“…Measurement of implement draft and developing draft prediction equations has received most of the attention in tractor instrumentation systems (Zoerb et al, 1983;Musunda and Bigsby, 1985;Harrigan and Rotz, 1995;Grisso et al, 1996;Al-Suhaibani andAl-janobi, 1997 andKheiralla et al, 2004). Many of the results of these researches have been summarized in ASABE Standard D497.6 (ASABE Standards, 2009).…”

A mobile instrumentation system was developed and mounted on an MF 285 tractor to measure the performance parameters of the tractor and attached implements. The system measures implement draft, fuel consumption, real forward velocity, tillage depth and engine speed. Other parameters such as wheel slippage, drawbar power and traction efficiency would be calculated by ASABE standard. Overall energy efficiency for the tractor-implement system was calculated, too. Three implements included of moldboard plow, disk plow and chisel plow at four forward velocities (1.5, 2.3, 3 and 4 km/h) in 23 cm depth and 1500 rpm engine speed was examined. Analysis of variance (ANOVA) of resulted data revealed that increase of forward velocity results in increase of implement draft, wheel slippage, drawbar power and overall energy efficiency but results in decrease of traction efficiency. Furthermore, fuel consumption decreased by increase of velocity from 1.5 km/h to 3 km/h but increased by increase of velocity from 3 km/h to 4 km/h. Moreover, it was observed that draft requirement for implements in tests ranged from 8.2 kN for the disk plow to 13 kN for the chisel plow and fuel consumption ranged from 10.72 L/ha for the chisel plow to 26.5 L/ha for the moldboard plow. The ranges in mentioned parameters indicate that energy saving can be readily done by selecting energy-efficient implements and by proper matching of the tractor size and operating parameters to the implements. ª 2015 The Authors.

“…Studies on conventional and reduced tillage in scientific literature have provided a large amount of information on methods, labour and energy in different soil conditions (Al Suhaibani and Al-Janobi, 1997;Arvidsson et al, 2004;Wandkar et al, 2013), but only a few gave a comprehensive picture of the energy request and of the quality of tillage for the most common methods performing primary tillage in compact soils. McLaughlin et al (2008) studied energy inputs and draft for eight different primary tillage implements in a clay loam soil, but no data on tillage quality parameters were provided.…”

“…Conventional tillage systems may produce undesirable effects, such as worsening of soil structure due to compaction, loss of nutrients in deeper layers and of organic matter in upper depths (Lal, 2004), increasing soil erosion caused by wind or by surface runoff (De Laune and Sij, 2012), excessive energy requirements and costs (Perfect et al, 1997). These effects can be reduced, especially in compact clay soil, by replacing conventional implements with soil conservation tillage equipment, to reduce the number of passes, the working depth, the fuel consumption and the energy input (Raper and Bergtold, 2007;Fanigliulo and Pochi, 2011), by using one pass implements with wider working width and equipped with suitable geometry working tools (Godwin, 2007).The availability of data on energy requirement, fuel consumption and force of traction of tillage implements is the main factor to determine the power class of the required tractor (Moitzi et al, 2013;Pochi et al, 2013) and to estimate the effects of different implements in relation to the quality of the tillage in specific soil types, in terms of depth of tillage, soil cloddiness and crop residue or biomass cover (Raper et al, 2000;Chen et al, 2004;Sahu and Raheman, 2006).Studies on conventional and reduced tillage in scientific literature have provided a large amount of information on methods, labour and energy in different soil conditions (Al Suhaibani and Al-Janobi, 1997;Arvidsson et al, 2004;Wandkar et al, 2013), but only a few gave a comprehensive picture of the energy request and of the quality of tillage for the most common methods performing primary tillage in compact soils.

