What does electric PTO mean?

What is electric PTO on John Deere?

How does a tractor electric PTO 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.
How does a manual PTO clutch work?
Engaging the Clutch To get the blade to spin, the PTO clutch must be engaged. When the operator pulls the lever and engages the clutch, the pulley wheel springs outward and tightens the blade against the drive shaft pulley. Because the drive shaft pulley is turning, it spins the PTO pulley and the lawnmower blade.
How does a PTO engage?
For power shift operation, when a power shift PTO is engaged, a solenoid is energized. Air or hydraulic fluid then compresses a clutch pack in the PTO. Air or hydraulic fluid deadheads against the valve. From there, air is released to atmosphere through a valve, and hydraulic fluid exhausts into the PTO.
What does a PTO cable do?
A power take-off or power takeoff (PTO) is any of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
