of ball joint on neutral lock cable to
allow correct angle of pedal.
In the neutral position, there should be no tension on the
traction cable. If cable is adjusted too tight, machine
could creep when in the neutral position. Adjust jam nuts
on traction cable to reduce tension on cable.
An eccentric on the piston pump neutral assembly can
be adjusted to eliminate machine creep when in the neu-
tral position (Fig. 35). Adjustments to traction pedal,
traction cable and neutral lock cable should be checked
before adjusting the eccentric. Eccentric adjustment
should be done with engine running and the traction
pedal locked in the neutral position.
