Skid-steer type power unit engageable with an implement using an attachment assembly including an attachment frame and a hitch. An arcuate frame member is located forwardly of the attachment frame and is engaged therewith in such a way that the frame member pivots about a vertical axis located forwardly of the frame member and generally centrally positioned relative to the attachment frame. The frame member pivots in response to actuation of a hydraulic cylinder. The power unit includes a system for transferring weight of the implement rearwardly onto the power unit. A belt-drive power-take off system on the power unit powers the implement's operation. An underbelly drop spreader is located between the front and rear wheels of the power unit and a brine delivery system distributes brine from nozzles located rearwardly of the rear wheels. A unique control panel permits operation of all systems on the power unit and implement.

Adapter (27) of an agricultural implement, having a first, cylindrically contoured section (27a), the external diameter of which is designed to couple the agricultural implement to a US quick-hitch attachment system of an agricultural support vehicle, and having a second, spherically contoured section (27b), the external diameter of which is designed to couple the agricultural implement to a European lower-link attachment system of an agricultural support vehicle.

An attachment assembly for connecting an agricultural implement to a tractor. The attachment assembly comprises a tractor-side frame configured to extend from a rear of the tractor, and an implement-side frame configured to be removably attached to the implement. The implement-side frame is configured to rotate with respect to the tractor-side frame.

A U-shaped drive frame has abase beam and parallel side beams defining an open implement area. Drive wheels support the side beams, and each drive wheel rotates about a horizontal drive wheel axis perpendicular to the operating travel direction. A steering control steers the drive frame in the operating travel direction. Implements are configured to perform implement operations and to rest on the ground surface when in an idle position. The drive frame moves rearward to a loading position where each implement is movable to an operating position supported by the drive frame. Each implement provides a beam lock connection between the side beams that resists twisting movement of the side beams to maintain the drive wheels and the side beams in a substantially fixed relationship with respect to each other.

An implement operating apparatus has a U-shaped drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A power source is connected through a drive control to rotate the drive wheels in either direction. First and second implements are configured to perform implement operations and to rest on the ground and when the drive frame is maneuvered to an implement loading position with respect to each implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a first travel path or a second travel path oriented generally perpendicular to the first travel path.

Device for coupling two shafts end-to-end, comprising a pair of dog clutch members (16, 28).

Each dog clutch member is configured so as to be able to be secured to an end of a shaft to be coupled, and the two dog clutch members (16, 28) have complementary shapes.

A first dog clutch member (16) is pivotably mounted in a first casing (6).

A second dog clutch member (28) is pivotably mounted in an intermediate bearing (8).

The intermediate bearing (8) is slidably mounted in a second casing (10) assumed to be fixed, the intermediate bearing (8) being able to slide relative to the second casing (10) in a direction parallel to the two shafts to be coupled, termed the longitudinal direction.

The intermediate bearing (8) is elastically prestressed in the direction of the first casing (6).

A mounting bracket for mounting a front three-point hitch on a tractor includes a linking part for articulated mounting of the front three-point hitch, a connecting part for coupling the linking part to a support structure of the tractor, and a first contact region defined on the linking part and a second contact region defined on the connecting part. The first contact region interacts with the second contact region for coupling the linking part to the connecting part. The first contact region and the second contact region are separably clamped to one another in a coupling position. The linking part is selectively disposable in one of a plurality of coupling positions relative to the connecting part.

A hitch device for an implement is capable of being mounted on an agricultural vehicle, including: a first chassis extending in a vertical plane, the normal to which is substantially the direction of travel of the hitch; a second chassis also extending in the vertical plane and mounted with capacity for translational movement on the first chassis in the transverse direction with respect to the direction of travel of the hitch; an actuator causing the translational movement of the second chassis with respect to the first chassis; an attachment device for fixing the first chassis to the rear of the agricultural vehicle; and a system for attaching an agricultural implement, the system allowing the implement to pivot about the vertical.

An apparatus for connecting an implement to a three point hitch of mobile machinery comprises two frameworks, a first framework and a second framework. The first framework is disposed in a first plane and comprises at least two parallel, vertically-spaced apart, laterally extending rails. There are three attachments supported by the first framework for attachment to the three-point hitch. The second framework is slidable generally in the plane of the first framework and is mounted on the rails to slide laterally along the rails. At least two connectors are supported by the slidable second framework for connecting the second framework to an implement that can be pulled or pushed by the mobile machinery. A driver is connected to the first framework and connected to the second framework for driving the second framework laterally back and forth along the rails of the first framework.
