“…Because the soil flow at the end leg of a subsoiler has compressed to less flow profile compared the flow domain, thus velocity is increasing. The same trend was report for the variation of the soil speed; the soil is disturbed in front of the active body and the distribution pattern of the flowing speed clearly indicates the region where the cracks appear [8].

Use of soil tillage tool in agricultural field wants for soil failure. Behavior of soil failure: soil deformation and soil failure depend on soil properties and action force method. The subsoiler used to change the depth of soil from the surface to the ground breaking into a small block. The objective of this research was to determine soil flow pattern around the subsoiler type curved leg used computational fluid dynamics and to study soil fracture and soil movement of subsoiler type curved leg. Simulations carried out using ANSYS Fluent 14.0 commercial CFD software. The computational fluid dynamics used predict the soil flow through subsoiler type curved leg at subsoiler operating speed constant. For a subsoiler speed of 1.02 m s-1 , with operating at 400 mm depth, rake angle of 30°. The results show, the soil failure is lateral deformation of subsoiler and soil movement on the surface of rake angle.

The article presents the results of a field survey of the work of a spading machine. The influence of the following factors on the structure of the Chernozem type soil has been investigated: operating speed, deflector cover deflection angle and rotation speed of the power takeoff shaft of the tractor on soil crushing. The relative share of aggregates smaller than 1mm, from 1 to 10mm, from 10 to 25mm, from 25 to 50mm, from 50 to 100mm and over 100mm has been determined. Regression relations have been created to determine the proportion of soil fractions of certain sizes depending on the controllable factors. The operating speed and the position of the machine cover have the greatest influence on the granulometric composition of the soil in cultivation with a spading machine. The resulting regression relations can be used to determine the operating parameters of the machine to achieve the desired granulometric composition of the soil depending on the purpose of the cultivation.

“…The basic aim in tillage operations is always to provide the seedbed required for plant growing, with the least possible number of passes and minimum energy consumption. In order to reduce the number of passes, tillage machines with active tillage tools are preferred (Cujbescu et al, 2019;Tenu et al, 2012).…”

Tillage is the most energy-intensive soil operation. In the actual energy situation is important to explore and analyze the physical laws of soil cultivation processes, that demand large energy quantities, at the border of technical- and agricultural sciences. We studied the physical phenomenon’s occurring during the work with a rotary tiller and approximated the energy requirements with a computer simulation using Matlab Simulink environment. The model used was a simplified solid model of an FPP-1,3 type rotary tiller, used previously in real experiments to determine fuel consumption at various working parameters. The results obtained with the dynamic simulation were compared with the real measurements.
