The present invention relates to systems for changing the disc direction on a tractor plow by hydraulic control using a hydraulic cylinder, electric control using an electric cylinder, electric control using an electric motor, or pneumatic control using a pneumatic cylinder, or on a tractor plow having a hydraulic cylinder, tractor plow having an electric cylinder, tractor plow having an electric motor, or tractor plow having a pneumatic cylinder for changing the tractor plow disc direction. The invention also relates to the electricity distribution systems controlling the electrical systems for changing the plow disc direction. Said systems and said plows using hydraulic, electric, or pneumatic control make the work of the driver and farmer easier, help save time, help develop the agricultural sector and increase the yield thereof, and also help save energy. The systems and plows also help reduce pollution and protect the environment by reducing fuel consumption while carrying out the same amount of work. They also contribute to work safety by preventing the risk of an accident wherein the tractor hits someone or something, or where the tractor falls over somewhere when the driver or farmer, through forgetfulness or negligence, turn around using the old lever system to change the tractor plow disc direction before stopping the tractor from moving. Additionally, the systems and plows protect the health of the driver and farmer against serious problems involving the back muscles, vertebral column, and the discs and nerves in the back, as well as preventing serious spinal cord problems for the driver and farmer due to great, tiring, and repetitive physical muscular effort while in the uncomfortable turning position for operating the lever changing tractor plow disc direction using the old lever system. |
