Objective
Labor saving harvesting Improvement in
handling during work Reducing workload

Concepts of Harvester
1. Labor saving of stalk-cutting,collection,
carrying outside the ridge
Self-propelled Harvester with one worker
2. Improvement in handling of stalk-cutting
housing
Use of sticks Development stick-loading unit
3. Increase efficiency transferring from harvester
Use of stalk carrier roller conveyor
