What Is a Pat Blade on a Dozer?
Power-Angle-Tilt (PAT) bulldozer blades provide blade angling and tilting from the driver’s seat. These type blades are primarily used in grading, back-filling, land-clearing and spreading operations.
Operation
PAT blades are powered to lift, angle and tilt in virtually every desired direction. The shape of an individual blade determines its best working purpose, with the blade-to-ground angle of intersection directly related to the blade curvature. Most PAT blades operate by use of a joystick located within the dozer cab.
Types
Some dozers come equipped with 8-way blades, though the 4- and 6-way are most common. 6-way blades are truly Power-Angle-Tilt capable while 4-way blades usually lack angling properties. The additional movement potential of the 6-way blade, including rotation and tilting, make it preferable for spreading dirt and clearing brush.
Functions
PAT blades convert dozers into powerful dirt-moving machines. Primary functions of a PAT blade-equipped dozer include ground leveling, scraping, grading and swale cutting.
