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.
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 settings.
2. System must be calibrated with the engine running,
operator in seat, PTO switch in OFF position, parking
brake engaged 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.
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

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.
NOTICE
Do not release switch until horn stops for both starting
and finishing the calibration procedure.

NOTICE
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.
NOTICE
To cancel calibration mode, turn keyswitch to the OFF
position.
