“…Furthermore, the ASAE Standard Equation was formulated based on laboratory operation of tractors taken from the Nebraska Tractor Test under varying power and fuel consumption settings at rated engine speed, while the fuel model developed was formulated based on the field operation of a Massey Ferguson 3060 tractor at reduced engine speed. Potential savings in fuel consumption of up to 20% could be obtained when operating a tractor at part load and reduced engine speed (Schrock et al, 1986;Chancellor and Thai, 1984;Grogan et al, 1987;Smith, 1993). The ASAE Standard Equation gave a predicted magnitude of fuel consumption 15% higher than the actual measured magnitude for the tractor.…”

“…Operation efficiency can be improved by maximising the work output or reducing fuel consumption. Potential savings up to 20% could be achieved with the gear-up throttle-down technique (Chancellor and Thai, 1984;Schrock et al, 1986;Grogan et al, 1987;Smith, 1993). The proper matching of an implement to a tractor is another method of increasing operational efficiency.…”

“…By analyzing the effect on the relationship between the specific fuel consumption with tillage depth and the engine load level of the tractor, the effect of tillage depth on fuel efficiency can be analyzed. Therefore, the analysis of the fuel efficiency of a tractor is generally expressed using specific fuel consumption (SFC) [45,46]. In overall mean values, the maximum SFC was 302.44 ± 6.04 g/kWh at 11 cm and minimum SFC was 236.93 ± 6.41 g/kWh at 23 cm, which was 21.7% lower than maximum value.…”

In order to optimize tractor design and optimize efficiency during tillage operation, it is essential to verify the impact through field tests on factors affecting the tractor load. The objectives of this study were to investigate the effect of tillage depth on power transmission efficiency of 42 kW power agricultural tractor during moldboard plowing. A load measurement system and a tillage depth measurement system were configured for field tests. To analyze the effect of tillage depth on power transmission efficiency and fuel consumption, the data measured in the three-repeated field test were classified according to tillage depth. As the tillage depth increased from 11 cm at the top of the hardpan to 23 cm at the deepest, the required power of the engine increased by approximately 13% from 35.48 kW to 40.11 kW, and the power transmission efficiency also increased significantly from 66% to 95%. Among them, the power transmission efficiency of the rear axle was significantly increased from 38% to 59%, which was the most affected. As the tillage depth increased, the overall power requirement is greatly increased due to the resulting workload, but the fuel consumption and the specific fuel consumption are reduced because the engine speed of the tractor is reduced. As the tillage depth increased from 11 cm to 23 cm, the fuel consumption rate was rather reduced by 13.5% as the engine rotational speed decreased 11.3% due to the increase work load of tractor. In addition, the specific fuel consumption decreased from 302.44 g/kWh to 236.93 g/kWh, showing a fuel consumption saving of up to 21.7% during moldboard plow. In addition, as the tillage depth increased, the ratio of the value excluding the mechanical and hydraulic power requirements has significantly decreased from 34% to 5% as the power transmission efficiency increases. This study considers the soil properties according to the soil depth, as well as the power transmission efficiency and fuel consumption rate. The research results can provide useful information for research on power transmission efficiency and selection of an appropriate power source of agricultural tractor according to tillage depth during moldboard plowing and are expected to be used in various ways as basic studies of digital farming research in agricultural machinery.

“…Lister (1985) performed GUTD on 16 tractors in a limited amount of load which fuel consuming decrease fairly from 9 to 18%. Grogan et al (1987) developed an instrumented tractor with an on-board microcomputer to measure engine load, engine speed, wheel slip, fuel consumption, draught, and hitch forces. The analysis indicated that farmers could have reduced fuel consumption up to 15-27% by practicing "shift-up, throttle-back"; i.e.…”

Machinery traffic on farm and forest caused to problems in environment and economics by Fossil fuel consumption and soil compaction. According to result of investigation, The GUTD (Gear Up and Throttle Down) method was recommended to decrease fuel consumption. But the wide range of machinery applications, soil conditions and experience of drivers or operators need to have index for ensuring the GUTD method is carried out properly. The purpose of this study was evaluation of GUTD method using MF 399 tractor on instantaneous fuel consumption and soil compaction. The tractor was equipped by sensors, a designed electronic circuit and a computer to measure and record parameters such as fuel consumption, forward speed and wheel slip. This field examination was carried out on tilled land with clay-loam soil and then data were analyzed in a randomized complete block design with three replications. Considered factors were included four speed levels (1.6, 3.2, 6.4, 12.8 km·h -1 ), three levels of gear (first, second and third) and two levels of wheel drive (2WD and 4WD). Parameters of cone index and bulk density were used to determine soil compaction.Variations in compaction of before and after tractor passage were calculated in each plot. Statistical analysis in each speed showed that factor of gear in variations of soil compaction was significant at all speeds except 12.8 km·h -1 and instantaneous fuel consumption was reduced by GUTD at each of constant speed except the mentioned speed. This research showed that instantaneous fuel consumption can be considered as appropriate index for selecting the best gear and speed in terms of fuel consumption and soil compaction.
