Gradall D174

The Gradall D174 is a highway-speed wheeled excavator built on a 4x4 Freightliner chassis and powered by a Cummins ISB 6.7-liter engine producing 300 HP. Engineered through a joint Gradall-Freightliner collaboration, the D174 combines over-the-road travel at 60 mph with the signature Gradall full-tilting, telescoping boom that tilts 220 degrees and telescopes to 27 feet 7 inches. With a maximum digging depth of 13 feet and a 5,490-lb lift capacity, it handles ditching, ditch cleaning, drainage maintenance, mowing with rotary or flail attachments, and pavement repair — making it a high-value single-machine solution for municipalities and specialty contractors.
