AM18 Backhoe Mill Attachment

When connected to the backhoe remote hydraulic system, the Maddock AM18 Backhoe Mill becomes a tool for asphalt or concrete cuts and grinding of shelf rock or outcroppings in construction work. The Depth Gauge allows the operator to pre-select the cutting depth from flush to max. depth in 1/2″ increments.

The Backhoe Mill allows for a maximum cutting depth of 9 inches (12” with depth gauge delete), and is unmatched in cutting depth capabilities for asphalt milling attachments. When compared to skid-steer milling attachments the Backhoe Mill offers several advantages; sufficient down force to penetrate while maintaining depth control, superior operator visibility of work area and cutter, cleaner operator environment, larger working envelope, and cleaner engine environment. The Backhoe Mill is one of the few milling attachments that can cut above grade, useful when cutting on steep slopes.

**** Please Note **** Although the Maddock AM18 can cut a maximum depth of up to 9” it is recommended that multiple passes be done in order to efficiently clear materiel.

**** Please Note**** A maximum of 12” cutting depth can be achieved with a depth gauge delete.
