“…However, at higher speeds, the increase in the vertical force acting on the moldboard plow showed a specific trend. Increasing the depth at the same speed led to larger increases in the vertical force, while this increase occurred with a slower slope with increasing speed at the same depth, which is consistent with the reports by Askari et al [24] and Kasisira and du Plessis [31,32]. The high vertical force in the para-plow equipped with forward-bent wings is an indication of the tendency of this implement to penetrate to the soil.…”

“…In all treatments, the draft force of the moldboard plow was higher compared to other implements. The draft force of the para-plow equipped with a backward-bent wing in all working speeds and depths was lower than para-plow equipped with backward-bent wings, which was predictable due to the shape of the wings and the higher interaction of wings with the soil in the para-plow equipped with forward-bent wings, and the results showed good consistency with the research by Askari et al [24]. The trend of the increase of draft force with the increase of working depth and forward speed occurred without sudden increase and linearly.…”

“…Field experiments were carried out on the research fields of Mohaghegh Ardabili University (longitude E 48°17′35″, latitude 38°12′40″, and altitude 1350 m above sea level) where wheat residues from previous cultivation had remained on the ground. The experiment was performed at three working depths of 10 cm, 20 cm, 30 cm; three forward speeds of 2 km/h, 5 km/h, 7 km/h; and using a moldboard plow and para-plows with three different wing levels [24] including without wing, with forward-bent wing, and with backward-bent wing (Figure 1). The soil of the experimental site was clay loam (Cambisols in World Reference Base for Soil Resources (WRB), International Union of Soil Sciences (IUSS), 2014, Vienna, Austria).…”

The objective of this study was to measure the draft, vertical, and lateral forces acting on the moldboard plow, para-plow without a wing, para-plow with forward-bent wing, and para-plow with a backward-bent wing at three working depths and three forward speeds in clay loam soil to investigate the use of a suitable para-plow instead of the moldboard plow. Also, modeling the draft, vertical, and lateral forces acting on the implements using Adaptive Neuro-Fuzzy Interface System (ANFIS) was another objective of this research. To measure the draft, vertical, and lateral forces, a three-point hitch dynamometer was used. The results showed that, with the increment of the forward speed and working depth, the draft force required by the used implements increased. This increase was also true for vertical and lateral forces acting on the implements. Modeling of the draft, vertical, and lateral forces acting on the implements was performed using the effective parameters of the implements, working depth, and forward traveling speed using the (ANFIS) fuzzy neural system model. The root mean square error (RMSE) for the draft, vertical, and lateral forces for the above models were obtained equal to 0.121, 0.014, and 0.016, respectively.

“…Bentleg penetrated to the soil easier compared to the conventional tine due to the low rake angle and. As a result, a low soil disturbance occurred, so the value of MWD was higher (Askari et al, 2019). The soil fractionation rate depends on the rake angle of the Bentleg tine (Fig.…”

One of the main aims of tillage operation is to provide a seedbed with appropriate soil fragmentation and to create relatively large aggregates of topsoil to achieve conservation tillage. Considering that subsoiling is necessary for hardpan breakup, the creation of a seedbed with the same operation can increase the operation efficiency. The present study was conducted to investigate the effect of tine type on soil aggregate. For this purpose, we tested four subsoiling tines of conventional, Bentleg, Paraplow, and winged-Paraplow in the field at soil moisture contents of 8, 12, 16, and 20% and the tractor forward speeds of 0.5, 1, 1.2, and 1.4 m/s. Soil fragmentation was evaluated in different depths of 10, 20, 30, and 40 cm. Winged-Paraplow and Paraplow, compared with two other tools, showed more soil disturbance due to having a wing and chisel at the end of the tine. The highest mean weight diameter (MWD) =19.9 mm was reached using a Bentleg at a depth of 10 cm and moisture content of 20%. In comparison, the lowest value of 3.37 mm was related to the winged-Paraplow at a depth of 40 cm and moisture content of 8%.Considering the aggregate size of 0.5-8 mm for providing a proper seedbed, the winged-Paraplow tine is a suitable tool that can provide seedbed at any depth at a water content of 0.8PL, where PL denotes plastic limit. At slow forward speeds, fine particles had enough time to sift to a deeper layer, which is beneficial for seedbed creation. Reducing the soil moisture increased soil disturbance and its fragmentation. Moreover, it was observed that MWD was higher at high moistures..

“…Currently, it is recommended that the field after pre-winter plowing should be as even as possible. The point is that the field surface should have a relatively similar humidity, which will allow the soil to heat and dry in the same way in spring [1]. The agrotechnical guidelines for deep plowing recommend that it should be carried out always to the depth of the entire thickness of the soil before the planned cultivation of root crops.…”

The development of the agricultural industry is aimed, among others, at a significant increase in the field area being processed by individual farmers. As the farmland that needs to be processed is getting bigger and the time to perform the work has not changed, it is necessary to constantly increase the efficiency of agricultural machinery. This fact requires the use of innovative solutions and materials that will meet the task given to them. One of the hardest working machines are plows. Their main parts are introduced to dynamic, complex states of stress. Among many of its components, there is the material shear stress caused by friction of the share against the soil. The material used for the production of this part (usually one of the steel grades) must, inter alia, have good abrasion resistance. This work proposes a quick and relatively cheap method of checking/comparing material/materials in terms of their resistance to abrasive wear. For this purpose, the so-called ball-cratering method was used, which consists measuring micro-wear in the sample-ball contact. By using this method, it is also possible to test modified surfaces, e.g., coated or toughened. As the name suggests, it is a very precise method, so it is necessary to correctly select the input parameters. To meet this requirement, the Taguchi process optimization method was used. By using the developed method, good accuracy and repeatability of results could be obtained, which is extremely important in research processes.
