This paper examines the availability and reliability of Tractor FIAT of 115/08BT in Agip Farm, in the Green River Project Omuku in Rivers State, Nigeria. Tractor FIAT 115/08BT model from Agip Farm was used. A period of 7 years (1999- 2005) was considered. Parameters such as time to repair (MTTR), mean time between failure (MTBF), failure rate (), repair rate (), availability (A) and reliability (R) were calculated and data obtained used in plotting availability and reliability graphs. The computed results from these data were below the recommended benchmark and workshop maintenance best engineering practice. Problems for low availability and reliability of the tractor were traced to lack of adequate maintenance policy, adequate funding and involvement of in-experienced operators. However, a better form of proactive maintenance policy and strategies were recommended such as reliability centred maintenance and total productive maintenance.
