“…To support such strategies in smaller farms, knowledge and technology extension services led and promoted by government, universities, and innovative platforms (e.g., Science and Technology Backyard, STB, Zhang et al, 2016) should exist for different farm sizes. For instance, in regions increasing farm sizes, matching the expansions in farm size with larger and scale‐appropriated machines will be critical for sustainable maize production (Aguilera et al, 2019; Janulevičius et al, 2019). In addition, other strategies including agricultural professional cooperation, credit services, insurance, and laws safeguard ownership to improve the willingness of farmers like in France and United States should also be attached an importance.…”

While the relationship between crop yields and the environmental impacts of crop agriculture has been well‐documented, research on the relationship between farm size and the sustainability of cereal production is limited. Using survey data on 120 farms with both small‐ and large‐scale fields in Northeast China, this paper combines a life cycle assessment and the carbon‐based sustainability index (SI) algorithm to examine how maize productivity and agricultural inputs vary with farm size and to clarify how increasing farm size is correlated with energy use efficiency (EUE) and the SI. The results indicate that maize grain yield did not vary with farm size. Increasing farm size was shown to lead to reductions in the areal (per ha) rates of agro‐chemical inputs, energy depletion, and greenhouse gas emissions and increased in EUE and SI. Fertilizer‐ and fuel‐related agricultural inputs dominated the variations of EUE and SI. A scenario analysis indicates that, if farmers adopt a comprehensive management strategy (i.e., machines appropriate to farm size and recommended fertilizer application rates and crop management strategies), EUE and SI would increase by 68.5% (from 4.45 to 7.50) and 74.3% (from 10.1 to 17.6), respectively. Although increasing farm size could benefit maize sustainable production when matched with technical innovation and machinery coordination, supporting smallholder farmers to increase their resource use efficiency and sustainability is also key in China and other regions where smallholder farms comprise a large portion of the cropland area.

“…In the ER variable, there is no significant difference in the MDBA (Table 1), remaining constant, even with the increase in DBF (MC gear). The HFC also did not differ in the compared MDBA, being explained due to ER and SLP because they do not differ significantly, corroborating Mamkagh et al (2018) and Janulevičius et al (2019). However, there was a significant difference in the different gear shifts, resulting from the other gear ratios (McLaughlin et al, 2019).…”

The traction efficiency of the agricultural tractor can be maximized by adjusting the total mass and its distribution between the axles. The experiment’s objective was to determine the configuration of mass distribution between axles and the displacement speed that provides greater traction efficiency in the harrowing operation. A randomized block design in a 2 × 3 factorial scheme with five replications was used. The first factor was two mass distributions between axles, and the second factor was three gears. The collected data were submitted to analysis of variance and the Tukey test. The condition that maximizes the tractor’s performance corresponds to 39% of the total mass on the front axle and 61% on the rear axle, with a gear that provides speed close to 10 km h-1.

“…Therefore, tractors consume a large amount of energy by burning fossil fuels in the engine that converts thermal energy to mechanical energy for pulling and rotating the tillage implements. Emissions of greenhouse gases through the burning of fossil fuels in the tractor engine during cultivation process are the main source of Agronomy 2021, 11, 168 2 of 16 environmental contamination and global warming as CO 2 mainly emitted through fossil fuels burning [2,[4][5][6]. If the use of fossil fuels and consequently CO 2 emissions continued at their current rate, massive climate changes will be possible [7][8][9].…”

“…By improving the operational efficiency and productivity of farm tractors with the lowest possible tractor weight can help to reduce energy consumption [11,19,20]. It is necessary to select the equipment and configuration of the tractor and tillage implements and travel speed of tractor optimal for intended field tillage operation [2,4]. Efficient operation of farm tractors in tillage operations includes; (1) fuel efficiency of the engine, (2) power transfer efficiency of the drivetrain and (3) power transfer efficiency of the traction device/drive gear (wheels and tracks).…”

Farm tractors in cultivation consume a big amount of fossil fuels and emit greenhouse gases to the atmosphere. Improving traction performance and power transfer indices of wheeled tractors and field terrain soil with higher traction (pull ability) at optimal travel reduction (TR) can optimize energy utilization. This study compares the traction performance, fuel consumption, and field productivity, of a farm tractor equipped with a new drive wheel “rigid lugged wheel (RLW)” and conventional tire wheel (CTW) in field tillage operations. Tractor with RLW resulted 24.6 kN drawbar pull and 6.6 km.h−1 travel speed at 80% tractive efficiency and 15.6% TR. While with CTW, the drawbar pull and the travel speed were 23.2 kN and 6.0 km h−1 respectively at 68% tractive efficiency and 36.3% TR. The RLW resulted in improved traction performance with similar equipment weight. Tractor with RLW also resulted 220.5% lower TR, 14.8% higher field productivity, and 15.4% lower fuel consumption. RLW can control equipment weight and field traffic intensity with the improved traction performance of wheeled tractors and will make the field operations more energy-efficient and economical. For enhanced field drivability of RLW, further work is required to test for diverse field conditions and differently sized tractors.
