PTO Drive Shaft
A PTO drive shaft is a mechanical component used in agricultural machinery to transfer power from a tractor’s engine to attached implements, enabling them to operate efficiently. This system allows various equipment, such as mowers, tillers, balers, and sprayers, to function effectively by utilizing the tractor’s engine power.
