The Gradall XL 4100 IV hydraulic excavator features a new AutoDrive system that uses an automatic transmission—a six-speed Allison with push-button controls in the undercarriage truck cab. In addition to the undercarriage transmission, Gradall's AutoDrive system integrates a new transfer case, which is the heart of a new remote-drive design that enables operators in the upper cab to reposition the machine around jobsites or over the length of a roadside ditch. Models are available with either 6 x 4 or 6 x 6 drivetrain configurations. The XL 4100 IV also incorporates a new 245-horsepower Tier 4 Interim Mercedes engine and a pressure-compensated, load-sensing hydraulic system with relief valves in all circuits. Other distinguishing features for the new XL 4100 IV, says Gradall, include high-visibility LED lighting, a compact tail swing that allows the machine to work on roadside jobs without obstructing traffic, and a new high-visibility yellow paint scheme with red and black accents.