The use of agricultural machinery represents the main aspect contributing to the total energy input in the agricultural system. The study evaluated the energy requirements and the work quality of two conventional (threefurrow plough and spading machine) and of four conservation implements (rotary harrow, subsoiler, disk harrow, combined cultivator) for mediumdeep primary tillage in a silty-clay soil, widespread in Central Italy. The tests were carried out with the aim of selecting the most energy-efficient implement. Working speed, force of traction, fuel consumption and energy demands were measured, using a 205 kW instrumented tractor. Cloddiness and roughness of the tilled soil, biomass coverage index and burying degree were evaluated. The conservation tillage implements gave the best results in fuel consumption and energy requirements respect to the conventional implements, with energy savings up to 86% in the case of disk harrow. The rotary harrow showed intermediate values and the best soil refinement. Among the conservation implements, the disk harrow showed the best performance on biomass coverage index (43.8%), while the combined cultivator showed the highest value of biomass burying (87.8%) and the best performance on fuel consumption per hour (25.8 kg h -1 ). IntroductionPrimary tillage represents the major soil manipulation and the required implements can be utilised both in conventional and conservation tillage systems. Conventional tillage systems may produce undesirable effects, such as worsening of soil structure due to compaction, loss of nutrients in deeper layers and of organic matter in upper depths (Lal, 2004), increasing soil erosion caused by wind or by surface runoff (De Laune and Sij, 2012), excessive energy requirements and costs (Perfect et al., 1997). These effects can be reduced, especially in compact clay soil, by replacing conventional implements with soil conservation tillage equipment, to reduce the number of passes, the working depth, the fuel consumption and the energy input (Raper and Bergtold, 2007;Fanigliulo and Pochi, 2011), by using one pass implements with wider working width and equipped with suitable geometry working tools (Godwin, 2007).The availability of data on energy requirement, fuel consumption and force of traction of tillage implements is the main factor to determine the power class of the required tractor (Moitzi et al., 2013;Pochi et al., 2013) and to estimate the effects of different implements in relation to the quality of the tillage in specific soil types, in terms of depth of tillage, soil cloddiness and crop residue or biomass cover (Raper et al., 2000;Chen et al., 2004;Sahu and Raheman, 2006).Studies on conventional and reduced tillage in scientific literature have provided a large amount of information on methods, labour and energy in different soil conditions (Al Suhaibani and Al-Janobi, 1997;Arvidsson et al., 2004;Wandkar et al., 2013), but only a few gave a comprehensive picture of the energy request and of the quality of tillage for the mos...

“…As tractor power and speed increase, its travel reduction decreases while the drawbar pull increases (Shebi et al 1988;Bukhari et al 1988). Al-Suhaibani and Al-Janobi (1997) examined the effect of speed and depth on the draught of a chisel plow, an offset disk harrow, a moldboard plow and a disc plow on a sandy loam soil. They observed that a significant increase in draught for all the tested implement with the increase in speed.…”

The objective of this study was to investigate the effect of tractor power and forward speed on the drawbar pull, wheel slippage and fuel consumption when a 2WD tractor was linked with a mounted disc plow and working on a clay loam soil. Two levels of tractor drawbar power and three levels of forward speed were evaluated. Results showed that the increase in tractor power and speed and their interaction had a highly significant effect on these three field performance parameters. It was found that as the tractor power increased from 53.2 kW to 68.4 kW, the average pull increased by 55%, while the increase in tractor speed from 5 km/hr to 9 km/hr increased the pull by 39% and 36% for the medium and large tractors, respectively. When the power of the tractor was greater, the average wheel slippage was reduced up to 55%, but when the higher speed was used the average slippage was increased by 31% and 12% for the two tractors, respectively. The average fuel consumption rate was observed to be increased with the increase in tractor power and speed giving an average increase of 60% with the bigger tractor. However, using the higher speed gave an average increase in fuel consumption of 72% and 60% for the two tractors, respectively. The multiple correlation analysis indicated that power and speed accounted jointly for 98.1%, 97.7% and 92.6% of drawbar pull, slippage and fuel consumption rate variability, respectively. The big tractor (68.4kW) working at medium speed 7km/hr showed a tendency to give optimum values of the three field parameters operating on this type of soil.
