ABSTRACT
During harvesting season, often rain and storms occurs causing considerable damage to standing crops. Rapid harvest facilitates extra days for land preparation and earlier planting of the next crop. The use of machines can help to harvest at proper stage of crop maturity, reduce drudgery and operation time. Crops are harvested after normal maturity with the objective to take out grain, straw, tubers etc. without much loss. There are several methods of harvesting and threshing for wheat crop i.e. manual and mechanical method. Under this comparative study, the effective field capacity at 16 % moisture content was 0.30 ha/hr at speed of 3 km/hr. The field efficiency of self propelled binder was 74, 76.79 %, and 77.90 % at moisture content 20, 18, 16 % respectively. The shattering losses of self propelled reaper binder was 51 kg/ha at 3 km/hr forward speed with 20 % moisture content and observed that increase forward speed shattering losses was increase. The grain breakage percentage during experiment of combine harvester at 3.25 km/hr speed with 20 % moisture content was 0.06 % and observed that grain breakage percentage was increase with forward speed and moisture content. The unthreshed grain percentage was 0.66 % at 3.25 km/hr at 20 % level moisture content. The total grain loss was 1.7 % at 4.05 km/hr forward speed at 20 % moisture content.
Key words: Thresher, multi crop, threshing capacity, threshing efficiency, breakage
