Neutral Lockout Adjustment; Parking Brake Adjustment; Deck Lift Rod Timing Adjustment - Ferris ISX800 Series Operator's Manual

• if the ground speed control lever stops it's return
motion past the notch (while standing at the rear of
the unit), position the set collar so the neutral return
spring is less compressed.
• if the ground speed control lever stops it's return
motion before the notch (while standing at the rear
of the unit), position the set collar so that the neutral
return spring is more compressed.
6. Repeat the process as necessary until the ground speed
control lever aligns with the notch in the neutral lock plate.
Note: It is important to note that after every adjustment of
the neutral return rod, the lever must be pulled rearward and
released to properly check the return-to-neutral position.

Neutral Lockout Adjustment

Prior to adjusting the neutral lockout, the neutral and return-
to-neutral must be properly adjusted.
1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
the ignition switch to OFF, and remove the ignition key.
2. Chock the wheels of the unit to prevent movement.
3. Raise the seat to gain access to the neutral lockout
components.
4. Loosen the jam nuts (A, Figure 49) on the neutral lockout
bolts (B).

5. Engage the parking brake. The neutral lockout bolts will
enter the notches of the neutral lockout plates (C).
6. Position the neutral lockout bolts to the center of the
notches of the neutral lockout plates.
7. Re-tighten the jam nuts.

Parking Brake Adjustment

The parking brake mechanism consists of a two parking
brake cables, with a spring on both ends, that routes from the
transmission to the parking brake lever shaft. The position of
the parking brake cables and the compressed length of the
lower springs located by the transmissions are factory preset
and should not be changed for parking brake adjustment
procedures. The adjustment is achieved by changing the
compressed spring length of the upper parking brake springs.
1. Disengage the PTO, engage the parking brake, stop the
engine, and chock the tires.
2. Raise the seat plate.
3. Locate the parking brake springs (A, Figure 50)

4. With the parking brake engaged measure the
compressed spring length. The spring should
measure 2-1/4" (5,7 cm) when compressed.
5. If the spring length is not 2-1/4" (5,7 cm), release
the parking brake, and turn the adjustment nut (B) to
compress or release the spring.
CAUTION
Do not adjust the spring to be shorter than 2" (5,1 cm) when
compressed. This may damage the brake mechanism.
6. Engage the parking brake and re-measure the spring.
If this does not correct the braking problem, see your
authorized Ferris servicing dealer.

Deck Lift Rod Timing Adjustment

Checking the Deck Lift Rod Timing
1. Park the unit on a flat, level surface. Disengage the PTO,
stop the engine, and engage the parking brake. Verify the
tires are inflated to the correct pressure.
