Genesis Attachments created the Genesis Rail Breaker that features an innovative four-blade design that reduces jaw wear and maintenance.

The GRB 30 features cutting blades on each side of the upper and lower jaws, minimizing parent material wear, extending jaw life and reducing the need for build-up.


A deeper jaw design provides increased bearing life and reduces pivot stress by keeping the cutting area in the center of the blades, away from the throat, and the large-bore cylinder produces more power for improved cutting.
