发明名称 TREE CROSS-CUTTING BLADE ASSEMBLY
摘要 Tree cross-cutting blade assembly are each trough-shaped with outwardly inclining sides leading from a bottom of the trough which slopes downward and terminates as the blade cutting edges. The blades are mounted for movement towards one another along paths which are substantially straight when viewed in a horizontal direction so that a portion of the tree between the troughs is compressed to alleviate splitting while it is being cut.
