Abstract

|
The study aimed at development of a riding-type mulberry harvester for mechanical harvest. A riding-type mulberry harvester has been developed to harvest on sloped land with a higher effeciency. It has been implemented over a period of 2 years from 1996 to 1997. The result is as follows. It moves on carterpillar with a level adjusting system. It reduced only from 14.6 hrs to 0.9 hrs/10a for cutting in a range of 25 to 80 cm high and possibly used for both spring and autumn. It reduced only the labor requirements of mulberry harvesting by 94 percent, as compared to that of the manual harvest. All related processes, cutting, binding and loading are simultaneously done by this harvester and totally it can reduce 96percent of the labor requirements, as compared to 20.4 hrs/10a of the manual harvest. The machine compared to improved mulberry harvest efficiency with 11.1a per hour by about 23times as compared to 0.49a per hour manpower. Cost analysis indicated that the riding-type mulberry Harvester saved overall cost by 66 percent from 980,000 won per ha manpower to 330,000 won per ha.
