Blades would not turn after I got stuck in mud. Electric clutch.
- Turn the engine off and remove the key.
- Check for physical damage; anything look bent?
- Is the deck belt intact?
- Spin the pulley on the bottom of the clutch. Does it spin freely?
- There could be mud or grit stuck in the clutch.
- There is a drive key between the clutch and the shaft. Has this key been sheared?
- When you pull the PTO switch does the clutch make a "click"? It's possible the clutch was burnt out during the mud incidence.
PTO Clutch will not engage or stay engaged.
There is a very fine discussion on evaluating electric clutches at this site:
My JD tech manual, which covers the entire LA 100 series, agrees with the electrical specifications. It states that the Electric PTO Clutch should show the following:
- Resistance 3.7 ohms
- Current Draw 3.25 amps.
- It does not give the air gap.
It does include a note to check the PTO Clutch Key for damage or if missing. So there is a drive key between the PTO Clutch and the shaft. Additionally, it recommends checking the tightness of the cap screw. That's the screw or bolt that holds the clutch on the shaft.
