PTO Driven trailers are specially designed for use in difficult terrain. A PTO driven trailer has a live axle which is powered by a tractor's Ground Speed PTO. Full traction for the tractor and trailer is always guaranteed when climbing hills or in wet/soggy conditions. This powered trailer eliminates tractor/trailer wheel slippage thus reducing road/path damage and improves fuel economy of the tractor.
