Cat Grading and Trenching Buckets Work with Cat Tilt-Rotator System.

A new line of Cat® grading and trenching buckets is available for Cat track excavator models 311 to 323 and for wheel excavator models M314F to M322F. The new buckets, available in both pin-on and coupler configurations, are specifically designed for use with the Cat tilt-rotator to provide an efficient, productive, all Cat excavating system.

The new buckets are designed to be used primarily with the tilt-rotator system having S, CW, and CWs lower interfaces to ensure proper fit and performance. In addition, the buckets can be used on machines having standard S pin-on, CW, and CWs quick-coupler systems for increased utilization. The new buckets also feature optimal dump and curl angles for added material control, as well as optimal vertical-wall positioning for trenching or working against walls. The CW, CWs and S style buckets are manufactured with high-grade steel and high- abrasion-resistant steel in critical high-wear areas.

Grading buckets
The grading buckets are designed for precise grading applications and for digging in semi-compacted dirt, having a wide, straight base edge and incorporating a long, flat floor. The conical design of the back allows the bucket to work well with the tilt-rotator when excavating near obstructions, such as walls or concrete pillars.
