Gradall has updated its XL3100 IV wheeled excavator with a six-speed AutoDrive Allison automatic transmission and an undercarriage that allows the machine to be driven at speeds up to 60 mph. Operators can reposition the machine from the upper cab. The 218-horsepower Tier 4-I Mercedes engine also powers the upperstructure boom, including swing motions. Advanced hydraulic system has pressure-compensated, load-sensing valves with reliefs on all circuits.
