Traction performance of an agricultural tractor (2 WD) on Alluvial soil

Abstract

The objective of this research was to evaluate the performance of an agricultural tractor 2 WD, on Alluvial soil. The experimental design adopted was a factorial (3x2x2), with three levels of soil moisture (36.3, 41.7 and 49.1%), two vegetation covering amounts and two working depths, with three replications. Soil moisture of 36.3% presented the highest risk of compaction. The tractive efficiency showed significant difference among moisture levels only for 33.1 cm depth, in the presence of 3,690 kg/ha of vegetation covering. Work depth influenced all parameters studied in the evaluation of tractor performance.
