Bucket Works Like A Trencher

The Hi-Cap Multi-Ripper Bucket from Leading Edge Attachments is designed to fit any excavator or backhoe-loader above 11,000 pounds. The bucket works similarly to a trencher, but uses the backhoe's rolling action to rip. No two ripper teeth align with each other so that the maximum breakout force is applied sequentially to each tooth. The bucket scoops the ripped material to keep it from falling in the trench.
