The actual energy situation and the significant energy demand of agricultural production require the exploration and analysis of the general laws of the main processes in the field of energy, which is part of the borderline between the technical sciences and the agricultural sciences. Tillage machines change the physical properties of the soil, but at the same time the mechanical properties of the soil react to the implement. One of the basic works of seedbed preparation is harrowing. In this work we study the kinematics and dynamics of the active rotary harrow implements, taking into account the cutting resistance of the soil. The results obtained with the developed modeling methods, give reliable approximations to the experienced tilling processes.

“…Vidas [ 25 ] analyzed the efficiency of disc harrow adjustment for stubble tillage quality and fuel consumption, considering exchangeable parameters such as travel speed, disc angle, and tillage depth. In another study, Balsari [ 26 ] conducted a performance evaluation of a tractor-power harrow system under different working conditions focused on PTO torque and draft force.…”

The purpose of this study was to analyze the tillage depth effect on the tractor-moldboard plow systems in various soil environments and tillage depths using a field load measurement system. A field load measurement system can measure the engine load, draft force, travel speed, wheel axle load, and tillage depth in real-time. In addition, measurement tests of soil properties in the soil layer were preceded to analyze the effect of field environments. The presented results show that moldboard plow at the same tillage depth had a wide range of influences on the tractor’s working load and performance under various environments. As the draft force due to soil–tool interaction occurred in the range of 5.6–17.7 kN depending on the field environment, the overall mean engine torque and rear axle torque were up to 2.14 times and 1.67 times higher in hard and clayey soil, respectively, than in soft soil environments. In addition, the results showed tractive efficiency of 0.56–0.73 and were analyzed to have a lugging ability of 67.8% with a 44% maximum torque rise. The engine power requirement in hardpan was similar within 3.6–9.6%, but the power demand of the rear axle differed by up to 18.4%.

“…The consistent use of heavy machinery in agricultural fields in past decades caused an increased risk of soil compaction [1][2][3][4]. According to various authors, this phenomenon is accentuated by the intensity of transits [5][6][7], the increase in the axle load of agricultural machinery [8,9], and the rise in power and traction capacity of tractors [10][11][12][13]. The row crop systems, in which agricultural machinery frequently transits between rows during the entire growth cycle, also lead to a high risk of soil compaction [14][15][16].…”

Effects of Tractor and Soil Parameters on the Depth of the Permanent Traffic Lanes in Controlled Traffic Farming Systems

et al. 2022

One of the basic requirements for controlled traffic farming (CTF) is the precise motion of all agricultural equipment on permanent traffic lanes (PTL). Tractors of machine-tractor units are then equipped with a GNSS (global navigation satellite) RTK (real-time kinematic) system, even though in many parts of the world, and Europe as well, satellite navigation is not yet used. In this case, for implementation of the CTF system, it needs to lay such PTL tracks that would be sufficiently visible, especially when using the CTF system in multi-year agricultural crop cultivation. The PTL track depth is influenced by both tractor and soil parameters and, in this paper, this influence is studied considering the dimensionless π-terms of the similarity theory. To obtain a greater depth of PTL tracks (h), the soil cone index must be low. The low density of the soil is important, even if its effect on the parameter h is less than that of the soil cone index. A greater depth of PTL tracks is also obtained by increasing the inflation pressure in the tractor tires. Ballasted wheels are the least effective for increasing the value of the parameter h.
