Carrying the Load
John Deere’s 844K wheel loader features a bucket range from 7.25 to 8.1 cubic yards with a 47,860-pound breakout force. An enhanced multifunction monitor provides easy pushbutton access to machine information and control. A low center of gravity and optimized fore and aft balance delivers stability and full-turn 44,713-pound tipping load capacity. The powershift torque-converter transmission uses smart-shift technology to continuously evaluate speed and load conditions. Two control options, the single-lever joystick or two-lever fingertip pilot-operated hydraulic controls, include Deere’s Quick Shift feature which allows pushbutton gear changes.
Power Shift transmission
Doosan Infracore’s 6.3-cubic-yard DL500 has a 335-horsepower engine and Power Shift transmission. The loader has more power and a larger cab than its predecessor, according to the company, and improvements to the power train are said to have increased fuel efficiency. In addition to new comfort features, such as a multi-adjustable air-suspension seat, the DL500 has larger front pins and all grease points for pins and bushings are accessible from the ground.
Turbocharged “Extra” model
Dressta says its 560E Extra model features a new Tier 3 turbocharged 427-horsepower engine, joystick boom and bucket controls, hydrostatic steering, and a high visibility cab. The 7-cubic-yard wheel loader has a three-speed, full powershift, countershaft transmission and 92,549-pound operating weight. The machine uses Z-bar linkage for maximum breakout force, and a single bucket cylinder to reduce weight in front of the machine and enhance payload capacity. Oil change intervals have been increased to 500 hours.
