JOHN DEERE 844K III AGGREGATE HANDLER WHEEL LOADER

Technical Description

The John Deere 844K III Aggregate Handler is a heavy-duty wheel loader engineered for high productivity in aggregate handling and material moving. It features a powerful 13.5-liter Deere PowerTech 6135 engine delivering 401 hp (299 kW) and 1,870 Nm torque at 1,000 rpm, compliant with Tier 4 Final emissions standards. The loader is equipped with a five-speed powershift transmission with torque-converter lockup in gears two through five, enhancing acceleration, transport speeds, cycle times, and fuel efficiency. Its rated bucket capacity is 9.3 cubic yards (7 m³), with enhanced performance buckets incorporating integrated narrow spill guards and curved side cutters for improved load retention and visibility. The machine's design includes increased tilt cylinder size, higher hydraulic pressure, and optimized counterweighting to manage larger buckets and heavier loads with stability and full-turn tipping capacity. The 844K III Aggregate Handler boasts an operational weight of 80,052 lbs (36,311 kg) and a dump clearance at max raise of 10.11 feet (3 meters), enabling efficient two-pass loading of up to 24 short tons of processed, non-heaping aggregate into on-road trucks, cutting loading time by 30% compared to conventional loaders. It features Deere’s Quad-Cool system with a reversing fan for easy cooler cleanout, integrated tire pressure and temperature monitoring accessible via cab display and JDLink telematics, and a low center of gravity for enhanced stability. The robust design supports heavy-duty applications with improved fuel consumption and enhanced operator visibility, making it suitable for challenging aggregate handling environments.
