Dual-purpose, four-season machine

Use the M7 as a ballast regulator during spring, summer, and fall. Then simply swap out several components to convert it into a snow-fighting machine in the winter.

Three wing types available for all ballast-sculpting needs

Three available wing types - fixed, rotational, and articulating rotational- allow for precise ballast sculpting and profiling, while handling varying grades of ballast. In addition, the broom is easily adjusted for specific height and tilt requirements.

Handle multiple snow-removal situations

Need to remove snow on your main lines as well as in your yard? The M7 is designed to handle all your snow removal needs:

  • Heavy-duty snow wings with 16.5 foot reach on each side
  • Positionable three-stage snow auger and blower
  • Multi-position snowplow for V-configuration or left/right snow placement

Lower cost of ownership

Since you only need one machine for ballast regulation and snow removal, you save on initial acquisition costs, maintenance costs, and even storage costs - lowering your overall total cost of ownership.

In addition, the M7 uses many of the same components as other Nordco machines, so you can stock fewer maintenance parts.
