The structure has interconnected frame beams that are supported on ground wheels and the rear ends of the forwardly extending beams are fixed to vertical frame beams. Rearwardly extending arms are pivoted to the interconnected frame beams and these arms together with coupling plates on an upper tie beam, form a rear three point coupling. The arms are interconnected to the remainder of the structure by adjustable carrier arms. Ground wheels support the structure and a further implement that is connected to the rear coupling.

Abstract: An agricultural implement has a driven rotor with cultivator blades and a hood that overlies the rotor. The hood extends down to the rear and the lower hood portion is a guide that has a row of teeth. The teeth are extensions that furrow the worked soil and each tooth corresponds to a material delivery duct that communicates material, such as seeds, from a hopper to the furrows. A ground engaging trough-like levelling member is adjustably connected to side plates of the hood and the openings of the ducts are positioned near the levelling member to prevent clogging of the openings. One or more rear rollers are arranged behind the levelling member with driving connections to a rotatable mechanism in the hopper.

Abstract: A rotary harrow or cultivator has a frame including an elongated frame portion that supports a row of soil working members. Each soil working member has a substantially vertical shaft supported on the frame portion by upper and lower bearing connections. The shafts each have a pinion gear in mesh with neighboring pinion gears and these gears are housed within the frame portion between the upper and lower bearing connections. If the upper bearing fractures, the fragments thereof are retained by a protective member which can be a separate plastic annular member having a chamber that surrounds each shaft, or the bearing connection can be formed by two separable portions that are bolted together and secured in a top cover of the frame portion. In either case, the bearing fragments are retained and cannot become lodged between the meshed gears.

Abstract: A haymaking machine has a pair of rotatable rake members that are driven to turn in relative opposite directions about upwardly extending axes, towards one another to pass crop between them. Outwardly extending tines on the rake members define circular paths that intersect or are closely adjacent one another during operation. Beginning at the front of the rake members, with respect to the normal direction of travel, a pair of crop feeders are positioned to guide crop between the rake members and towards the intersecting paths of their tines. The feeders comprise downwardly extending elements that can be curved or configured to shed crop adjacent the ground, near the rotating tines. Further feeders of similar structure are positioned to the rear of the forward pair but within the paths traced by the tines, when viewed in plan. The feeders can be adjustable in a vertical direction and/or deflectable against spring opposition to accommodate heavy crop.
