This study was conducted in New Halfa Sugar Scheme to compare the actual and calculated power required in performing cultural operations, work rate of agricultural machines and the total operation costs of machines (implements and tractors) during the period 1994 – 2004. The results showed that the highest annual working hours in field operations was recorded by the up-rooting operation (2753.0 hr) and the least was recorded by the ridging operation (1192.0 hr). It was also noted that the highest fuel consumption rate was recorded in deep ploughing operation (8.6 gal/ fed) and the least was for ridging operation (2.3 gal/ fed). It was observed that the average actual power requirement was higher than that calculated by 28.4%. The average calculated rate of work/hour was higher than the actual by 53.9% and there were no significant differences between the different operations. The results indicated that track tractors gave higher working cost than tyre tractors with significant differences between tractors. The cost of ridger was the highest (4.74 $/hr) while the disc plough was the least (0.76 $/hr) with no significant differences between machines. The highest total cost of field operations was for deep ploughing and at 32% and the least for ridging at 6% with no significant differences in other operations.
