Grader Rippers

Motor Grader Rippers & Scarifiers

All grader rippers are produced using the highest quality processes and materials. Components are hardened to between 200 and 500 BHN. Welding is does with low hydrogen electrodes to provide the highest quality strength and no distortion. After fully testing all hydraulics the rippers are sandblasted and painted.

These attachments are used in applications ranging from conditioning soils and mixing materials to loosening hard material and to ripping asphalt. While motor graders are not designed to continuously rip hard material, they will do a good job if properly used. Minimize articulation while ripping to avoid side loading the ripper or shanks causing possible failures.

A front scarifier hooks to the front lift group and is normally used for light work. Since the lift group is used for raising and lowering, it is cost effective. Its disadvantages include less control of direction and cut depth when ripping, due to its location ahead of the steering wheels. This location also limits visibility to the scarifier teeth and material fracture.

Compared with a front scarifier, a midmount scarifier has better control of cut depth, improved visibility and ability to fracture harder material. Disadvantages are interference with blade positioning, interference with material flow along the moldboard in some applications, and problems working into corners and close to objects.

A rear ripper/scarifier allows maximum ripping capability by placing the ripper weight on the rear-drive tires. It can be used to rip into corners, along walls or close to an object. The ripper shanks are used for heavy ripping; the scarifier shanks are used for light work where maximum surface fracture is desired. Both sets of shanks can be stored on top of the bar when not in use.
