John Deere added four models to the K-Series crawler dozer line, providing producers an emissions-certified machine that affords higher productivity, increased uptime and lower daily operating costs in earth moving and grading applications. The 550K, 650K, 700K and 750K crawler dozers build off the 850K that launched in 2011. A John Deere PowerTech 6.8L (700K, 750K) or 4.5L (550K, 650K) IT4 diesel engine provides an increase in horsepower from the previous J-Series, along with increases in overall tractor weight, resulting in more productive machines. The horsepower ranges include: 85 hp (550K), 101 hp (650K), 125 hp (700K), and 155-165 hp (750K) at 1,800 RPM. The John Deere IT4 engine also offers operation on slopes up to 45 degrees while maintaining adequate oil flow to machine systems. A hydraulically driven cool-on-demand fan operates only as needed, decreases cab and bystander noise levels and cuts fuel consumption. A reversing feature is standard for the 750K and optional for the 550K, 650K and 700K to blow out debris.
