The use of hydraulic cylinders in plows.
Unlocking from the position determined in this way is performed by the tractor driver by pulling the cable attached to the locking lever. The pawl is disengaged during normal operation of the plow and during transport, and the field wheel turns loosely on the shaft. When lifting the plow, the field wheel is heavily loaded and in difficult conditions, even slippage may occur, preventing the plow's lift.. To prevent this, this wheel is often equipped with spurs. In the latest designs of plows attached to raise and lower the frame, and also for plowing regulation, double-acting hydraulic cylinders are used. For this purpose, an external hydraulic system is used, in which modern agricultural tractors are equipped. The hydraulic lifting system allows for quick and precise plowing depth setting, enables the plow to be raised when stationary, and also makes the lifting capacity of the plow independent from the slippage of the field wheel. In older plows, the so-called frame was used to raise the frame. ladder lift. Currently, plows with this jack are no longer available.
