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.
John Deere's new E-Series skid steer and CTL line includes five skid steers and four compact track loaders, each with Tier 4-Interim or Tier 4-Final engines and other improvements.
John Deere's 644K Hybrid wheel loader utilizes two sources of energy, diesel and electric, capturing regenerated energy as it’s being created and using the energy to power the machine.
