Abstract

In this research, the effect of tillage depth and progressive speed on cultivating operation was investigated on fuel consumption, tensile strength and soil fragmentation by flat gas grass blade. Field experiments were conducted on sandy loamy soil at Ardebil Agricultural and Natural Resources Research Station. The experiments were carried out in a factorial design with RCBD (RCBD) in three replications. The blade was tested by a Gaussian knife blade tested at three levels (3, 6.5 and 9 km / h) at the tractor speed, the depth of work at two levels of 10 and 20 cm. In each plot, the soil moisture content was measured. In this research, with regard to the development, application and high accuracy of the Abagos software in prediction, the Abagos / Exxpelite was used to predict its force and vertical force on the cultivator blade blade. The results of both methods showed that the dual effect of work depth and forward speed and depth of work on tensile strength and vertical force were significant and with increasing of these factors the forces on the blade increased.
