An electric lawnmower clutch, commonly called a power takeoff clutch (PTO), is the part of a lawnmower or riding tractor responsible for engaging the blade. An electric lawnmower clutch gets energy from the mower’s engine and transfers it to the mower blade.

How does the PTO clutch work?

PTO clutches work in conjunction with the PTO drive shaft and must be compatible with the transmission of the lawnmower. An electric lawnmower clutch gets energy from the mower’s engine and transfers it to the mower blade. This type of clutch prevents the mower from moving after the driver disengages the mower clutch.

What is a PTO pulley?

The power take off (PTO) clutch in your lawnmower is the drive pulley that transfers the power of the engine to the blade. The PTO clutch has a pulley that is usually machine cut and a housing brace. The pulley sits on the brace and is allowed to spin around the brace by a vertical axle in the center of the pulley.

Likewise, what is a mower PTO?

Mower and Tractor PTO Explained. 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. The PTO can run mowers by either a belt or a shaft.

Likewise, how do I test an electric PTO clutch? How to Test a PTO Clutch

  1. Lift the utility vehicle up with a floor jack.
  2. Place the negative voltmeter lead on a good engine source.
  3. Look for the in-line fuse between the electrical wiring harness from the lever switch to the PTO clutch assembly under the deck.
  4. 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.

How do you check a clutch switch?

Use a multimeter to diagnose the clutch switch and circuit. Remove the switch’s plug and test it for battery voltage with the meter’s voltmeter. Set the meter to measure ohms and check the switch for continuity. On a good switch, the meter should display infinity with the switch open and the pedal out, not depressed.

How does a PTO tractor work?

It features a splined output shaft to which can be attached drive shafts to power implements. A “live” PTO transfers the power directly from the engine to the implement regardless of whether a tractor is moving or at rest. The hitch has a fixed pivot connection at the upper rear of a tractor.

How does an independent PTO work?

An independent PTO means that the PTO shaft is controlled with a separate clutch. As with a live PTO, this allows for full control over the tractor while separately controlling the PTO. A hydraulic-independent PTO uses a single selector.

What is a slip clutch PTO?

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.

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 is a PTO switch on John Deere?

Most John Deere lawn mowers are equipped with an electric PTO (Power Take Off). The PTO is the mechanism that turns on the blades located under the mower deck. The PTO works off of a 12-volt system. The electric clutch is operated by a switch located on the dashboard of the lawn mower.

How does a PTO engage?

The PTO is engaged/disengaged using the main transmission clutch and a remote control mechanism which operates on the PTO itself. Typically an air valve is used to engage the PTO, but a mechanical linkage, electric or hydraulic mechanism are also options.

How does a PTO work on a truck?

The way the PTO works is that it turns rotating power into hydraulic power. The gears from the PTO box connect into the engine’s flywheel or crankshaft. The turning of the wheel or crankshaft causes a charge to build up in a hydraulic pump. The power in the pump can then be used for various purposes as it builds up.

Where is the clutch on a riding lawn mower?

Usually, this clutch is attached to the underside of the engine and is shaped as a small bell housing. From this position, it controls the mower blades. You will also be able to identify the clutch if you follow the mower blades.
