The Reaper-binder which is driven by the power-take-off drive of the tractor and easily attached to the tractor by its three-point hitch is a very useful and practical machine that needs very little maintenance and it reaps and binds the crops such as wheat, wheat grained barley, oat, rye and leaves them collectively on the farm at regular intervals. The cutting height which is adjusted by its hydraulic sleeves automatically preserves its level in accord with the unevenness with the help of a spring.The machine parts are protected with a safety mechanism against the possible overloads.
