How does a lawn mower clutch work?
An electric lawnmower clutch gets energy from the mower’s engine and transfers it to the mower blade. An electric clutch also performs the function of a brake to stop the blades when the PTO gets turned off. When the power to the electric clutch turns off, the magnetic energy releases control of the armature.
How do you use a clutch on a riding lawn mower?
Press the brake and clutch pedal, and start the engine by turning the key. On most models, the brake and clutch pedal is the same pedal; in essence it’s a dual purpose pedal. Shift the lawn mower into gear, and release the brake and clutch pedal.
How do I know if my lawn mower clutch is bad?
Simple test would be to remove the mower deck belt from the PTO pulley and try to engage the PTO. If it doesn’t stall, the clutch is not your problem. If it does stall I would guess you’ve had a bearing fail in the clutch. The other thing to check is the seat switch if it’s still enabled.
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.

Why does my riding lawn mower shut off when I engage the blades?
The seat safety switch on your lawn tractor is designed to shut the lawn mower off in case of a roll over. This will help prevent injury to the tractor’s operator. If the engine dies when the blades engage, it could be the result of a damaged safety switch.
How many amps does a PTO clutch draw?
Engage the PTO switch. The clutch should have an amp draw of approximately 4.0 amps. If the meter reads significantly above or below 4.0 amps, there may be a shorted coil, faulty switch or battery causing the problem. The clutch assembly should be kept free from debris buildup.
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.
What does a PTO clutch do?
