Neutral Adjustment & Tracking Adjustment - Ferris FW35 Series Operator's Manual

3. Apply a film of new oil to the gasket of the new replacement
filter. After the oil has drained, thread the new filter onto the
filter base until the gasket makes contact, then tighten 3/4
of a turn more.
4. Using a hex bit swivel socket or a modified allen wrench
remove the top port plug from the transmissions.
5. Remove the transmission reservoir cap and fill with oil until
oil appears at the bottom of the transmission's top port
(approximately 2 qts (1,89 L).
6. Reinstall the top port plug and tighten to 15 ft lbs (20,38
Nm).
7. Continue to add oil to the transmission oil reservoirs until
the oil level reaches the "FULL COLD" mark. Reinstall the
oil reservoir cap.
8. Repeat this process for the other side of the machine.
9. Run the unit for several minutes and check the transmission
oil level.
IMPORTANT NOTE: Use caution after changing the filter; air
in the hydraulic system may affect the responsiveness of the
ground speed control levers. Repeat step 11 until the air is out
of the system.
Neutral Adjustment & Tracking Adjustment
If the unit "creeps" while the forward speed control lever is in
the neutral position, then it may be necessary to adjust the
adjustment linkage rods.
The illustration depicts the left side of the machine.
Neutral Adjustment
1. Park the unit on a flat level surface such as a concrete floor,
away from bystanders and preferably facing a wall.
Disengage the PTO, engage the parking brake, turn the
ignition switch to OFF and remove the key.
2. Chock the front caster wheels. Raise the drive wheels off
the ground and secure the machine with jack stands.
3. Start the engine and adjust the throttle control to the SLOW
position. See Starting the Engine section for proper starting
instructions.
4. Loosen the jam nuts (A, Figure 30) that are tightened
against the ball joints (B).

5. Disengage the parking brake.
6. Slowly turn the adjustment linkage rod (C) clockwise until
the drive tire begins to rotate backwards.
7. Slowly turn the adjustment linkage rod counter-clockwise
until the drive tire begins to rotate forward.
8. Set the adjustment halfway in between where the forward
and backwards rotations begin.
9. Re-tighten the jam nuts.
10. Perform this adjustment for the other side of the machine.
11. Adjust the throttle control to FULL (highest setting). Cycle
the forward speed control lever and the neutral return pedals
several times to insure an accurate adjustment has been
made.
• If the unit still creeps, perform the adjustment procedure
again.
• If the unit does not creep, no further neutral adjustments
are necessary.
Tracking Adjustment
Before making a tracking adjustment, be sure to check the
following:
• Drive tires are properly inflated.
• Caster tires are greased and turn freely.
• All controls are free from damage and operate freely.
• Machine is at full operating temperature.
• Make sure the machine is in neutral when the foot pedal is
depressed. If not, adjust neutral as described above.
