Abstract:
A sweeper mechanism adapted for directing grain in a circular grain tank to a central location adjacent a center of said tank, said sweeper mechanism comprising:a) an auger extending outwardly from said central location, said auger being adapted for rotation for directing grain within said grain tank toward said central location, said auger also being adapted to swing on a radius about said central location;b) a frame which supports said auger;c) a traction member coupled with the frame radially outwardly from the central opening, said traction member being adapted to engage the floor of the grain tank for driving the frame and auger about said central location;d) a power source operatively coupled with the auger for transmitting rotational power to the auger; ande) said traction member is operatively coupled with the auger for receiving rotational power from the auger;f) a hydraulic pump operatively driven by an end portion of the auger opposite the central location, said hydraulic pump being operatively coupled with a hydraulic motor for driving said hydraulic motor, said hydraulic motor operatively coupled with the traction member for driving said traction member.
