| Combine header loss comprises more than 50% of wheat harvesting losses. Therefore, decline in this part of the loss to the extent allowed amount is an important step in reducing of crop wastes. Combine header is a complex system in which several factors are involved in its work. And, if these factors can be adjusted and controlled to suit the working conditions, to a large extent of crop loss can be prevented during the harvest. In this study, reel index, cutting height of crop and horizontal and vertical distance of reel from cutter bar were selected as the effective factors in header loss. In response surface method, central composite design was used to modeling and finding optimal levels of mentioned factors. The results showed that power model... |

| An existing 1.5kW brush cutter was modified and evaluated with the view to adapt a low-cost rice harvesting machine. The modifications included replacing existing blade with circular saw blade, incorporating a guider and a driver to lay down the harvested crop in swath and attachment of a harness belt for easy and comfortable operation. The machine was evaluated keeping in view major influencing factors i.e., crop establishment (conventional transplanting, system of rice intensification (SRI), and mechanical transplanting), blade type (B1: 40 teeth, pitch 1.92 and B2: 80 teeth, pitch 0.96) and straw moisture content (38-42, 33-37 and 28-32%, w.b). The results showed that the height of cut was significantly affected (p<0.05) by the crop... |
