Abstract: Front and rear frame sections are provided with the front section including central and opposite side rearwardly diverging front frame members including forward ends anchored relative to each other and a laterally spaced apart rear ends. The rear section includes central and opposite side rearwardly divergent rear frame members including laterally spaced apart forward ends and rear ends removably supported from central and opposite end portions of a transverse axle assembly having ground engageable support wheels journalled from its opposite ends outwardly of the rear ends of the rear frame members. A trailer hitch assembly is carried by a forward portion of the front frame section and the front and rear ends of the rear and front frame members are removably telescopingly engaged with each other.

Abstract: A mobile frame including a generally frusto-conical ground wheel journaled for rotation about a generally horizontal but inclined transverse axis with the lowermost slant height of the wheel disposed for surface-to-surface contact with the ground over which the frame is advanced. The minor and major diameter ends of the wheel are open and closed, respectively, and an upstanding rotary disk is journaled from the frame for rotation about an axis generally paralleling the axis of rotation of the wheel and with the disk disposed closely outwardly of and closing the rear lower quadrant portion of the open minor diameter on the end of the wheel. Stone deflecting structure is positioned outwardly of the minor diameter end of the wheel for deflecting windrowed stones thereinto and the interior of the wheel includes lift members for support of rocks therefrom and thereby operative to elevate rocks received into the open end of the wheel upon rotation of the latter.
