NewRoadProducts JOHN DEERE Four new K-Series crawler dozers John Deere is adding four models to the K-Series crawler dozer line. The 550K, 650K, 700K and 750K crawler dozers build off 850K that launched in 2011. A John Deere PowerTech 6.8-L (700K, 750K) or 4.5-L (550K, 650K) Tier 4 Interim diesel engine provides an increase in horsepower from the previous J-Series, along with increases in overall tractor weight. The horsepower ranges include: 85 horsepower (550K), 101 horsepower (650K), 125 horsepower (700K), and 155 to 165 horse- power (750K) at 1,800 rpm. The John Deere Tier 4 Interim engine also offers op- eration on slopes up to 45 degrees while maintaining adequate oil flow to machine systems. A reversing feature is standard for the 750K and optional for the 550K, 650K and 700K to blow out debris.

This feature allows oper- ators to use the auxiliary drive for hydraulics and other resources with the simple flip of a switch. The P125WJDU is ideal for paint striping applications. The air compressor has a free-air delivery of 125 cfm, a rated operating pressure of 100 psig and is powered by a Tier 4 Interim-compliant John Deere 49-horsepower diesel engine.

The BW138AD-5 delivers a maximum centrifugal force of 10,800 pounds. With a working width of 54.3 inches, the roller includes larger 35.4-inch diameter drums and provides dual-vibration frequencies of 3,480 or 2,820 vpm. The roller's bolt-on oscillating and articulating joint improves maneuverability by allowing the rear drum to follow the same path as the front drum while turning. Write 31 on reader card JCB Improved digging geometry JCB offers eight new small-platform skid-steer and compact track loader models: the 135, 155, 175, 190 and 205 skid steers and the 150T, 190T and 205T compact track loaders. The 135, 155 and 150T machines feature radial lift, which offers improved digging geometry for heavy loading applications. Because they contain fewer pins and bushings, radial lift machines perform well in high-cycle applications such as waste, recycling and demolition. The 175, 190, 205, 190T and 205T models offer vertical lift, which provides maximum reach at full height. Write 32 on reader card 39c May 2012 Better Roads 39b May 2012 Better Roads
