This bucket is designed with a patented recessed pin to provide maximum digging performance while keeping the versatility and convenience of a coupler. Tip radius is reduced and allows up to 10% improvement in breakout force when compared to a conventional pin-on Bucket and Coupler combination. Center-Lock Performance Buckets are available for 315-345 excavators, in General Duty, Heavy Duty and Severe Duty durabilities.

These buckets are designed for cleaning ditches, slop- ing, grading and other finish work. Their shallow depth and compact size make working in confined areas easier. Drainage holes allow liquid to empty so material dumps more easily. Ditch CleaningTilt Tilt Buckets feature a full 45° of tilt in each direction, powered by two double-acting cylinders. Ditch Cleaning and Tilt Buckets are available for 311-336 excavators.
