Preferably, a plurality of harrow knives are arranged on the two disk harrow.
By adopting the technical scheme, the harrow blades cut and loosen the soil, and the disc harrow rotates on the soil when ploughing, so that the harrow blades plough and loosen the soil on the soil.
Preferably, the two ends of the wheel shaft are provided with threads, and the disc harrow is fixed on the wheel shaft through nuts.
By adopting the technical scheme, the disc harrow is fixed on the wheel shaft by the screw threads and the nuts.
Preferably, one end of the traction rod, which is far away from the frame, is provided with a joint.
Adopt above-mentioned technical scheme, install whole device on the tractor through connecting.
