Gradall’s Discovery Series excavators are the industry’s first crossover excavators. They combine the benefits of the excavator’s full tilting, telescoping boom with rhe ease of travel of a Freightliner M3 truck chassis.
Operators can drive it to one or more job sites in a single day with Cummins 6.7L engine, an automatic transmission, and a big wheel cut for curb-to-curb maneuverability.
Once on the job, the Discovery Series model does the work of several different machines — ditching, grading, replacing culverts, landscaping, mowing, vegetation control, and street and sidewalk repairs, thanks to a range of quick-change attachments and a strong triangular boom that tilts 220 degrees.
The Freightliner cab accommodates two people and offers best-in-class visibility with a sloped hood, low profile dash, and a 2,500-square-inch windshield.
In the cab, the operator can raise, lower, rotate, or swing the boom either left or right using joysticks, selecting either the Gradall, Deere, or SAE patterns. The entire boom tilts 220 degrees, enabling operators to properly position attachments for tree trimming, sloping, and material picking and placement.
Maximum dig depth is about 13 feet, 6 inches, while maximum boom reach is about 24 feet, 11 inches.
Even under bridges and in tunnels, the excavator’s boom telescopes into position, remaining fully visible through the entire dig cycle. And because of the stability and strength added to the lightweight Freightliner frame and suspension, the Discovery Series excavator continues to be stable during high productivity excavation or when pulling curbs and sidewalks.
Available in two-wheel-drive and four-wheel-drive configurations, Discovery Series excavator pricing starts at about $255,000.
