MARKET WATCH

摘要

Models 550K, 650K, and 700K have been added to the K Series crawler dozer lineup and updated with Tier 4-Final engines: a 92-horsepower PowerTech 4.5L in the 550K, 104-horsepower PowerTech 4.5L in the 650K, and a 130-horsepower PowerTech 6.8L in the 700K. DPF cleaning occurs automatically, and the machine requires DEF. EcoMode optimizes fuel economy and can save up to 20 percent in fuel, according to Deere. A pushbutton throttle replaces the rotary dial to control rpm. Hydrostatic transmissions have updated electronic control systems, and motors were upgraded from a two-speed design to variable displacement. A blade shake feature causes the blade to shake in a "quick, repeated motion" to clear material from the blade.
