A. Bianchini et al., TRACTION PERFORMANCE OF AN AGRICULTURAL TRACTOR (2-WD) ON ALLUVIAL SOIL, Pesquisa agropecuaria brasileira (1977), 33(8), 1998, pp. 1425-1430
The objective of this research was to evaluate the performance of an a
gricultural tractor 2 WD, on Alluvial soil. The experimental design ad
opted was a factorial (3x2x2), with three levels of soil moisture (36.
3, 41.7 and 49.1%), two vegetation covering amounts and two working de
pths, with three replications. Soil moisture of 36.3% presented the hi
ghest risk of compaction. The tractive efficiency showed significant d
ifference among moisture levels only for 33.1 cm depth, in the presenc
e of 3,690 kg/ha of vegetation covering. Work depth influenced all par
ameters studied in the evaluation of tractor performance.
