After introducing the first models as a versatile remedy for storm cleanup late in 2017, Gradall is back with an updated version of its Discovery Series excavator lineup.

While the previous generation models were built atop the Freightliner M2, the new models are now perched atop Freightliner’s M3 truck chassis. With a full tilting, telescoping boom and easy travel between jobsites, Gradall is calling these new machines the industry’s first “crossover excavators.”

Gradall says the machines deliver “more dig for the dollar,” by being capable of doing the work of “several different machines.” Thanks to a range of quick-change attachments and its triangular boom that tilts 220 degrees, the company says Discovery excavators can perform ditching, grading, replacing culverts, landscaping, mowing, vegetation control and street and sidewalk repairs.

The company says Discovery Series excavators remain productive even in tight environments like under bridges and inside tunnels, while the Freightliner frame and suspension provide stability for high productivity when pulling curbs or sidewalks.

Maximum dig depth is 13 feet, 6 inches. Max boom reach is 24 feet, 11 inches.

The Freightliner M3 cab has room for two and offers “best-in-class” visibility, Gradall says, with a sloped hood and a 2,500-square-inch windshield. A Cummins 6.7-liter engine powers the M3 and is paired with an automatic transmission.

Inside the excavator cab, Gradall says operators will find a quiet work environment with a “full view of the jobsite” and an adjustable seat. The machine’s joysticks allow for choosing between Gradall, Deere or SAE control patterns.

Discovery Series excavators will be available in two- and four-wheel drive configurations with pricing starting at $255,000. Contact your nearby Gradall dealer or visit for more information or to set up a demonstration.
