The 4JRA-160 is a user-documented Hongyou sweet potato vine crusher for harvest preparation. The 1,600 mm working width, three-point suspension and specified blade set support a mechanical foliage-management step before digging and collection operations.
Vine management is not a substitute for maturity management. The purpose is to reduce foliage obstruction, clarify the row path and prepare the field for the subsequent lifting operation. Excessive disturbance can expose or damage roots, so ground speed, cutting height and the timing before harvest should be set for the local crop and weather conditions.
