Front-mounted furrow-opening machine

The invention is a novel preposed ditcher, including a frame arm and cutter disc mounted on the frame on the front frame of a hand tractor, pulley, and gear box, where the center of the cutter is lower than the front frame of the hand tractor. The frame arm is inclined downward or bent in the middle, thus shortening the distance between the ditcher and the hand tractor and reducing the front gravity moment; also reducing the height of the cutter disc, thus reducing the dip angle of the hand tractor while the ditcher is working. It has a novel, reasonable, simple structure, easy to produce and manufacture, especially reducing labor strength, increasing the linearity and operating efficiency, beneficial to prolonging the service life of a diesel engine and having an extremely great value in spreading and practicing and a wide marketing prospect.
