One of the fallows soils problems in dry conditions is the lack of tech-nical implements that ensure moisture availability in the soil when sowing winter crops. The peculiarity of a new harrow, which has been developed by the authors, is the use of flat-cut working tools, which allows loosening the upper (5–6 cm) layer of soil without significantly removing its wet part to the field’s daytime surface. Experimental research has been carried to evaluate the operative performance of the following implement-tractor unit: a universal tractor with traction force 14 kN and the new harrowing implement. This machine-tractor unit has been compared with a conventional one for similar purposes. It included a general-purpose wheeled tractor with traction force 30 kN and a mounted behind cultivator of KPS-8 type. The exper-imental studies have established that using the new machine-tractor unit for fallow tillage in the lack of soil moisture conditions productivity is increased by at least 8%. The probability that the new harrow unit maintains the tolerance of fluctuations in the cultivation depth of the fallow field at the level of ±1 cm is 78%.

Abstract
One of the fallows soils problems in dry conditions is the lack of tech-nical implements that ensure moisture availability in the soil when sowing winter crops. The peculiarity of a new harrow, which has been developed by the authors, is the use of flat-cut working tools, which allows loosening the upper (5–6 cm) layer of soil without significantly removing its wet part to the field’s daytime surface. Experimental research has been carried to evaluate the operative performance of the following implement-tractor unit: a universal tractor with traction force 14 kN and the new harrowing implement. This machine-tractor unit has been compared with a conventional one for similar purposes. It included a general-purpose wheeled tractor with traction force 30 kN and a mounted behind cultivator of KPS-8 type. The exper-imental studies have established that using the new machine-tractor unit for fallow tillage in the lack of soil moisture conditions productivity is increased by at least 8%. The probability that the new harrow unit maintains the tolerance of fluctuations in the cultivation depth of the fallow field at the level of ±1 cm is 78%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
