Determination of Draft Power, PTO Power and Fuel Consumption of Single Acting Disc Harrow Driven from PTO

Abstract

In this study; A single-acting disc harrow is used, which takes its movement from the tractor PTO. PTO driven single-acting disc harrow was tested with disc diameters of 610 and 660 mm, disc direction angles of 160 - 230 and 300, and disc revolutions of 104.97 - 119.97 and 143.96 min-1. Single-acting disc harrow moving from PTO was compared in terms of disc diameter, directional angle and disc revolutions. The lowest draft force requirement was obtained from D1N1Y1, D2N1Y1 and D1N1Y2 applications, with values of 0.48 kW, 0.61 kW and 0.79 kW, respectively. The highest draft power requirement was obtained from D2N3Y3, D2N3Y2 and D1N3Y3 applications with 7.80 kW, 6.97 kW and 5.25 kW values, respectively. The lowest PTO power take-off power requirement from the applications was obtained from the D1N1Y1, D1N2Y1 and D1N3Y1 applications, with values of 22.80 kW, 22.88 kW and 24.82 kW, respectively. The highest PTO power take-off power requirements were obtained from the D2N3Y3, D1N3Y3 and D2N3Y2 applications, with power requirements of 41.15 kW, 39.40 kW and 38.62 kW, respectively. In terms of fuel consumption, the lowest fuel consumption was determined in D1N1Y3, D1N1Y2 and D1N1Y1 applications with 11.40 L ha-1 11.63 L ha-1 and 11.95 L ha-1 values. The highest fuel consumption was obtained from 18.34 L ha-1, 17.78 L ha-1 and 17.58 L ha-1, respectively, and D2N3Y3, D2N3Y2 and D2N3Y1 applications.
