“…In this study, speed ratio (u/v), depth of operation (DO), and CI were selected as independent parameters, and the specific energy (SPE) requirement as the dependent parameter. The SPE of the system was calculated from the measured draft and torque (Equation ( 6)) which is the ratio of equivalent power to the actual field productivity of the implement [24,30,37,38].…”

Specific energy prediction is critically important to enhance field performance of agricultural implements. It enables optimal utilization of tractor power, reduced inefficiencies, and identification of comprehensive inputs for designing energy-efficient implements. In this study, A 3-5-1 artificial neural network (ANN) model was developed to estimate specific energy requirement of a vertical axis rotor type intra-row weeding tool. The depth of operation in soil bed, soil cone index, and forward/implement speed ratio (u/v) were selected as the input variables. Soil bin investigations were conducted using the vertical axis rotor (RVA), interfaced with draft, torque, speed sensors, and data acquisition system to record dynamic forces employed during soil–tool interaction at ranges of different operating parameters. The depth of operation (DO) had the maximum influence on the specific energy requirement of the RVA, followed by the cone index (CI) and the u/v ratio. The developed ANN model was able to predict the specific energy requirements of RVA at high accuracies as indicated by high R2 (0.91), low RMSE (0.0197) and low MAE (0.0479). Findings highlight the potential of the ANN as an efficient technique for modeling soil–tool interactions under specific experimental conditions. Such estimations will eventually optimize and enhance the performance efficiency of agricultural implements in the field.

“…It was noted that draft and clod mean weight diameter (MWD) significantly decreased compared to separate operation. Moreover, the soil surface was more uniform than using mouldboard plough and disk harrow as a common method [19]. Javadi and Shahidzadeh developed combined equipment with chisel plough behind of mouldboard plough and indicated that the combined plough enabled to break plough pan during ploughing in one pass and would avoid un-necessary sub-soiling in deep soil layers separately [20].…”

To improve the mechanization level in India, a low-cost tractor that can be afforded by a normal farmer and also suitable for Indian land size is very much required. One way to reduce the cost of mechanization is optimum utilization of the tractor power for any agricultural operation. For these matching, implements are required for the developed tractor which can use the tractor rated power optimally. To further reduce the cost of operation, two tillage operations can be combined by combining two implements. Hence, a combined Cultivator and Disk Harrow (C-DH) was developed and tested in the Research Farm of College of Agricultural Engineering, Madakasira. The tests were carried out with two speeds and three different depths in each speed. The plots of 50×25m size were selected for the test parameters such as the speed of operation. The time required to travel 25m test length, turning time, depth of operation, the width of operation were recorded. Quality of work was judged by the Mass Median Diameter (MMD) of soil aggregates collected before and after operating C-DH implement in the plot and conducting sieve analysis. From the test results, the average field capacity of the C-DH implement was found to be 0.30 and 0.61 ha/h at 1.8 and 3.4 km/h respectively. The overall performance was expressed in term of Performance Index and was found to be 548.54 at the depth of 13 cm and a speed of 3.4 km/h.

“…Tillage tools are often designed to minimize the draft force and power requirements (Bögel et al., 2016). Various combinations of machinery or implements with rotary-powered tillage have been developed and have been found to be more energy efficient than similar single, passive tillage tools when they were tested under actual field conditions (Shinners et al., 1993). A combined tillage tool simultaneously uses two or more types of tillage implement to accomplish primary and secondary tillage in a one-pass operation for seedbed preparation (Prem et al., 2016).…”

“…Reduction in the draft force due to the soil cutting of the active tool providing some thrust force (Shinners et al., 1990). More effective operational power use due to the direct transmission of power to the tillage elements through a mechanical power train rather than through the soil-tire interface (Anpat and Raheman, 2017; Hendrick, 1980; Shinners et al., 1993). Fewer larger-sized clods in the soil, which provide medium soil uniformity, good moisture holding capacity, and eventually reduce evapotranspiration (Kailappan et al., 2001; Janeth et al., 2014).…”

Reducing energy use in soil preparation has become increasingly important since it is a major cost in planting. Experiments were conducted with a combined tillage implement consisting of a subsoiler and a rotary harrow to reduce the cost due to step reduction in soil preparation. Three tillage operations, two forward speeds, and two rotational rotor speeds were determined as input factors in this study. Soil clod size, performance parameters, and the specific energy requirements of a combined tillage implement were investigated. The field experiments were using two different soil conditions. Increasing the rotor speed from 299 to 526 rpm decreased the mean soil clod diameter at a depth of 0–200 mm from 22.98 to 19.83 mm and from 31.77 to 26.57 mm for fields 1 and 2, respectively. The specific energy requirement was affected significantly by rotor speed and tillage operation. The specific energy requirements for the combined tillage implement with an on-frame pivot joint and an on-pivotable-shank joint were less by 10.4 and 21.1% and by 18.4 and 24.7%, for fields 1 and 2, respectively, compared to the total power requirement for the separate use of a subsoiler and a rotary harrow.
