Abstract

FRANTZ, Ulisses Giacomini et al. Energy efficiency of a tractor using two configurations of power take-off. Cienc. Rural [online]. 2014, vol.44, n.7, pp.1219-1222. ISSN 0103-8478.  https://doi.org/10.1590/0103-8478cr20130175.

The agricultural tractor power take-off main purpose is to transmit the power generated in the engine to drive the active organs of farm machinery. In view of the need to increase the energy efficiency in agriculture, some manufacturers provide for farmers a power take-off with economy mode, which provides to the drive these machines at a reduced engine rpm. Thus, the PTO speed is maintained and can obtain a reduction in fuel consumption. This research aimed to quantify the fuel consumption of a tractor with two power take-off configurations in two agricultural areas with different reliefs. As result, it is evident that the use of economy mode, both hourly fuel consumption and operational fuel consumption in both areas worked less when compared to standard power take-off.

Keywords : fuel consumption; economy PTO mode; machines driven by PTO.
