Using state-of-the-art technology, a well-maintained combine harvester operated effectively in a mature crop, can attain clean grain recoveries of 99 % – a remarkable achievement! Work rates in excess of one hectare (10 000 m 2 ) per hour are readily achievable with two operators, one to drive the combine, the other to drive a tractor-trailer or a truck into which the combine periodically empties its grain for transportation to the farm granary or direct to the local grain merchant or storage facility.

This paper discusses the history of mechanization, the major reasons for the wide diversity observed, the options for developing countries in extending mechanization, and the role of government policy in influencing the choice of technology.
