7.2.2 OPERATION MODULE
In SECA, all the agricultural machinery are categorized into five farming
related operations (o1~o5, Table 1). These operations include mechanized
tillage, mechanized sowing, mechanized harvesting, mechanized irriga-
tion and other operations. They are assumed as follows:
• Mechanized tillage (o1) and mechanized sowing (o2) are performed by
tractors and associated towing farm machinery. Both the large and medium-
sized tractors and the small ones are included.
• Mechanized harvesting (o3) is performed by combine harvesters, swathers
and other harvesters.
