Available at (http://41.86.178.3/internetserver3.1.2/detail.aspx)http://localhost:8080/xmlui/handle/123456789/241Available in print formThe study aimed at investigating the actual and potential performance of agricultural machinery in the field, taking Kilombero sugar Estate as a case study. The study revealed out that service ability at Kilombero Sugar Estate was affected mainly by the nature of duties on which the tractors were employed. Service ability ratios of 82% for field and cane transport tractors were observed. As expected service ability decreased to a small extent, with season (approximately 1% per month). The achieved levels of service ability were high and much better than those recorded on some schemes else where eg. In Ghana. Nevertheless these a figure could be improved by: close attention to routine servicing particularly of items with known liability to damage such as the near when hubs and bolts of newer models of tractors; improve spares availability, improve workshop equipment, and employment of more skilled mechanics, possibly achieved through a formalized programme of an the job training. It would seem reasonable to aim at a serviceability ratio of 90% for field operations.enAgriculture machineryKilombero sugar estateTanzaniaThesis
