Ripper assemblies are normally utilized for ripping hardened ground, rock, and so forth. Due to the type of ground being ripped, it is many times advantageous to selectively change the pitch angle of the ripper tip during the ripping operation. Furthermore, it is advantageous to have a push block associated with the ripper assembly in order to allow the second vehicle to provide an additional pushing force for ripping of the ground. When a ripper assembly incorporates an adjustable pitch control and has a push block, the visibility of the ripper tip by the operator is many times limited or totally lost. In this subject arrangement, a push block is integral with a frame assembly and a ripper carriage assembly is pivotally secured to the frame assembly. By the push block being integral with the frame assembly, the ripper carriage assembly is simple and compact allowing better visibility by the operator to the rear of the ripper assembly. Furthermore, a slight opening is defined in the frame assembly immediately in front has a clear visibility of the area around the ripper shank and/or the ripper tip when the ripper tip is not engaged in the ground. The better visibility to the rear of the ripper assembly is enhanced by having first and second pitch control cylinders universally secured to the ripper carriage assembly generally adjacent thereto. |
