Traction Pedal; Steering Toe-In - Jacobsen HR 9016 Turbo Parts & Maintenance Manual

3 ADJUSTMENTS
3.11 PARKING BRAKE _________________________________________________________
1. Check linkage and pivots to ensure they are
operating smoothly. Inspect parking brake and
steering assist cables.
2. Park the mower on a 30% slope (16.7°) near the
bottom of the hill, with the front of the mower facing
downhill. Engage the parking brake and stop the
engine.
a. The mower should stay on the hill without
creeping.
b. If the brakes do not hold, start the engine,
disengage the brake, and drive to the bottom of
the hill.

3.12 TRACTION PEDAL_________________________________________________________

The traction pedal must be adjusted so the pump is at full
stroke when the pedal is fully depressed in the forward
position.
1. Make sure return arm (K-Figure 3H) on pump is
adjusted to neutral, Section 3.6.
2. Push traction pedal forward (I) until it touches floor
panel and hold in this position.
3. Adjust turn buckle (J) until you feel the return arm
hit the internal stop in pump. Backoff rod 2-3 turns
from this position. This ensures that the traction
pedal bottoms out before the return arm.

2. Loosen jam nuts (M) on both ends of tie rod (N).

3. With parking brake disengaged, turn adjusting knob
in a clockwise direction, applying and releasing
brake every quarter turn, until a definite "snap over
center" action is achieved.
4. Repeat the test on the hill if required.
Note: Over adjustment causes hard lever action, but
does not increase brake efficiency.
