19.3. Make an initial adjustment of the travel stops on
each steering pivot plate:
• Push the lap bar forward gently to the limit of its
travel as set by the hydro control linkage.
• Push the forward travel stop down against the
top of the control housing, and tighten the nut
that secures that stop.
• Mark the position of the stops with a paint
marker or magic marker; any further adjustment
will be in the downward direction from these
marks.
• It is important that the travel stops on the steer-
ing pivot plate limit the movement of the steering
linkage, protecting the down-stream linkage from
excessive control in-put loads.
• Repeat this process in the rearward direction to
set the initial rear travel stop.
19.4. Make the following preliminary checks of factors
that may effect tracking:
• Rear tire pressure between 10-12 PSI (.690-
.828 bar.), and circumference equal to within 1/
4” (6.35mm) to keep the drive wheels equal in
size and firmness.
• Front tire pressure between 20-25 PSI (1.38-
1.725 bar) to prevent drag that may pull the
mower off-track.
• Relief valves closed to prevent loss of hydraulic
pressure to either drive wheel.
• No hydraulic fluid leaks to prevent loss of
hydraulic pressure to either drive wheel.
• No brake drag to pull the mower off-track. Refer
to the BRAKE ADJUSTMENT section of this
manual for details.
• Hydraulic fluid reservoir full and up to operating
temperature.
• Pivot handles (lap bars) should be evenly
adjusted on their steering pivot plates to prevent
distorted perception of tracking issues.
• Steering linkages are functioning correctly, as
described in the LINKAGE NEUTRAL ADJUST-
MENT and HYDRO NEUTRAL ADJUSTMENT
sections of this manual.
19.5. Test the operation of the mower in a safe area
that is clear of hazards, obstacles, and other
personnel:
• With both lap bars pushed fully forward, the
mower should travel in a straight line forward.
• With both lap bars pulled fully rearward, the
mower should travel in reverse in a straight line.
19.6. If adjustment is required, loosen the stop on the
steering pivot plate controlling the faster wheel
(opposite side from the direction of the veer).
Move the stop downward to equalize the speed
of the two drive wheels at full lap bar travel.
19.7. This procedure is similar for both forward and
reverse tracking.
NOTE: Variations in turf will effect tracking when
the mower is in use. These factors include trac-
tion, soil firmness, grass depth, and grades. It is
up to the operator to compensate for these vari-
ations using the mower’s controls.
19.8. If the mower does not respond to tracking
adjustments, test the pumps and motors as
described in the DRIVE SYSTEM section of this
manual.
