1. 1

   Inspect the clutch pedal sensor (potentiometer) on the clutch pedal linkage for physical damage to the sensor fork or housing.

2. 2

   Check the wiring harness and electrical connector going to the sensor for corrosion, frayed wires, or loose pins.

3. 3

   Perform a voltage sweep test by back-probing the sensor with a multimeter. Slowly depress and release the clutch pedal to ensure voltage changes smoothly without dropouts or spikes.

4. 4

   Attempt to run the clutch pedal calibration procedure via the tractor's dash diagnostic menu to rule out a missing calibration or jumpy clutch.

1. 1

   Preparation

   Park the tractor on a flat surface, engage the parking brake, and turn off the engine. Disconnect the battery to prevent electrical shorts.

2. 2

   Removal

   Locate the clutch pedal potentiometer on the clutch pedal assembly. Disconnect the electrical connector.

3. 3

   Dismount

   Remove the mounting hardware (usually small screws or bolts) holding the sensor in place and remove the faulty sensor.

4. 4

   Installation

   Install the new clutch pedal sensor, ensuring the fork/linkage aligns correctly with the pedal mechanism. Secure it with the mounting hardware.

5. 5

   Reconnect

   Plug the electrical connector back into the sensor and reconnect the battery.

6. 6

   Calibration

   Turn the key on and enter the service/diagnostic menu on the dash display (usually by holding the 'A' or 'OK' button). Navigate to the 'Calibration' menu and select 'Clutch Pedal Calibration'. Follow the on-screen prompts, which will require you to fully depress and fully release the clutch pedal. The screen will confirm a successful calibration. Turn the key off to save the settings.
