A plow is an agricultural device designed to work the soil. During plowing, the working bodies of the plow crumble layers of soil, wrap them up and dump them to the bottom of the formed furrow. At the same time, all residues of stubble and weeds are embedded deep into the ground. Plowing with a single-body articulated plow SHPL-1-20 or SHPL-1-25 is carried out to a depth of 200 mm. The plowing depth and plow tilt angle are adjusted using adjusting bolts and a support wheel. This model has two modifications, differing in grip width - 0.20 m and 0.25 m, and the ability to change the angle of deflection of the plow relative to the direction of movement of the walk-behind tractor.
