As we well know, as operators and distributors of these hard-working parts, power take offs serve quite a few uses! They began around World War I as additions to tractors and have since been adapted to fit many different purposes. Dump trucks use them to lift their dump boxes and release their loads. Fire trucks use them to pump water through their hoses. They can even be installed on trucks to operate wenches and small cranes. These add-ons provide more than just extra machinery, they provide the user with a tool that can take care of almost anything they need.
