    Abstract: An agricultural toolbar employs at least two wing assemblies for following the contour of the land in a working position and foldable to a transport position for transit on public roads. The principal use in working position benefits from having a wide range of movement to accommodate variations in land contours and soil types. The principal use in transport mode benefits from having a compact configuration to better meet road regulations. End-uses that condition cultivatable land at multiple locations will benefit from the toolbar.

    Abstract: A land roller implement is towed by an agricultural tractor for levelling land. The implement has a main frame and two wing assemblies pivotal from a working field position extending laterally outward in opposing directions from the main frame to a transport position extending rearwardly from the main frame. The implement has a set of transport wheels for transporting the rollers of the implement spaced above the ground in the transport position, the wheels including: (i) two leading wheels on the main frame, (ii) two trailing wheels at the outer ends of wing assemblies, and (iii) two steerable wheels supported on the wing assemblies forwardly of the trailing wheels. The steerable wheels can be controllably pivoted by an actuator into a transport configuration oriented for forward rolling in transport, while the other wheels are freely pivotal to shorten the turning radius of the towed implement.

    Abstract: In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm (46); a pair of wheel connecting assemblies (44A, 44B), each comprising a hub (60A, 60B) and a spindle (58A, 58B); a pair of mounts (50A, 50B) coupled respectively to the pair of wheel connecting assemblies; a pair of wheels (52A, 52B) coupled respectively to the pair of wheel connecting assemblies, the pair of wheels separated by the tandem wheel arm and in a same fore-and-aft position; and plural pairs of parallel links (48A, 48B) of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

    Abstract: A towable agricultural implement, having a center frame and two wing frames pivotally coupled on the center frame to move between a field frame position extending laterally outward and a range of transport positions extending generally rearward, further includes a transport wheel on each wing frame that is pivotal about an upright steering axis through a range of wheel positions including a neutral transport wheel position for rolling forwardly. Each transport wheel is pivotal from the neutral transport wheel position in either one of two opposing steering directions under control of a steering actuator through an overall range of greater than 90 degrees. The wheels can be steered in a common direction during transport. A control system can also attempt to maintain a constant angle between the center section and the wings to allow reversing while in transport mode.

    Abstract: Arrangement for positioning mechanisms of seed drill machines for transport, preferably of the “auto trailer” type, including at least one toolholder bar, with their respective sowing units, divided into a central piece coupled to the structure of the chassis, and two side pieces, one at each side of the central piece, which pivot in a horizontal plane for being folded, with the corresponding sowing units, from the working position of the seed drill to the transport position parallel to the longitudinal axis of the chassis. The toolholder bar is mounted on a cart attached by guide plates to a lift tower and moves both up and down along said tower by triggering hydraulic cylinders. The lift tower is coupled to mobility device, with the toolholder bars and sowing units, from the working position to the transport position of the seed drill, and vice versa. The transport position is defined in a section of the drawbar next to the attachment end of a transportation tractor of the machine.
