On turning the plough frame from one working position into the other, the cylinder executes a feed and return stroke. There is a central plunger to charge over the hydraulic fluid between cylinder chambers and there is a valve between pump and plunger. The plunger is fitted in a bush which assumes the guiding of the piston rod and is arranged at one end of the cylinder.
