Abstract: A mounting assembly of a gauge wheel for an implement, such as an agricultural crop harvesting header, the mounting assembly including a king pin member rotatably mounted in a king pin bushing housing and having a wheel spindle projecting substantially horizontally from one side of a king pin shaft for rotatably mounting the gauge wheel. The rotational axis of the king pin shaft is tilted rearwardly and upwardly relative to the vertical and sideways and upwardly relative to the vertical in a direction opposite to the side of the projecting wheel spindle. Accordingly, when the gauge wheel enters a caster turn in a direction corresponding to the direction of projection of the wheel spindle the axis of the wheel spindle swings from a substantially transverse direction in relation to the straight ahead travel direction towards a rearwardly and downwardly inclined orientation.

Abstract: An active rotary harrow is towed with its longitudinal horizontal axis at an acute angle relative to a line perpendicular to the direction of travel. A plurality of unitary tines are mounted by bolts or rivets on mounting plates which are secured to a shaft aligned along the horizontal axis. Each tine is made from spring steel which is flattened on one end, the flattened portion being mounted directly on the mounting plate by two or more fasteners. The tines are curved such that the outer end of the tine, being rounded in shape, is directed towards the trailing end of the harrow when in operation. The tines, and to a lesser extent, the mounting plates, are resilient in nature and can be deflected towards the trailing end of the harrow, when obstacles such as rocks are encountered. The tines are also capable of some pivotal deflection, to a lesser extent.

Abstract: A guide and control device for an agricultural machine subjected in operation to a high lateral thrust in relation to its direction of traction, such as a disk-type stubble-plough includes a guide and control system having at the front, a set of freely oscillating twin wheels the orientation of which for a change from a road-travel position to a soil-working position is controlled from a bar for coupling to a tractor. A carrying wheel is arranged in a central part of the frame, and at the rear thereof are arranged freely oscillating twin carrying wheels and furrow wheels controllable simultaneously from their road-travel position to their working position, and vice versa. The multiplicity of carrying wheels guarantees that sufficient grip with the soil is maintained permanently, thus preventing any lateral slip of the machine during passage over a movable obstacle, this also being assisted by the automatic orientation of the twin wheels by means of their freely oscillating mounting.

Abstract: This invention relates to a heavy duty commercial lawn edger apparatus utilized to achieve a new and novel contoured edge cut between adjacent portions of a grass area and a concrete or curb area. The lawn edger apparatus includes a main support base assembly directed by a main handle and control assembly and having a main power assembly mounted thereon. The main power assembly is connectable through a belt and pulley drive assembly to selectively drive a main edging and cleaner assembly. The main edging and cleaner assembly includes a heavy duty blade assembly; a main brush assembly mounted adjacent the main blade assembly for surface cleansing purposes; and an adaptor cutter assembly releasably connected to the main blade assembly to achieve unique shapes in the contoured edge cut. The main blade assembly includes a thick main blade member having spaced cut out sections to achieve a novel cutting feature of this invention.

Abstract: A locking structure for a disk tiller or the like which simply and quickly secures the rear furrow wheel in either an operational or transport position. An elongated link is pivotally connected to the disk tiller frame. The link is received in a guide structure carried by the disk tiller frame and is reciprocably shifted to vary the angular position of the rear furrow wheel support arm relative to the disk tiller frame. A pair of horizontally spaced latching pins are carried adjacent the guide, are biased towards the link and are selectively and alternatively engageable with abutment surfaces on the link to secure it in either of two spaced reciprocable positions.
