The present invention relates to systems for changing the direction of the disks on a tractor (10) plow by hydraulic control using a hydraulic cylinder (1), electric control using an electric cylinder (13), electric control using an electric motor (33), or pneumatic control using a pneumatic cylinder (53), a tractor plow (9) having a hydraulic cylinder, a tractor plow (21) having an electric cylinder, a tractor plow (41) having an electric motor, and a tractor plow (61) having a pneumatic cylinder for changing the direction of the disks on the tractor plow. The invention also relates to electricity distribution systems controlling the electrical systems for changing the direction of the plow disks. Said systems and said plows using hydraulic, electric, and 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 caused by the tractor hitting someone or something, or the tractor falling over somewhere when the driver or farmer, through forgetfulness or negligence, turns around using the old lever system to change the direction of the disks on the tractor plow before stopping the tractor. Additionally, the systems and plows protect the health of the driver and farmer against serious problems involving the back muscles, vertebral column, and the disks 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 the direction of the disks on the tractor plow using the old lever system. |
