Dethatching apparatus with independently rotating sets of tines

摘要

An improved ground-driven dethatching apparatus having at least two sets of independently rotating sets of dethatching tines. Each tine set is positioned along an independently rotating tine shaft which is rotated by a separate drive linkage and ground-engaging wheel. This arrangement ensures adequate torque to rotate the shafts and uniform dethatching when changing directions. The dethatcher automatically adjusts tine height, for example, in response to obstructions or variations in ground conditions.
