3.10 PARKING BRAKE__________________________________________________________
1.
Check linkage cables and pivots to ensure they are
operating smoothly.
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.
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.
3.11 REAR LIFT ARM ___________________________________________________________
1.
Rear lift arm position is properly adjusted when the
rear mower bumpers are putting slight pressure
against the underside of the foot rests.
2.
Disconnect lift chain (T) from crank and adjust ball
joint (U) as required.

3.12 DOWN PRESSURE _________________________________________________________
1.
Place mowers in the Fixed Mode (Section 3.18) and
lower the mowers onto a scale, capable of weighing
250 lb. (113 kg). The rear roller of the mower must
rest on the scale.
2.
To adjust pressure on rear mower loosen nuts (V)
and adjust to obtain the desired pressure.
3.
To adjust pressure on front mowers, loosen nut (W)
and adjust bolt (X). Minimum thread engagement
should be 1/2 in. (13 mm).
4.
To maintain a consistent height of cut, the down
pressure should be adjusted evenly on all three
mowers.
5.
Jacobsen, recommends the mower weight for
Floating Mode at 60 lb. (27 kg), and for Fixed Mode
at 90 lb. (41 kg).
