Three updated models join John Deere’s K-Series four-wheel drive wheel loader lineup: the 744K-II, 824K-II and 844K-II.
The EPA Tier 4 Final/EU Stage IV diesel engines meet emission regulations without sacrificing power or torque. The 744K-II (303 hp), 824K-II (333 hp) and 844K-II (377 hp) are built on the Interim Tier 4/Stage IIIB solution. The technology was designed to be simple, fluid efficient, fully integrated and fully supported, employing field-proven cooled exhaust gas recirculation (EGR), easy-to-maintain high-uptime exhaust filters and selective catalytic reduction (SCR).
The K-Series-II loaders come equipped with larger, higher-capacity Teammate V Axles (744K-II and 824K-II) with standard cooling and filtration, and on-the-fly engageable front differential lock, giving operators heavy-duty traction for the most demanding terrain.
For added protection, axle oil is filtered by continuously cleaning wear particle and debris out of the oil.
Together, this system provides increased axle reliability and longevity. Brake reactors and automatic self-adjustors were added to eliminate brake drag and to maintain a constant brake running clearance with better compliance and less heat.
