Abstract: A grinding system including a pilot bit and a base having teeth extending from the base. The pilot may have a tapered cross-section, threads to control the rate at which it engages an object and a flute to facilitate the removal of material of an object. A method of using the device may include allowing the bit and the base to work together in a manner that the portions of the system engage an object at a similar rate.

Abstract: An hydraulically powered implement attachment for a powered machine is disclosed. The implement attachment comprises a frame member adapted for attachment to at least one movable arm of the powered machine. A reversible drive hydraulic motor member is mounted to the frame member. The hydraulic motor member includes a drive shaft extending therefrom and a pair of hydraulic power lines adapted for attachment to the powered machine. A power shaft is rotatably mounted to the frame member and operatively connected at a first end to the drive shaft of the hydraulic motor member. A rotationally operative implement member is connected to a second end of the power shaft. An operator of the powered machine actuates the rotationally operative implement member through rotation of the power shaft by the reversible drive hydraulic motor. Preferably the implement attachment member is a conical wood splitter member and the powered machine is a skid steer.
