How do you troubleshoot a PTO clutch?
How to Test a PTO Clutch
- Lift the utility vehicle up with a floor jack.
- Place the negative voltmeter lead on a good engine source.
- Look for the in-line fuse between the electrical wiring harness from the lever switch to the PTO clutch assembly under the deck.
- Start the engine and let it warm up.
Why does the PTO not engage?
If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it. If the switch is defective, it may not supply power to the PTO clutch.
How do I know if my electric PTO clutch is bad?
Activate the PTO engagement lever, then disengage it. Turn it on and off several times. If you do not hear a disengagement noise or see the power takeoff pulley stopping or slowing down at any time, it indicates the clutch and plates have galled together from excessive heat, or the slip ring has jammed.
How long does a PTO clutch last?
LawnSite Member See people getting 600 – 1000 hours having to replace.
How many ohms should a PTO clutch have?
Anywhere between approx. 2 ~ 4 ohms is acceptable but no way does that mean the clutch is OK. Temperature and your meter will give you varying readings. I wouldn’t replace the clutch because it has 1.8 ohms of resistance.
What is a PTO switch?
The PTO is a switch or lever found on tractors and mowers and stands for Power Take Off. This can be an electric switch or mechanical engagement that takes engine power to operate the mower deck or an implement.
How does a PTO clutch work?
Driven by electricity provided by the mower’s 12-volt battery, the PTO clutch engages when its solenoid receives an electric spark. The PTO pulley is attached to the clutch and guides the belt that connects to the engine crankshaft pulley and rotates the blades of the mower that are located under the mower’s deck.
What does a bad PTO clutch look like?
“Normally” when a clutch is going bad it will start to show when you engage the PTO. A common symptom would be for the clutch to be slow to engage if it’s been running for a while and is hot. Once engaged they usually stay engaged until you shut them off.
Why did my mower blades stop working?
If your mower blades will not turn after the blade controls have been engaged, your deck belt may be broken. The deck is located directly under the operators seat. This belt spins the mowers blades and runs through a pulley system of idlers. If the belt has snapped, it will need to be replaced.
