Abstract: A particulate material spreader comprising a ground-contacting platform adapted for detachable connection to towing device which causes the platform to traverse the ground so as to engage at least in part the surface thereof subtended by the platform. Engagement is by one or more members supported by the platform transversely with respect to the transit path of the platform. Each member has at least one vertically resolvable surface irrespective of the attitude of the platform. The connection is such that a pre-set angle of the platform with respect to a horizontal plane is maintained during transit whereby the members gouge relatively high areas of engaged ground and fill relatively low areas thereof with spoil from those high areas. The platform is attached to the towing device by a selectively detachable three-point linkage which may be mounted on one end or the other of the platform.

Abstract: A plurality of ground working sections such as cultivator sections, are flexibly connected together and operatively connected to a hitch pole assembly. Each section is supported upon a pair of castor wheels mounted on a fore and aft beam pivotally connected to the front and rear of the frame members. The sweeps or cultivators move in an arc via hydraulic or mechanically operated rock shafts and the depth control is by means of controlling the pivotal movement of the fore and aft beams. This also permits the penetration angle of the sweep or cultivator to be preset and maintained. For transport, the draw pole is raised and the implement is towed by one end thereof with the castor wheels automatically aligning with the direction of travel thus eliminating folding or raising of sections and permitting practically any length of cultivator or ground working implements to be assembled.

Abstract: An implement has at least one group of soil working members arranged in a row that extends transverse to the direction of travel. The group of members is carried on an elongated frame portion that is connected to an overlying supporting structure by parallelogram linkages. Fore and aft ground wheels on corresponding arms interconnect the wheels to beams of the structure and the arms for the front wheels form part of further parallelogram structures. A hydraulic piston assembly bridges each rear arm to an upper arm link of a further parallelogram linkage so that the arms can be pivoted and the supporting structure together with the frame portion with soil working members, are raised to a transport position. The wheels can each be adjusted about a vertical axis to support the implement, in part, during operation or entirely during transport. Respective coupling members are attached to the front and the side of the implement for towing same in either position.

Abstract: A tractor implement attaching hitch mechanism of the three-point type that utilizes a hydraulic actuator for readily adjusting the attaching mechanism out of a vertical plane, whereby the remotely controlled latches may be activated for attaching the implement to the tractor.The hitch mechanism comprises a frame including a pair of depending legs interconnected by a horizontal support member. The support member and one of the legs include brackets which are connected to two draft links of the tractor, and the other leg is connected to the other draft link by a link member which is pivotally connected to the leg and the draft link. The hydraulic actuator is carried by the support member and connected to the link member for pivoting the link member so as to vertically move the leg to vary the plane of the hitch mechanism relative to the tractor.

Abstract: A hitch for connecting an agricultural implement to a tractor including an A-frame secured to the upper side of a transverse draw bar, the draw bar having a plurality of link-engaging brackets at its opposite ends for engaging the lateral lifting links of the tractor, and further having a clevis bracket at its central portion and on the opposite side of the draw bar from the link-engaging brackets for connecting the tongue of an agricultural implement thereto. The hitch further includes a cylinder-supporting plate projecting from a central crossbar of the A-frame to a position over the clevis bracket and supporting on the upper side thereof, a hydraulic cylinder which has its upper end pivotally connected through a suitable bracket to a plate secured to the apex of the A-frame.

Abstract: A rotary harrow attachment has a frame portion to which coupling elements can be connected in alternative locations so that the attachment can be connected to the front or the rear of a prime mover on a multi-point hitch. The p.t.o. of the prime mover is drivenly connectable to the soil working members by a gear box which is also detachable and repositionable 180.degree. on the frame portion.

Abstract: A coupling assembly for interconnecting a pair of implements such as grain drills in end-to-end relation for towing behind a tractor for field operation and in an endwise direction for transport. The grain drills are connected to a tractor by conventional duplex hitch structure. The grain drills are connected to each other by a novel coupling assembly which in field operation permits the adjacent drills to move within limits toward and away from each other to accommodate ground level variations. The coupling assembly includes a latch unit positionable to lock the coupling assembly to thus retain the drills in fixed spaced relation to facilitate endwise transport of the drills.
