Analysis of Traction Properties and Power of Wheels Used on Various Agricultural Soils

Abstract

The paper presents results of the research on traction properties of two tractor tyres used on two agricultural grounds. The first ground was a stubble and the second one cropland. The investigated tyres had the same structure (diagonal, with a traditional tyre tread but different external dimensions. The research was carried out in field conditions with the use of a stand aggregated with a farm tractor. Analysis covered traction efficiency, slide, towing power and power lost on the rolling resistance and wheel slide. Based on the obtained results it was concluded that on a ground with lower compaction, the values of power losses were higher and traction efficiency was lower. Moreover, it was proved that the value of the power lost for rolling resistance had a decisive impact on the values of traction efficiency

Detrimental Effects of Induced Soil Compaction on Morphological Adaptation and Physiological Plasticity of Selected Multipurpose Tree Species

“…Since the overall porosity of the soil decreases as a result of soil compaction, the water penetration rate in the soil may be used to determine soil compaction [53]. Water penetration is weaker in extremely compacted soil than in uncompacted soil in the same soil type [54]. Moreover, moderate compaction of coarse-textured soil generally improves root contact with soil, which helps in better nutrient absorption [6,55].…”

Assessment of the Performance of Agricultural Tires Using a Mobile Test Bench

“…It houses diagnostics equipment that enables the measurement of traction, drawbar pull, wheel slip, bar tear, and overall tire strength [21]. Czarnecki et al [22] developed a test stand mounted on a two-part frame suspended on a three-point suspension linkage of a tractor. The tested wheel was mounted on a shaft and the wheel drive was obtained from the power take-off shaft through a reducing gear.…”
