Attach the plow.
The plow hitch is located in its front part. It is used to connect the plow to the tractor. The hitch includes a cross beam attached to the plow frame, longitudinal beam - the so-called. pull bar, oblique beam - the so-called. strut stiffening the drawbeam, a hitch hook and a fuse mounted at the end of the drawbeam. The fuse is to automatically disconnect the plow from the tractor in the event of excessive resistance to operation.
The simplest fuse is a circular fuse, which is truncated when the permissible resistance is exceeded, which disconnects the plow from the tractor. operating diagram of a spring fuse. At the moment of the plow overload, the safety spring is deflected, and the hook slides out of the yoke, which allows the plow to detach from the tractor. To reposition the hook to the horizontal position, the yoke should be folded back. Plowing can then be done again, when the obstruction is removed, which caused the overload. The most favorable working conditions for the plow and the tractor are then, when the plow drawbar is positioned in the plow resistance line passing through the center of the plow working width and is hooked on the longitudinal axis of the tractor. This method of attaching the plow to the tractor is possible only for plows with a width equal to or greater than that of the tractor.
