“…Field efficiency is affected by the increase in the depth of plowing, as the efficiency decreases with increasing depth (Al-Shujairi, 2008). Some soil characteristics are affected by the increase in the speed of the machine unit and the depth of plowing, such as an increase in the resistance of the soil to penetration and an increase in the bulk density of the soil, and it may lead to a decrease in moisture content at some times (Al-Azzawi, 2022;Abo-Habaga et al, 2018). Increasing the distance between the subsurface irrigation pipes also leads to a decrease in the bulk density, as the distance of 20 cm outperformed by achieving the lowest bulk density of 1.20 µg.m -3 .…”

A field experiment was conducted to evaluate the performance of locally developed combine equipment used for several agricultural operations at once in a silt clay loam soil texture. Three factors were used. The first is the forward speed of the machinery unit, with three speeds: of 2.98, 4.37, and 6.18 km h-1, the second is plowing depths, with three plowing depths and subsurface irrigation pipes of 10/20, 15/25, 20/30 cm, the third is the distances between the subsurface irrigation pipes, with three distances of 50, 60 and 70 cm. The field efficiency of the combine equipment, soil moisture content, soil penetration resistance and soil bulk density were studied. Faltra tractor was used as a power source with a power of 88 kW (120 hp), with the combine equipment. The results showed that the speed of 6.18 km h-1 was significantly higher in obtaining the highest field efficiency. While the speed of 2.98 km.h-1 was outperformed in obtaining the highest value for soil moisture content, the lowest soil penetration resistance and the lowest soil bulk density compared to the other speeds. The depth of plowing and subsurface irrigation pipes 10/20 cm outperformed in obtaining the highest field efficiency, the highest moisture content, the least soil resistance to penetration, and the lowest soil bulk density compared to other depths. The distance of 70 cm was significantly outperformed in obtaining the highest field efficiency, the highest value of moisture content, the least soil resistance to penetration, and the lowest bulk density compared to other distances. The treatment of speed 2.98 km.h-1, depth 10/20 cm, and distance 70 cm outperformed in obtaining the highest moisture content of 19.40%, the lowest soil penetration resistance of 2.42 kg.cm-2, and the lowest soil bulk density of 0.93 μg.m-3 compared to other treatments.

The article consideres the issue of dynamic and energy analysis of the rotary tiller with planetary transmission gear and vertical rotation axis designed for orchards and vineyards. In the result of investigations, analytical expressions have been derived, which enable to determine the resistance force factors of the cultivated medium affecting the rotary tiller and to set up their changing patterns during a single rotation of the rotor in conditions of forward movement of the aggregate/working unit. It has been confirmed that in case of binary symmetric blades located at 120 degree, the resistance forces transmitted from the tiller satellites to the rotor shaft mutually balance each other, as a result of which the traction resistance force of the unit receives the possible minimum value. As regard to the resistance moments transmitted from the tiller satellites to the rotor shaft and to their main moments, it should be noted that they change significantly during a single rotation of the rotor. Particularly, the extreme values of the main moment for each tiller satellite are obtained at the finite points of the rotor’s diameter perpendicular to the forward movement of the tillage machine. Based on the driving and resistance force factors of the machine, as well as the differential equation of the motion, the term has been identified by means of the energy research of the rotary tiller, in case of which the angular acceleration of the rotor’s shaft will be equal to zero and the machine will operate without oscillations and vibrations.
