Abstract

This study was done to evaluate energy demand of a prototype subsoiler with expander to insert porous materials into drains. The study was done in an experimental area of the Federal University of Viçosa, Viçosa-MG. Fuel consumption and power requirement were measured using rice hull as the test porous material. The experiment was done with three replications in the factorial design, consisting of two speeds and four depths. The clayey soil profile was characterized as red-yellow podzol. The maximum force demanded by the prototype was 13711.1 N with maximum power of 17.85 kW. at the speed of 4.9 km.h-1 and the depth of 0.60 m. The mean force required by this prototype was lower than that reported in the literature. The average power required by the subsoiler was 9.98 kW, and that of the tractor-prototype combine was 12.26 kW. The tensile strength / work depth ratio was within the limits established by ASAE for clay soils.
