Features: ● Straight Bulldozers — adjustable tilt angle controls blade penetration. ● Variable cutting edge Power Angle and Tilt (VPAT) — blade is available on the D3K2, D4K2, D5K2, D6K2, D6N, and D6T. The blade can be mechan- ically tipped forward for improved penetration or back for more productivity and easier finish grading. ● Angling Bulldozers — 25° right/left angling; C-frame allows mounting other tools. ● Universal Bulldozers — 25° wings provide increased capacity, less spillage. ● Semi-Universal Bulldozers — combines penetration ability of straight blade with increased load capacity provided by short 25° wings. ● Wheel Dozer blades are offered in straight and univer- sal blade design with hydraulic pitch and tilt control. ● Box-section construction on blades adds rigidity and strength. ● Cutting edges are heat treated and reversible for extra life.
