Neutral Adjustment; Return-To-Neutral Adjustment; Parking Brake Adjustment - Ferris IS700Z series Operator's Manual

Neutral Adjustment

The neutral system for this mower consists of two neutral linkage
rods and a pivot that connect the ground speed control lever to
the transmission. The lower rod that connects the transmission
to the pivot is factory preset and should not be changed for
neutral adjustment purposes. The adjustment is achieved by
changing the length of the upper rod (A, Figure 41) that connects
the ground speed control lever to the pivot.

Determining if Adjustment is Necessary: If the tractor
"creeps" while the ground speed control levers are locked in
the NEUTRAL position, then it is necessary to adjust the neutral
linkage rods.
Note: Perform this adjustment on a hard, level surface such as
a concrete floor.
1. Disengage the PTO, engage the parking brake and turn off
the engine.
2. There are two nuts (B) on the linkage rod (A). Loosen the
nuts from the ball joints and turn the linkage rod to adjust.
• If the machine creeps forward, turn the rod clockwise
(while standing at the rear of the machine facing
forward);
• If the machine creeps backwards, turn the rod
counter-clockwise (while standing at the rear of the
machine facing forward).
3. Lock the nuts against the ball joints when neutral is
achieved.
Note: The adjustment should not be performed while the
machine is running. It may take several attempts to achieve
neutral, depending on how much the machine creeps.

Return-to-Neutral Adjustment

Prior to performing this procedure the Neutral Adjustment
Procedure must be completed.

WARNING
To avoid serious injury, perform adjustments only with engine
stopped, key removed, and tractor parked on level ground.
1. Lock the ground speed control lever in the neutral position.
2. Loosen the set collar (A, Figure 42) on the neutral return
rod (B).

3. Position the set collar along the neutral return rod until it
contacts and very lightly compresses the neutral return
spring (C).
4. Move the ground speed control levers into the operating
position, pull rearward, and release.
5. Move the ground speed control levers out towards the
neutral position.
• if the ground speed control lever aligns with the notch
in the neutral lock plate, adjustment is complete;
• if the ground speed control lever stops it's return motion
past the notch (while standing at the rear of the
machine), re-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
machine), re-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.

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
