发明名称 Ripper for attachment to tractor
摘要 Attachment for a tractor to do ripping, having parallelogram linkages which support a ripper shank assembly for movement between a raised-carry position and a lowered-rip position. The linkages each have an extensible side consisting of an hydraulic cylinder which allows the shank assembly to be pitched about a transverse horizontal beam axis when located in either of the just mentioned positions or any positions therebetween. A further hydraulic cylinder is connected on one end thereof to a mounting tower by a removable pin for attachment to the tractor and on the other end thereof to a clevis pivot in coaxial alignment with the horizontal beam pitch axis. This further hydraulic cylinder functions as a depth actuator.
