OPERATIONAL AND ENERGETIC PERFORMANCE OF AN AGRICULTURAL TRACTOR DURING DIRECT AND CONVENTIONAL SOWING
The aim of this work was to evaluate the operational performance of a tractor and precision planter-fertilizer set during corn sowing, under three displacement speeds: 3.0, 5.0 and 8.0 km h-1 (0.83, 1.40 and 22.2 m s-1) and two kinds of sowing – direct and conventional. The design used was on random...

| Summary: | The aim of this work was to evaluate the operational performance of a tractor and precision planter-fertilizer set during corn sowing, under three displacement speeds: 3.0, 5.0 and 8.0 km h-1 (0.83, 1.40 and 22.2 m s-1) and two kinds of sowing – direct and conventional. The design used was on randomized blocks, in a 3x2 factorial arrangement, with three repetitions for each treatment. Data was gathered on tractor average traction power; average power on tractor drawbar; performance on drawbar; effective field capacity; field efficiency; hourly fuel consumption; specific fuel consumption; operational fuel consumption; energetic fuel consumption per area; slip of wheelsets and longitudinal distribution of seeds. It was observed that displacement speed influenced the variables: power on tractor drawbar; performance on drawbar; hourly fuel consumption; specific fuel consumption; operational fuel consumption; effective field capacity; field efficiency; slip of wheelsets and longitudinal distribution of seeds. |
