“…Many national and international research projects are currently focusing on the above aspects in order to develop and promote new strategies oriented towards improving agricultural sustainability. In this context, also the optimisation of the interaction between soil and agricultural vehicles is recognised as one of the major future challenges, as it is demonstrated how such aspect might easily turn out in a substantial decrease in fuel consumption and soil compaction (Battiato, Diserens, & Sartori 2014;Battiato, Alaoui, & Diserens, 2015;Battiato & Diserens, 2017). Within this framework, it is of certain interest to analyse and simulate the role of the soil in conditioning the traction performance, with particular regard to the fuel consumption, of an agricultural tractor.…”

“…A major interest focused on the possibility to improve the traction performance of a tractor by optimizing its configuration in terms of tyre inflation pressure, number of drive wheels and load acting on the wheels (Burt Bailey, Patterson, & Taylor, 1979;Burt & Bailey, 1982;Charles, 1984;Turner, 1993;Zoz & Grisso, 2003;Damanauskas, Janulevičius, & Pupinis, 2015;Battiato & Diserens, 2017). However, this aspect can't disregard the nature of the soil on which the tractor moves as well as the soil condition and the presence of vegetation, particularly post-harvest stubble.…”

This study aimed to investigate the influence of the mechanical behaviour of the soil surface on the traction performance and the fuel consumption of an agricultural tractor, both in qualitative and in quantitative terms, in order to increase the consciousness about the major role of the soil mechanical response in the optimisation of the energy aspects involved in the traction developed by a tractor and promote the development of new strategies to reduce costs of tillage management and improve agricultural sustainability. The traction performance of a 65 kW MFWD tractor at tyre pressures of 60 and 160 kPa was compared on four Swiss agricultural soils: a clay with corn stubbles, a clay loam with wheat stubbles, a silty loam and a loamy sand both with corn stubbles. Tests performed with a bevameter pointed out noticeable differences in the mechanical behaviour of the soils. According to such differences, the drawbar pull on the four soils was significantly disparate with differences in maximal values of about 16% at a tyre pressure of 60 kPa and up to 37% at a tyre pressure of 160 kPa. Simulations with a semi-empirical tractor-soil interaction model also showed dissimilarities in traction coefficient, motion resistance, and traction efficiency. Measurements of the fuel consumption pointed out the presence of a narrow slip range where the specific fuel consumption SFC is minimised. This range doesn’t vary significantly among the considered soils as well as with the tyre pressure and doesn’t differ very much from the range where the power delivery efficiency is maximised. The SFC differed for almost 20% among the considered soils at a tyre pressure of 60 kPa and for ca. 10% at a tyre pressure of 160 kPa. The increase in tyre pressure from 60 to 160 kPa produced an increment in SFC up to 16%. The results of this study clearly pointed out how the traction performance is a characteristic of the tractor-soil system and not of the tractor only, therefore, a proper knowledge of the soil mechanical behaviour should aid in developing strategies oriented towards reducing fossil fuel consumption.

“…There are tools or applications to predict the risk of soil compaction for a specific field operation. These are, for example, the REPRO- [35,36], the Terranimo- [37], or the TASC-model [38]. All of them are working with the precompression stress concept, which should not be discussed further in this place; instead we refer to other work [16,[39][40][41].…”

A Multi-Data Approach for Spatial Risk Assessment of Topsoil Compaction on Arable Sites

et al. 2018

Soil compaction is a human-induced threat which negatively affects soil functions and is highly dependent on site-specific soil conditions and land use patterns. Proper management techniques are indispensable for sustainable soil protection to ensure its function in the long term. A number of concepts exist to develop risk maps on the basis of soil inherent susceptibility to compaction at a given soil moisture level (mostly field capacity). However, the real soil conditions, e.g., current soil moisture content at the time of field work and the real machinery load, are not taken into account. To bridge this gap, we present a multi-data approach for qualitative risk assessment, which combines spatially and temporally explicit data on soil, soil moisture, and land use information. The contributing components integrate daily probability distribution, including inter- and intra-annual variations in land use and weather. We combined soil susceptibility to compaction and field work for the federal state of Lower Saxony per half-months and identified three clusters with more or less compaction risk for Lower Saxony. In spring, mainly manure spreading to maize and in autumn harvesting of maize and sugar beets are contributing to the yearly probability of compaction risk in top soils. With the presented approach risk areas can be identified. For the evaluation of the current compaction risks, farm specifications on machinery and timing of field work must also be taken into account.

“…It depends mainly on soil and tyre deformation. Rolling resistance influences the value of slip, therefore, determines the wheel slip in connection with rolling resistance and it is important for thrust [12]. We can calculate the depth of ruts, remaining in the wheel track; this depth depends on the soil state and bearing capacity.…”

Abstract. Tractors usually are designed to pull the implements in fields. The resistance force of the implement is proportional to the wheel adhesion with soil and depends on the soil conditions, where tractor wheels interact with the soil surface. The part of the tractor's power is lost during the process of interaction between the tires and the soil surface. The tire pressure and vertical wheel load are easily managed parameters, which have an influence on interaction between the tires and the soil surface, the tires and soil deformations and the tractor fuel consumption. Tire deformation is reversible and permissible, but soil deformation is almost irreversible and undesirable. Soil deformation increases the soil density and in this case plants have unfavourable conditions to grow. The studies have shown that the weight of a tractor should be small in wet viscous soil conditions, because then the enlargement ballast weigh increases soil deformation. In this case, the tractor may not be able to develop maximum traction, as its engine energy is used to overcome the moving resistance. Tractor fuel consumption in viscous soil conditions was reduced by reducing soil and tire deformations. It was achieved by doubling the wheels and selecting the air pressure in tires. The aim of this research is to evaluate the energy and environmental aspects of a tractor with single and double wheels to determine the energy efficiency in case of soil and tire deformation.
