ABSTRACT:
A steel insert apparatus for a backhoe bucket having an integral heating system to defrost construction equipment in cold weather is herein disclosed. The apparatus is intended for use on backhoes, front end loaders, bulldozers, and other similar equipment with a blade or a bucket. When required by cold weather, a conventional blade or bucket will have the apparatus inserted snuggly into the bucket. The insert contains a series of interconnected heating tubes along its inner surfaces. The heating tubes are connected to an input and output connection on each end which allows engine coolant to be circulated through the heating tubes by means of flexible hoses and fittings providing heat to the insert. Such a feature allows the construction equipment to be used in cold weather without being affected by ice or snow build-up.
