| ABSTRACT: The correct choice of modern power transmissions can help farmers decrease production costs. The following research aimed to assess fuel consumption efficiency of an agricultural tractor equipped with continuously variable transmission, at different travel speed and load levels applied on the tractor drawbar. Standard procedure has been applied considering six load levels (30; 40; 50; 60; 70 and 80% of Q0) by means of breaking with a dynamometer car instrumented in a concrete test track, at three travel speeds (5.16; 7.29 and 10.48km h-1). Throughout the experiment, engine speed, traction force and hourly fuel consumption were monitored. The results indicated that there was an average increase of 2.67; 2.82; and 2.61L h-1 in the hourly fuel... |

| ABSTRACT During the acquisition and use of an agricultural tractor, the consumption of fuel by the engine must be taken into account by the user, considering its nonrenewable origin and the marketing price. Appropriate strategies in driving tractors can help users to reduce production costs. In this context, the objective of this study was to evaluate the fuel consumption of an agricultural tractor using different driving strategies. Load levels were imposed, following the instructions from Organization for Economic Co-operation and Development Code 2, using an instrumented dynamometer car, in a concrete test track. Six load levels (30, 40, 50, 60, 70, and 80% of Q0) and three travel speeds (5.16, 7.29, and 10.48 km h-1) were applied for the strategies... |
