The general objective of this study was to investigate the performance of the tractor with different implements with variable loads and speeds. The soil texture was found to be clay loam. The result shows that; the highest fuel consumption was at engine speed 2000 rpm which was 9.55 liter per hour. This was followed by 1500 rpm (7.67 L/hr.) and 1000 rpm (6.98 L/hr.). And also for all loads range and gear levels fuel consumption and velocity increased. The obtained results show as the weight range from 0-1000kg increases drawbar pull increases from (13.57-23.82KN) and forward speed decrease (4.49-2.39 km/hr.). The results showed that the effective field capacity increased by increasing the traveling speed of the tractor, but the field efficiency decreased with the increase of traveling speed from 3.33% to 2.00% which may be due to the increase in the theoretical field capacity for 500kg weight implements. For 1000kg weights the effective field capacity and theoretical field capacity decreased by increasing the traveling speed of the tractor, but the field efficiency decreased with the increase of traveling speed.
