The 744K-II, 824K-II, and 844K-II wheel loaders meet Tier 4-Final emissions standards. Horsepower ratings are 303, 333 and 377 horsepower, respectively. Loaders have larger, higher-capacity Teammate V axles with on-the-fly engageable front differential lock. 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. The hydraulic tank was moved underneath the steps to maintain rear visibility without growing the size of the rear hood. The loaders are Loadrite L2180 ready, which provides on-board payload data and is integrated into JDLink Ultimate for remote viewing and analysis.
