ABSTRACT:
A vibrating ripper having quadrilateral linkage. The linkage, equipped with a remote hydraulic control therefor for making running adjustments as afforded by a depth actuator cylinder during ripping and possibly, but not necessarily, as afforded by a pitch actuator cylinder which also can be provided, has a raised-carry position and a lowered-rip position in which it has a vibratory rocking action, and defines a pitch axis fixed in the linkage and shifting therewith during depth changes. Strategic upper level placement of an elastic strut connection which is provided, and diagonal placement of the lift or depth cylinder connection to the draft frame or to the ripper beam and shank assembly, locate the pitch axis at the node of the rocking assembly as it vibrates.
