Four models are added to Deere K Series of crawler dozers: 550K, 650K, 700K and 750K. John Deere PowerTech Tier 4-Interim diesels provide more horsepower than the J Series predecessors: 85 horspower in the 550K, 101 in the 650K, 125 in the 700K, and 155-165 horsepower in the 750K at 1,800 rpm. Engines maintain oil flow to machine systems to enable operation on slopes up to 45 degrees. A hydraulically driven cool-on-demand fan operates only as needed. A reversing feature is standard on the 750K and optional on the others. The 700K and 750K have the company’s exclusive V-Cool package that isolates coolers from dust and engine heat. It is positioned behind the heavy-duty grille and fan, making the coolers less vulnerable.
The D65Pxi-18 crawler dozer incorporates Komatsu’s intelligent machine control technology and a Tier 4-Final, 217-horsepower SAS6D114E-6 engine.
Komatsu’s 264-horsepower D85-18 crawler dozer, aimed at large construction operations and small mining customers, features a Komatsu SAA6D125E-7 variable geometry, turbocharged and aftercooled Tier 4-Final-certified engine that the company says burns up to 5 percent less fuel.
Three E Series articulated dump trucks have been updated with Tier 4-Final John Deere PowerTech diesels.
The 210L and 210L EP tractor loaders meet Tier 4-Final standards with 93-horsepower PowerTech Plus and 70-horsepower PowerTech E engines, respectively.
