dc.descriptionAbstract: To improve the digging capability of small excavators and backhoes in hard and frozen ground, a bucket of special design was selected from among a variety of attachments. This bucket cuts and rips the frozen ground, as lip teeth and a set of staggered teeth attached to the back of the bucket move through an arc during bucket rotation. Digging observations were made using a small mini-excavator and an Army tractor (SEE) with a rear-mounted backhoe. Frozen ground was excavated at several sites under impossible conditions for a conventional bucket. A large variation in excavation rates (3 to 30 yd^3/hr [2.3 to 23 m^3/hr]) was observed, depending on material type, frost thickness, sharpness of the cutters and operator experience.-
