A remote tractor control system with a hand held remote control unit having an enable button that when actuated sends signals from a plurality of command buttons on the hand held remote control unit to a three point hitch controller, a transmission controller and an engine controller on a tractor. When not actuated, a rear switch module may be used to raise and lower the three point hitch or creep in forward or reverse, while the hand held remote control unit may display information about tractor condition from the engine controller.

The invention relates to an arrangement for attaching a working tool to a working machine, preferably to a three-point hitch of the working machine, comprising a pushing arm articulated, at one end, to the working machine, and two pulling arms articulated, at one end, to the working machine. The arrangement comprises a coupling mechanism for attaching the three-point hitch, from the cabin of the working machine, to the working tool, or, to a quick hitch positioned between the working tool and the working machine.

One exemplary embodiment is a hitch assembly including forward and rearward lateral members, first and second longitudinal members and a lifting member which are coupled together to form a laterally-articulating pitch-adjustable quadrilateral. The forward lateral member is coupled with the first longitudinal member by a first joint and the second longitudinal member by a second joint. The rearward lateral member is coupled with the first longitudinal member by a third joint and the second longitudinal member by a fourth joint. The lifting member is coupled with the rearward lateral member by a first flexible rigging member and a second flexible rigging member. The quadrilateral can articulate between a left-leaning configuration, a rectangular configuration, and a right-leaning configuration. The lifting member can be adjusted to vary an amount of slack in one or both of the flexible rigging members and to raise and lower the rearward lateral member.

A lift link assembly of a three-point hitch. The lift link assembly includes a yoke, a shaft, and a retractor. The yoke includes a main housing and first and second side arms that extend downwardly therefrom. The shaft includes a shank and a head positioned on a lower-end thereof, and the shank is positioned in the upper-end through hole. When the lift link assembly is in a retracted mode, the retractor is positioned above the head, the retractor is configured to apply a downward force to the head, and the retractor is configured to apply an upward force to the yoke.

A work vehicle includes a travelling vehicle body; a work machine mounted on a rear portion of the travelling vehicle body to be capable of being lifted and lowered; a control unit for controlling lifting and lowering of the work machine; and a rear sensor provided on the rear portion of the travelling vehicle body and configured to detect an object present behind the travelling vehicle body. The control unit may be configured to set a regulation height based on a height where the rear sensor detects the work machine while the work machine is lifted and then regulate lifting of the work machine during work in such a manner that a height of the work machine is kept less than or equal to the regulation height.

Coupling apparatus for coupling a mower to a front three-point linkage of a tractor includes a mounting element for coupling to the three-point linkage and a carrier element to which the mower is coupled. A linkage mechanism including upper link members and a lower link member couples the carrier element to the mounting element. The lower link member is pivotally coupled to the mounting element about a first lower pivot axis. A pair of take-up springs act between the lower link member and the mounting element to take up a portion of the weight of the mower. The take-up springs are coupled between corresponding anchor elements and corresponding anchor brackets on the lower link member. The anchor elements are carried on respective compensating arms, which in turn are pivotal on pivot shafts carried on the mounting element. Actuator arms acting between the lower link member and the compensating arms urge the anchor element upwardly and downwardly as the carrier element moves upwardly and downwardly for controlling the turning moment induced by the take-up springs in the linkage mechanism, in order to maintain the effective weight of the mower bearing on the ground substantially constant.

An attachment system for removably attaching an implement under a vehicle. The mounting system includes a vehicle frame. The vehicle frame has a pair of spaced apart frame portions. Each of a pair of hitch receiving points is connectable with a respective one of the frame portions. An implement includes support structure extending for a length. A pair of hitch pins is associated with the support structure. The hitch pins are spaced apart in a direction along the length of the support structure. Each hitch pin is for attachment to a respective one of the hitch receiving points. A structural member is associated with the support structure and has a portion adapted to attach to structure outboard of a frame portion. A lift mechanism is connectable with a portion of the vehicle frame. The lift mechanism is attachable with the structural member to move the hitch pins relative to the hitch receiving points.

A mobile communications station may include a supporting frame including an interface for mechanical coupling to a vehicle for transporting the mobile communications station, wherein the interface includes fastening points for attachment of a three-point hitch; a first antenna mounted on the supporting frame to facilitate communication with mobile devices; and a second antenna mounted on the supporting frame to facilitate communication with a distant location, wherein the first antenna and the second antenna are to facilitate a bidirectional communication link between the mobile devices and the distant location.

An apparatus for combining planting implements enables an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. The apparatus is rigidly affixed to a conventional cultivating implement and comprises a support frame, a pair of brackets, and a connection bar. In combination, the support frame, pair of brackets, and connection bar provide a three-point connection whereby a conventional broadcasting implement may be attached thereto, thus enabling an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. In operation, at least a portion of the conventional cultivating implements disposed behind the conventional broadcasting implement when the conventional broadcasting implement is attached to the support frame, thereby allowing simultaneous cultivation and broadcasting of constituents,
