E.
Lift the joystick control handle out of the
neutral position and hold it firmly in the
full forward position. Now, by hand,
rotate the coupling nut shortening the
linkage until resistance is felt from the
transmission control bottoming out in the
transmission. Rotate the coupling nut
back and forth a couple times to
confirm, and mark this position.
F.
Now rotate the coupling nut exactly
one
full turn longer
and retighten the jam
nuts.
When retightening make sure that
the ball joints on both top and bottom
are well centered so that they do not
bind up when moving the joystick handle
to the extremes of its travel.
NOTE: This full turn longer is
required
to
prevent internal damage to the
transmission.
G.
Now set the LH transmission speed.
Reconnect the linkage to the
left
side
transmission. (see left side transmission
illustration on previous page).
H.
Loosen the jam nuts on both ends of the
left
side transmission linkage. One of
these is a left-hand thread. Now rotate
the linkage rod a couple turns to
lengthen it.
I.
Hold the joystick control handle firmly in
the full forward position. Rotate the left
side transmission linkage rod to shorten
the linkage until resistance is felt from
the transmission control bottoming out in
the transmission. Rotate the rod back
and forth a couple times to be sure, and
mark this position.
J.
Now rotate the linkage rod exactly
one
full turn longer
and retighten the jam
nuts.
Make sure that the ball joints on
both top and bottom are centered.
NOTE: This full turn longer is
required
to
prevent internal damage to the
transmission.
K.
Test drive the mower to check for
tracking at full speed. If needed, slow
the fast side by lengthening the control
rod connected to the faster
transmission. Use small adjustments of
about ¼ turn. Replace the fender skirts
when done.
2. SETTING
NEUTRAL:
If, with the joystick handle in the DOWN
or start position and the engine running
the mower moves or travels, it is
necessary to adjust neutral. Raise the
drive wheels off the ground, secure the
mower on blocks or jack stands and
proceed as follows:
A.
Remove the fender skirt on the joystick
side. Loosen the two nuts on the
bottom of the joystick neutral plate just
enough so that the plate can move
freely.
