Where is the PTO clutch?
The PTO clutch is mounted under the tractor or mower beside the power drive shaft, which is also vertically aligned. It is connected to the blade shaft, and when it spins, the blade spins too. There is a belt that is attached to the drive shaft and PTO clutch pulley.
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.
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 clutch for?
Power take-off ( PTO ) clutches provide a mechanical disconnect between the power created by gas and diesel engines or electric motors to another piece of equipment. The PTO clutches enable the transmission of that energy to auxiliary equipment that does not generate its own power.
How does the PTO on a tractor work?
The tractor’s stub shaft, often called the PTO, transfers power from the tractor to the PTO -driven machine or implement. Power transfer is accomplished by connecting a drive shaft from the machinery to the tractor’s PTO stub shaft. The PTO and drive shaft rotate at 540 rpm (9 times/sec.) or 1,000 rpm (16.6 times/sec.)
What is live PTO on a tractor?
A live PTO works with the use of a two-stage clutch. Pressing the clutch half-way will disengage the transmission while pressing it fully will disengage the transmission and the PTO. This allows the operator to slow down or change gears while the PTO is still operating.
How does a PTO slip clutch work?
A PTO slip clutch is a torque limiting device that, when overcome with too much torque, limits the amount of torque being transferred from the tractor to the implement. This is accomplished by, you guessed it, slipping or spinning free which allows the two sides of the PTO shaft to spin at different speeds.
How long should a PTO clutch last?
LawnSite Member See people getting 600 – 1000 hours having to replace.
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.
