![]() ![]() The dashboard and the dozer’s nose are tapered in dramatically to ensure those good sight lines, regardless of the situation you’re in.” So our redesign included improving sight lines from the cab to the blade and the areas behind the blade. Ease of grading is a typical application. “We know contractors have a hard time getting good operators,” Schaefer says, “and good operators are looking for dozers that allow them to work better. Taking cues from the H-series dozer line included retaining the older dozers’ comfort levels and ease of operation. The two smaller dozers (650K and 750K) have the four-cylinder, turbocharged engine, while the 850K features the six-cylinder, turbocharged diesel. All K-series dozers are still powered by Case’s CDC diesel engines. Right off the bat, it was apparent that although Case designers have made radical powertrain changes to this new dozer line, they were also careful to preserve many popular features that Case customers have come to know and depend on. On a warm summer day, we met with Schaeferat Northern Michigan Equipment, based in Traverse City, to conduct a K-series walk-around and test run. ![]() Undercarriage design tweaks enhance PowerStat capabilities “In stumping and hard dozing applications, these machines will push hard with ample low-end torque.” “You can see this reflected in the drawbar pull of this machine,” Schaefer says. Pulling power is important in dozing applications, and Schaefer says Case engineers were determined to retain that feature with the new hydrostat-drive system. We can’t route all the hydraulic power to one track, but we can get a higher percentage of the power to a track.” So we’re still able to maintain the advantage we had with our PowerTurn technology. ![]() Also, when it comes to turning, you can put almost all of the power through one side. “That does several things: it lowers the operating system pressure while you’re doing much of the operation. “But with our PowerStat, we’ve sized our hydrostatic components much larger to take more of the available hydraulic power through one side,” Schaefer says. ![]()
