چکیده	The price of fuel has a big effect on the cost of farming inputs, especially during the first stage of planting. It depends on a lot of things, like the speed of the tractor, the depth of the plowing, and the type of plow. In June 2022, the test was done in the soil hall of the University of Diwaniyah's College of Agriculture. We used a Massey Ferguson 8480 4WD tractor to find out how much fuel was used (l/ha) and how well the tractor worked with moldboard and disc plows. The test was done on sandy loam soil with a moisture content of 11.73% and a dry bulk density of 1.35g/cm3. Depending on the type of plows, the tractor's plowing depth was set between 15 and 20 cm, and its forward speed was set between 5 and 7 km/h. The findings indicated that when using the disc plow, approximately five percent more fuel was consumed than when using the moldboard plow. When traveling at 7 kilometers per hour with a tractor, approximately 8% less fuel is consumed than when traveling at a faster speed. The reduction in fuel consumption was approximately 34% when the depth of the plow was increased from 15 cm to 20 cm. The amount of power required to operate a moldboard plow was approximately 14% higher than the amount of power required to operate a disc plow. When traveling at 7 kilometers per hour, approximately 27% more power was required than when traveling at 5 kilometers per hour. The amount of energy required increased by approximately 1.5% when the depth of plowing increased from 15 cm to 20 cm.
