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.
Liebherr has introduced two Tier 4-Final crawler dozers, the PR 746 Litronic and PR 756 Litronic, joining the PR 736 introduced at Bauma last year.
Redesigned with a Cat C18 ACERT Tier 4-Final diesel, Cat D9T dozer has 436 horsepower at 1,800 rpm.
Eight-foot-tall 204K and 304K wheel loaders are new models in the Deere lineup, designed for lower-clearance applications.
Models 50G and 60G compact excavators meet Tier 4-Final standards with aftertreatment on their 36- and 53-horsepower engines, respectively.
