The operations of farming for which machines are used are diverse. For crop production they include handling of residues from previous crops; primary and secondary tillage of the soil; fertilizer distribution and application; seeding, planting, and transplanting; cultivation; pest control; harvesting; transportation; storage; premarketing processing; drainage; irrigation and erosion control; and water conservation.
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.
