RG72 RotoGrader

Asphalt Milling Attachment for Motor Graders

 

MaddockUtubeHor

Series I
This multi-purpose, self-powered milling attachment is designed to bolt to a motor grader moldboard (blade) assembly without any modifications to the grader. The drum is powered by a 6-cylinder, turbo-diesel engine rated at 200 horsepower. Optional engine ratings area available. The diesel power unit is designed to mount either to a front scarifier attachment, front lift group, fixed, or on the rear of the grader.

Series II
The cutter drum assembly on this model replaces the moldboard instead of mounting onto the moldboard. This design allows cutting outside the motor grader tires on either side without extending the moldboard into the adjacent lane. Both the Series I and Series II designs are available with various engine and cutter drum configurations to fit the application.

Operator Controls
A joystick control provides the operator with control of the speed of the cutter drum. Engage/Disengage and Engine Throttle are also controlled from the Operator Control Station, provided with the attachment.

Utility
Why tie up a loader, which is required when using the Asphalt Zipper or RoadHog, when you can mill asphalt with precision and stability with the RotoGrader Series II attachment.
