“…The YDB demonstrates the use of the engine power in the drawbar, considering the DS and DBF that the tractor is pulling. The DS did not present any interaction between the parameters analyzed; therefore, this fact is explained by the tractor in the MDBA 39%/61% show greater mass in the rear axle, hence greater DL, consequently, traction greater DBF, as described by Lankenau et al (2018), thus promoting greater PDB that directly provides greater YDB, justifying the results found in the configuration 46%/54% in the MA, MB, and MC gears had been lower. MA -A gear; MB -B gear; MC -C gear; Means followed by different uppercase letters in the rows and lowercase letters in the columns differ by the Tukey test at p ≤ 0.05…”

“…The factors that interfere in the efficiency of the set (tractor + implement) such as displacement speed (Jasper et al, 2016), mass distribution between axles (Peeters et al, 2018) and its total mass (Lankenau et al, 2018), directly imply operational and energy efficiency. When there are no assertive adjustments to the factors mentioned above, mechanized assemblies' operational and energy performance are impaired (Lopes 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.

“…The introduction of farm tractors is a good example and an important step in the modernization process of this sector, and is being considered one of the greatest advances in the agricultural sector [ 4 ]. This type of machinery accelerates the execution of many tasks, increasing productivity and enabling the agricultural exploitation of new crops, thus promoting competitiveness and business opportunities.…”

A Solution to Prevent and Minimize the Consequences of Accidents with Farm Tractors in the Context of Mountainous Regions with Low Population Density

Farm tractors have become a key part of daily routine agriculture, converting complex and time-consuming tasks into tasks that are easier to perform and less dependent on human labor, contributing directly to increasing the economic value generated by this activity sector, either by increasing the productivity or by making certain agricultural crops viable, which otherwise would not be sustainable. However, despite all the advantages, accidents with this type of equipment are common, often with critical and sometimes fatal consequences. The evolution of safety requirements of these machines has occurred at a good level; however, a significant part of the agricultural tractors in use are older models that do not have such solutions. Even in the new models, which contain such solutions, these are not always correctly used, and it is even common that they are turned off or simply not used at all. It is therefore natural that accidents continue to occur, a situation that is aggravated by other factors. Lack of situational awareness of the operators, which can result from advanced age, inadequate training, reduced sensitivity/respect for safety rules, or working on irregular terrain like mountainous areas, contribute to high-risk contexts that end in the loss of human life. The consequences of such accidents are clearly aggravated by the time it takes to assist the victims—either because accidents are simply not identified/reported immediately, or by the time it takes to locate and provide help to the victims. This is a scenario that is more common in mountainous regions and regions with low population density. The current paper, using NB-IoT, a set of sensors, and a web application, presents a conceptual toolset conceived to prevent accidents and minimize consequences (human and material) that can be applied to old and new farm tractors. The development was carried out taking the characterization of the farmers and the land in the region in which the authors’ research institution is located into account, which has the highest rate of fatal accidents with agricultural tractors in the country; it is a region of mountainous with a very low population density.

Interference of the Number of Remote Control Valves in Use on the Energy Performance of an Agricultural Tractor With Productivity Management

et al. 2020

The hydraulic remote control system allows the transfer of energy from the engine through a flow of hydraulic oil to engines and implements pulled by agricultural tractors, which can interfere with its energy and operational performance. This study aimed to evaluate the interference of the number of remote control valves in use on the operational and energy performance of an agricultural tractor, using a productivity management system. The experiment was conducted in a strip-plot design, with five replications and three treatments, which consisted of the number of remote control valves in use (1, 2, or 3), totaling 15 experimental units. The results were subjected to normality and homogeneity tests and analysis of variance, followed by the Tukey test when it was significant. The highest number of valves in use interfered with the operational speed, power and efficiency on the drawbar, specific fuel consumption, and engine thermal efficiency, thus reducing the energy and operational performance of the agricultural tractor.
