Never ride on a tractor with anyone. Fenders, drawbars, and steps are not safe places to sit while the tractor is moving. Tractors are designed with one seat, and this is for the driver. Runovers can occur even if you are not riding on the tractor. You should never approach a piece of working equipment.
Tractors are big pieces of machinery and can be very noisy.
The driver may not see or hear you approach. If the driver does not know that you are there, he may back over you, or crush you between the equipment and tractor. The Power Take-Off shaft , commonly called a PTO, is a very dangerous area on the tractor. A PTO is located at the rear of the tractor and spins at a very rapid speed. It provides power to the attached farm equipment.
