Abstract
The study was conducted during the year 2008 in two phases, the first phase in laboratories of the Agricultural Mechanization Department, Faculty of Agriculture and Forestry, University of Mosul, through which access to bio-fuels (Bio-diesel) oil extracted from corn through a number of laboratory operations achieved to remove water from the Glycerin and corn oil for use as a fuel of farm tractor, and the second phase is the evaluation field, where the experiment carried out using the global random sectors full RCBD and three repeaters, adopted by the first factor with three types of fuel levels (diesel fuel (Gas-oil) 100%, 50% diesel fuel + 50% bio-fuel, 100% bio-fuel) The second factor is three levels of tillage speeds (2.16, 4.5, 6.3) km/hour, with the following attributes were examined: fuel consumption, Lost power by slippage , draw power , specific soil resistance, Efficient use of energy, Field efficiency, the results showed that the diesel fuel 100% gave higher capacity and higher resistance to the withdrawal of the quality of the soil and less efficient use of energy, and the speed 2.16 km / h gave higher fuel consumption and more efficient use of energy in the given speed while the 6.3 km / h higher ability to slip and lost the ability to withdraw the highest quality and resistance of the soil, and diesel fuel 100% was given at the speed of 6.3 km / h higher capacity, while at the withdrawal of bio fuels 100% has been given speed 2.16 km / h more efficient use of energy.
