ABSTRACT

Two common harvesting methods, stripper header and conventional header were studied economically. Wheat harvest operations, cutting residual stems on the field, Rake then packing for stripper field and wheat harvest, rake operations and also without rake then packing for conventional header were compared. To obtain harvest costs, all parameters affecting on harvesting was measured and calculated. Results showed that residual straw on the stripper field was so minimal and next tillage operations can be done easily. Harvest speed with stripper header was 41% more than conventional. Fuel consumption in wheat harvest with stripper header 5.68 l∙ha^-1 has decreased and for collecting straw has increased 23.53 l∙ha^-1 than conventional header. Net income from conventional harvesting with rake operations has increased 30% and 35% without rake operation. Totally harvesting income with stripper header 307 000 tom (1100 tom = 1$) and 344 000 tom per hectare was more than conventional header with rake and without rake operation.

Key words: harvesting income, collecting straw, rake, stripper header, combines.
