发明名称 High-lead yarder rake
摘要 A high-lead yarder rake is capable of clearing brush, timber, and other debris at a logging site when hauled just above the surface along a main line with a main line yarder. The rake has a generally rectangular frame having a top, a bottom, two sides, a vertical, central cross-member extending between the top and bottom, and a horizontal tine support extending between the sides. A plurality of tines are mounted on the tine support to extend downwardly to rest against the frame's bottom and to project downwardly from the bottom as teeth. Additional support members may be used to strengthen the tine support. A riser extension may be added above the top to further increase the volume which the rake may hold. A method for using the rake to clear a site is also disclosed.
