Premier Attachments offers two types of Backhoe Earth Auger Drives: The Heavy Duty High Flow earth auger drives are built for the toughest drilling conditions and designed to work on machinery with hydraulic flows between 25 gpm to 60 gpm with torque output ranging from 3,624 ft. lbs. to 35,297 ft. lbs.
The 2-Speed High Flow earth auger drives are built for variable conditions that require a balance between torque and speed to be maximized throughout the project. The auger drive shifts-on-demand when high torque/low rpm conditions exist and returns to low torque/high rpm when digging eases up.
The chart below lists of most popular Backhoe Heavy Duty High Flow and 2 Speed High Flow models. For a complete list of mounts, augers, adapters, extensions, collars, parts and accessories, please see our Premier Attachments Catalog.
