![]() ![]() In this size class customers are asking for machines that are simple to operate with technology to enable operators to stay comfortable and productive." Andrew Earing, senior product manager with Komatsu, agrees, and says that when it comes to features, machine control is seeing steady growth as customers seek more efficient solutions for their work that can increase their profitability. "When we think about challenges our customers face, it's common to hear about the shortage of skilled operators. Machine control and other integrated technologies are going to be a big part of the future." Matt Goedert, solutions marketing manager, roadbuilding, with John Deere Construction & Forestry, agrees that technology is part of the solution as the workforce changes. "Operators need a machine that they can get in and learn fast. The key trends that are driving innovation in the small dozer category are primarily centred around operator experience and efficiency including comfortable cabs, easy-to-use controls and operation settings that maximize production. According to Jeremy Dulak, product and marketing manager, dozers, with CASE Construction Equipment, the small dozer market is the largest size class in the industry and continues to grow. Our panel of industry experts highlights how going smaller, where possible, can yield great results for many applications, such as road widening, brush clearing, and residential and general construction. Like their larger counterparts, smaller-size dozers under 25,000 pounds deliver considerable pushing power and can be outfitted with the latest in machine control technology, but they have some advantages: easier transportation ability to fit into narrower areas, such as the lane of a road and lower operating costs. 550K: 85 hp PowerTech 4.5L base weight 19,290–20,272 lbs.As working space has become smaller and efficiency needs have become greater on a range of construction sites, deploying powerful but smaller equipment is a must and can maximize efficiency in a range of jobs. ![]() K-Series dozers constantly monitor their own transmission temperature, and the monitor has a special warning light to alert operators when the transmission is too cold or too hot for normal operation. The display in the cab provides real time values for every temperature, pressure, and speed sensor on the machine. The 700K and 750K come equipped with John Deere’s exclusive V-Cool package, which isolates coolers from dust and engine heat to increase cooling efficiency and durability. ![]() The diesel particulate filters (DPF) are cleaned automatically during routine operation. A hydraulically driven cool-on-demand fan operates only as needed, decreases noise levels, and cuts fuel consumption.Ī fan-reversing feature to blow debris from the coolers is standard for the 750K and optional for the 550K, 650K, and 700K. The K-Series uses cooled exhaust-gas recirculation (EGR) with exhaust filters to meet 2012 EPA emissions regulations. With increases in overall weight for all, the new hydrostatic-drive tractors promise improved productivity. John Deere has upgraded its 550K, 650K, 700K and 750K crawler dozers to the new K Series with new, more powerful PowerTech engines across the line that satisfy EPA Tier 4 Interim emissions requirements. ![]()
