Innovative Dozer Design
Komatsu’s super slant nose dozer design is revolutionary. Moving the coolers and cooling fan to the rear of the machine and moving the operator forward accomplished two important things; 1.) The operator has an unobstructed view to the top of his blade, and 2.) balance is improved to the point where it becomes an incredible grading tractor. In 2008, when the first model of this design was introduced, it entered Business Week’s International Design Competition. It was awarded second place behind the Apple iPhone. Not bad company. Take the design a step further and marry it up with a blade control system, and you have a very accurate, high-speed grading system. See the D37, D39, D51, and D61 dozers for more information.
Hydrostatic Drive and Steering
Hydrostatic drive and steering in small and mid-size bulldozers give the operator great control over his machine’s movement and speed. With palm control, the operator has very smooth and precise directional control. Twenty-one speeds are available, or if preferred, the operator can select one of three quick-change settings. All the technology that goes into hydrostatic drive and steering is designed to do one thing: make the operator more productive. See the D37, D39, D51, and D61 dozers for more information.
Small Komatsu wheel loaders (167 hp. and smaller) utilize a hydrostatic transmission instead of a geared transmission and torque converter. The hydrostatic transmission has the advantages of being lighter, having fewer wear components, having auto shifting, a quick response time, excellent tractive effort when digging in the pile and climbing/stockpiling, variable traction control, and dynamic braking.
