Ploughing quality and energy consumption depending on plough bodies type

Abstract Experimental determination of ploughing quality and energy consumption carried out on loamy soils most common for the arable lands in European part of Russia. The field tests done for three standard types of mouldboard body surfaces: cultural, semi-helicoidal (cylindroid) and helicoidal. Results shows that bodies with cylindroid mouldboard surface had better soil crumbling against cultural (digger) body surfaces. Helicoidal bodies supplied better quality of soil layer turnover than cultural and semi-helicoidal ones. Designed plough construction allowed change ploughshares installation angles relative to the furrow line from 25 to 55°. Optimal ploughshares angle to the furrow line obtained 45…50°. The traction resistance force of the plough equipped with helicoidal bodies was measured 6…8% lower than cultural bodies and 3…4% lower than cylindroid ones at tractor speed 2.5…3.0 m-s -1 .
