Komatsu GD555 Ripper Assembly

Murray Engineering’s service exchange components are purpose-built to help you minimise downtime and control maintenance spend — without cutting corners on quality. With fast access to critical parts and components rebuilt to exceed OEM standards, we’ll help keep your grader in the dirt and out of the workshop.

The Komatsu GD555 Grader ripper assembly is a rear-mounted attachment used to break up compacted ground or asphalt prior to grading. It increases the grader’s efficiency by preparing the surface for finer material spreading and leveling.
