Abstract: A self-propelled lawn aerating machine includes a plurality of generally vertically reciprocally movable tines operated by a cam shaft for removing plugs of soil from a lawn. The tines are spring biased upwardly and in forward direction toward a bumper board located forward of the tines. When withdrawn from the lawn the tines strike the bumper board with sufficient force to break the soil plugs and cause the resulting loose soil to be scattered over the surface of the lawn as the machine moves along an aerating path. The bumper board has a raised position wherein it supports the tines in an idling position above the surface of the ground while the machine is moved across walkways, driveway, and the like.

Abstract: A sod harvesting machine travels forwardly along a path of travel and has a sod cutting head pivotally connected to a fixed rear frame by a horizontal front pivot shaft having its axis aligned along the path of travel and located close to the ground, and by a pair of rear pivots. The rear pivots are formed by a pair of curved tracks and rollers at the rear of the cutting head, well above the ground, allowing the front of a conveyor to be brought near the ground and close behind the sod cutting knife. The curved tracks have a common center of curvature located on the axis of the front pivot shaft so that they have the same effect as a horizontal rear pivot shaft located close to the ground and aligned with the front pivot shaft.

Abstract: Improvements in flexibility for wide swath agricultural implements having hinged wing frame sections to enable the implement to be folded compactly for transport and also to better follow ground contours are provided by dividing at least one of the sections into side-by-side subsections which are pivotally interconnected for relative movement about a transverse axis. Thus, relative flexing between adjacent frame portions can take place about hinge axes parallel to travel direction while relative flexing between adjacent wing sections of the frame can take place about transverse axes. Preferably the pivotal interconnections are located to divide the frame into portions of equal width and the pivotal interconnections are reinforced by link means which connect the adjacent portions to resist bending movements about a vertical axis at the interconnection while still permitting the hinged sections to be folded.
