15.3. The lap bar pivot brackets are adjustable to suit
individual operators. See Figure 15.3.
• Carriage bolts in two square holes and two slots
provide adjustment for height and rake using a
single 1/2” wrench.
• A mechanical interlock with the parking brake
locks the steering pivot plates when the brake is
applied.
• High speed tracking adjustment is done by
adjusting rollers up or down on the steering pivot
plate to limit travel.
• The slotted connection between the steering
pivot plate and the hydrostatic pump control
allows “interlock neutral” to be aligned with true
neutral for the pump.

16. CHECKING NEUTRAL ADJUSTMENT
CAUTION: Releasing the parking brake with the
engine at top no-load speed and loose or mis-
adjusted control linkages can result in unpredict-
able or uncontrolled movement of the mower.
• If the drive system makes a pronounced whining
sound, indicating that it may be severely out of
adjustment, do not release the parking brake.
• Perform the tests in a safe area that is free of
hazards, obstacles, other personnel, or pets.
• In cases where the misadjustment is pro-
nounced, the tests may be performed at reduced
throttle settings, to help identify the nature and
location of the misadjustment.
16.1. With the engine warm and running at full throttle,
the hydro relief valves closed, and the parking
brake set: there should not be any abnormal
whining noise from the drive system.
16.2. With the engine warm and running at full throttle,
the hydro relief valves closed, and the parking
brake released: there should not be any ten-
dency for either rear wheel to creep.
16.3. If either of these issues exist, neutral adjustment
is necessary.
16.4. The creeping action will provide clues about the
adjustment that is required:
• If both wheels tend to creep, both neutral set-
tings may need to be adjusted.
• If only one wheel tends to creep, only that side
may need adjustment.
• The direction of the creepage will dictate the
direction of adjustment that is required.
16.5. Before adjusting the linkage, inspect it for any
bent, broken, stripped, worn, or loose compo-
nents. This is particularly true if a mower that
was previously operating well has suddenly
gone out of adjustment.
