“…Tests carried out by Siddique et al (2023) on an agricultural tractor with the power-shift transmission in traditional driving mode, Power and ECO during plow tillage, rotary and asphalt conditions showed excellent fuel economy to ECO mode for all field conditions. The results showed savings between 44.7 and 21.4% (asphalt), 25.9 and 19.6% (plow tillage) 42.4 and 28.4 (rotary tillage) for ECO mode compared to Power and Power mode compared to traditional, respectively.…”

Sugarcane is one of Brazil's leading crops, and the transshipment harvesting operation represents a significant portion of operating costs. Among the primary machines used in harvesting is the tractor-transshipment set, with considerable energy demands. This study focused on evaluating the gear selection effect in an agricultural tractor on operational performance and costs during the sugarcane transshipment operation. The treatments consisted of four operational work gears at different engine speeds: r1 -1150 rpm, r2 -1230 rpm, r3 -1360 rpm, and r4 -1500 rpm on the engine. The analyzed variables were volumetric and specific fuel consumption, operational efficiency, and operational cost. The variables were adapted from ASABE (2011) methodology, and the data were submitted to parametric statistics and regression analysis. The rotation engine selection in tractors directly affected fuel consumption with positive angular coefficients and r2 between 0.92-0.96. Fuel consumption reduces by 37.5%, adopting 1150 rpm compared to 1500 rpm rotation. The highest rotation (1500 rpm -r4) increased the volumetric and productive fuel consumption, enabling savings up to reduced fuel cost by 1.08 US$ ha -1 . Thus, training sugarcane transshipment operators is essential to optimize the production process efficiency and reduce costs.

“…The fuel consumption in the APS ECO mode was 19.39 L/h. Siddique et al [19] conducted similar research and stated that the APS ECO mode was the most economical engine mode comparison with the conventional and APS power modes; it was around 42.35% more economical in terms of fuel than the conventional mode. However, it was observed that the conventional mode consumed the least fuel during rotary tillage.…”

“…Siddique et al [18] estimated fuel consumption based on the engine load levels by using a PTO (power take-off) dynamometer test and developed the simulation model using AMESim software (version 16, SIEMENS AG, Munich, Germany); the correlations were statistically analyzed and compared with those in the previous literature. Siddique et al [19] also stated that tractor fuel consumption highly depends on the load that occurs during agricultural operations and the gear stages used for the operations. In their study, fuel consumption was analyzed in both a simulation model and an experimental field test, and the results were statistically correlated.…”

The objective of this study was to estimate power delivery efficiency and fuel consumption based on engine modes. In this study, a 95 kW power-shift tractor was used to analyze power delivery and estimate fuel consumption during rotary tillage. Rotary tillage was conducted in a field experiment with the conventional, APS (auto power shift) power, and APS ECO engine modes. To analyze the field conditions, the soil hardness and soil water content were measured, and soil samples were collected from the experimental site to analyze the soil texture by using the USDA soil texture triangle. Finally, an efficient and suitable engine mode was selected for rotary tillage based on the working load. It was observed that the power delivery and tractive efficiencies when using the APS power mode were the highest among other engine modes, accounting for around 89.23 and 73.45%, respectively. However, the fuel consumption when using the APS power mode was approximately 23.02 L/h, which was also comparatively higher than that of the other engine modes. Additionally, the tractive efficiencies of each engine mode were compared using the Brixius prediction model. The statistical analysis of the predicted tractive efficiencies and those in the tests showed that there were no significant differences among the engine modes; this indicates that the APS controller could perform with high accuracy. In the conventional mode, the power delivery, tractive efficiency, and fuel consumption were approximately 66.48%, 55.89%, and 17.04 L/h, respectively, which were comparatively low. However, the slip ratio in the conventional mode was 18.80%, which was higher than that in the APS power and APS ECO modes. On the other hand, PDE, TE, and fuel consumption when using APS ECO were around 77.57%, 58.44%, and 19.39 L/h, respectively, which were higher than those of the conventional mode, but lower than those of the APS power mode. Furthermore, the comparative analysis showed that the working loads in the APS ECO mode were located in the ungoverned region and were very close to the engine’s maximum torque, which could allow sudden and unwanted engine turn-off due to the fluctuations in working loads, which is to be avoided. The fuel consumption was also comparatively low. However, the working loads in the conventional and APS power modes were located in the governed region, which was outside the engine’s operating range. Therefore, we recommend that users operate tractors in the APS ECO engine mode for rotary tillage, considering fuel economics and high working loads.
