2053899 9116507 PCTABS00008 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 (52) is integral with a frame assembly (14) and a ripper carriage assembly (16) is pivotally secured to the frame assembly (14). By the push block (52) being integral with the frame assembly (14), the ripper carriage assembly (16) is simple and compact allowing better visibility by the operator to the rear of the ripper assembly (10). Furthermore, a sight opening (46) is defined in the frame assembly (14) immediately in front of the ripper carriage assembly (16) so that the operator has a clear visibility of the area around the ripper shank (70) and/or the ripper tip (72) when the ripper tip is not engaged in the ground. The better visibility to the rear of the ripper assembly (10) is enhanced by having first and second pitch control cylinders (98, 100) universally secured to the ripper carriage assembly (16) generally adjacent thereto.
