Chelsea Crankshaft Driven PTO

crankshaft driven PTO

A Crankshaft Driven PTO is driven by the front of the engine crankshaft. They are mostly used in heavy-duty and extra-heavy-duty applications requiring auxiliary power while the vehicle is in motion. A clutch-type Crankshaft Driven P.T.O. is preferred because it can be engaged without shutting off the engine. A mechanical shift can be used as long as the engine is shut off when engaging or disengaging the PTO. Our Chelsea crankshaft drive PTOs give you the ability to have more control over your PTO and what you can do with it. If you have any questions or need assistance don’t hesitate to call us at 877-776-4600 or 407-872-1901. We offer worldwide shipping and have experts standing by ready to help.
