Travel Speed: The forward and reverse stops re-
strain the hydrostatic unit actuating lever from be-
ing moved excessively and prevent internal compo-
nents from being damaged. The setting dimensions
shown should be used. These dimensions may be
increased if the maximum speed of the machine is
to be reduced, but the dimensions should never be
less than those indicated.
To set the forward / reverse stops correctly for min-
imum travel speeds, loosen the adjuster locknuts
and screw the adjuster screws away from the actu-
ating lever. Operate the actuating lever by hand to
its extreme / full travel position for forward travel
and move the adjuster screw to stop the actuating
lever 1.6mm before the extreme / full travel posi-
tion is reached. Repeat this procedure for reverse
travel except move the adjuster screw to stop the
actuating lever 5mm before the extreme / full travel
position is reached. Tighten the locknuts.
IMPORTANT: PREVENT DAMAGE - The
hydrostatic unit may sustain permanent damage
if the forward and reverse stops allow greater
travel than the limits indicated.
Neutral detent mechanism: Should the mower
creep forwards or backwards when the travel speed
control levers are in the neutral position it will be
necessary to adjust the neutral detent setting.
Slacken hex. nuts (1) and adjust the bracket on the
slots until the actuating lever (2) of the hydrostatic
unit is parallel with the side of the engine deck
(Neutral position).
Retighten the hex nuts securely.
Recheck the mower operation and make further
adjustments is necessary.
