Abstract

An experiment in the fields of the faculty of agriculture university of Baghdad in Abu-Ghraib for the impact of moisture content and depth of tillage in some performance indicators for the unit gained (tractor-plow) and qualities that have been studied is to calculate the towing capacity and drag force and the percentage of slipping and consumption fuel.The results indicate that when increasing soil moisture led to an increase in the percentage of slipping and also led to an increase in fuel consumption and towing capacity as well as to low soil moisture without a degree althely led to an increase in the proportion of same qualities the study found that when increasing the depth of tillage led to high in the percentage of slip and fuel consumption and towing capacity and traction.Put down deep tillage led to the low percentage of slip, fuel consumption and towing capacity and drag force and calculated in this research that best combination obtained are when you use the content moisture of the soil between (11.13%) with use of deep plowing (12-15) cm where to get the lowest rate of towing capacity amounting (8.4) hp and less powerful pull of amounting (940.1) kgf and less fuel consumption and of (50.8) L.ha and the lowest percentage of slip and amounting (4.6%)
