Purpose-Built Cat Attachments

Cat blades are resilient, durable and designed with excellent dozing and rolling characteristics.

Capacities and widths are set to achieve increased productivity.
Spreading design allows for spreading of cover material, as well as dozing of heavier loads.

The straight blade (7.9 m3/10.3 yd3) is designed for production dozing in stockpile material and general earthmoving. The universal blade (11.1 m3/14.7 yd3) is designed to move large loads over long distances in mining applications.

The characteristics of the straight and universal blades are combined into the semi-universal blade (10.1 m3/13.3 yd3). It provides increased capacity with the addition of short wings which include only the dozer end bits without sacrificing spreading characteristics of straight blades.

The coal blade (22.2 m3/29 yd3) is designed for precise and productive dozing while helping to retain load control with increased capacity for lighter materials. Wing angles help retain the load while dozing. This blade is available from Cat Work Tool and Services (CWTS).

The straight, semi-universal and universal blades consists of the blade, push arms, hydraulic lift, tip and tilt cylinders, trunnion mounting, stabilizer and hydraulic line guards. See your Cat dealer for blade options such as coal and wood scoop from CWTS and Custom Products.
