STEERING TOE-IN _________________________________________________________

1. Turn wheels to straight ahead position.
2. Loosen jam nuts (N) on both sides of tie rod (M).
3. Turn tie rod (S) to provide proper toe-in. Toe-in must
not exceed +1/16 in. (+0.15 cm) (P). Re tighten jam
nuts.
4. After adjusting tie rod, adjust steering cylinder by
threading the rod (T) in or out of ball joint so spindle
arm (R) clears the stop on the axle by 3/4 ± 1/16 in.
(1.9 ± 0.15 cm) (U) when cylinder is fully extended.

TRACTION CONTROL SYSTEM CALIBRATION _________________________________

The Traction Control System (TCS) will need to be
calibrated when a system component has been replaced
or the system is not working correctly. System
components include controller, lift valve, lift cylinders, or
hoses.
1. Allow hydraulic system to become properly warmed
up. An operator must be in the seat during the
calibration procedure.
!
WARNING
Never operate the engine without proper ventilation;
exhaust fumes can be fatal when inhaled.
While warming up the hydraulic system for the
calibration procedure, the cutting unit blades will be
turning. Make certain that the area under and around
the cutting units is clean and any debris that can be
thrown from the machine is cleared away. Keep
bystanders away from unit.
a. Start engine and move throttle to full position.
b. Release the parking brake.
c. Turn PTO switch ON.
d. Fully lower cutting units to the ground.
e. Engage traction control system.
f. Allow unit to run for 5 minutes with these set-
tings.
2. System must be calibrated with the engine running,
operator in seat, PTO switch in OFF position,

parking brake switch ON and traction pedal in
Neutral.
3. Fully lower cutting units. Verify all five decks are all
the way down.
4. Press and hold TCS switch for 5 seconds. Horn will
beep when controller enters calibration mode.
NOTICE
Do not release switch until horn stops for both starting
and finishing the calibration procedure.
Do not rush through steps 5 and 6. System will not be
properly calibrated if decks do not start to raise in step
5 and are not fully lowered during step 6.
5. Tap the lift lever to raise position and wait for 3 to 5
seconds. Repeat if required until cutting units just
begin to raise.
6. Tap the lift lever to lower position and wait until
decks stop moving. Repeat, tapping joystick if
required until front decks are on the ground.
7. Press and hold TCS switch until horn beeps.
System is now calibrated.
NOTICE
To cancel calibration mode, turn keyswitch to the OFF
position.
