Abstract: A loader includes a tool carrier arranged on a loader boom. The tool carrier is connected at a first pivot point to the loader boom and at a second pivot point to a pivot linkage. The pivot linkage has first and second links which are pivotably connected to one another at a first link point. The first link is pivotably connected at a second link point to the loader boom, and the second link is pivotably connected at a second link point at the second pivot point to the tool carrier. A sensor senses a pivot angle between the tool carrier and loader boom. The sensor is positioned in a cavity on the loader. An actuating device is connected to the sensor.

Abstract: A front loader (10) for a tractor with a parking stand unit (28) including a parking support (30) pivotably mounted on the front loader arm (12). A locking brace (32) is pivotably seated at one end on the parking support (30) and is movably guided at the other end by a guidance means (50) formed on the locking brace (32) and at least one guide groove (48, 49) formed in the parking support (30). The guidance means (50) can be brought by pivoting the parking support (30) into the parking position (P3) into a locking position in which it comes to rest at a stop (66) formed in the guide groove (48, 49). The guidance means (50) can be pressed against the stop (66) and fixed in the locking position by a support force of the front loader arm (12) acting in the parking position (P3) on the locking brace (32).

Abstract: A front loader arrangement (12) with a mounting frame (16) and mounting mast (18) is proposed, wherein the mounting mast (18) can be coupled to the mounting frame (16) and can be decoupled therefrom. Furthermore, a loader arm (20) is connected to the mounting mast (18) for being pivoted vertically by a hydraulic cylinder (24) extending between the loader arm (20) and the mounting mast (18). In order to facilitate coupling of the mounting mast (18) to the mounting frame (16), it is proposed that a hydraulic system (85) be coupled to the hydraulic cylinder working chamber(s) (90, 96) and include adjusting means by which the hydraulic cylinder (24) can be brought into a floating position when the hydraulic fluid supply is decoupled from the hydraulic system (85).

Abstract: A front loader arrangement includes a hydraulically sprung lift cylinder arrangement coupled between opposite loader arm sides and respectively mounting masts. In order to permit the masts to pivot freely about their pivotal connections with the loader arm sides to aid the coupling of the masts to respective mounting frames fixed to a carrying vehicle, the hydraulic system in which the lift cylinder arrangement is incorporated includes a device, including a shut-off valve and an accumulator arrangement for establishing a float condition in the lift cylinder arrangement after a source of hydraulic fluid and associated control valve is decoupled by separating a hydraulic quick coupler.

Abstract: A front loader arrangement (12) with a mounting frame (16) and a mounting mast (18) is proposed, wherein the mounting mast (18) can be coupled to the mounting frame (16) and can be decoupled therefrom, and wherein a locking device for locking the front loader arrangement (12) is provided, which locking device comprises a pivoting locking bar (54) which is pivotable between a locking position and an unlocking position. In order to enable a simple coupling and decoupling, it is proposed that the pivoting locking bar (54) comprises adjusting means which are designed in such a manner that a pivoting movement of the pivoting locking bar (54) into the locking position is blocked upon a relative movement between the mounting mast (18) and the mounting frame (16) for decoupling purposes and is released upon a relative movement between the mounting mast (18) and the mounting frame (16) for coupling purposes.

Abstract: A pull-type mower-conditioner has a windrow grouper mounted to its main frame by a mounting frame that is swingable between lowered working and raised non-working positions. The grouper includes a conveying arrangement defined in part by a belt conveyor mounted to the mounting frame for free pivotal movement, between angularly spaced stops, about a transverse horizontal axis. When the mounting frame is in its working position, the crop-receiving surface of the conveyor is inclined at a slight angle downward toward the rear of the mower-conditioner with gravity holding the conveyor in position against one of the stops. When the mounting frame is in its non-working position, gravity holds the conveyor in a position rotated against the other of the stops, the crop-receiving surface then being almost vertical so that the grouper is almost within the length of the mower-conditioner.

Abstract: A towed farm implement includes a set of auxiliary wheels mounted for elevating the implement to a height which permits the implement to be pulled over and lowered onto a transport trailer or which permits the trailer to be otherwise maneuvered to a loading position beneath the implement. Once the implement is loaded, a pivoted tongue of the implement is positioned so as to be used for the endwise transport of loaded implement. In one embodiment, the auxiliary wheels are mounted on their own lift arms for being swung vertically by an adjusting mechanism that is independent of that use to effect vertical adjustment of the ground wheels. In another embodiment, the wheel support arms of the ground wheels and the lift arms to which the auxiliary wheels are mounted are secured together for being swung by the same adjusting mechanism.

Abstract: An implement draft tongue is moved through a range of working positions to a transport position extending transverse to the working direction of the implement by an extensible and retractable hydraulic actuator. A control for the hydraulic cylinder includes an interrupter valve that is actuated, in response to a preselected extension of the hydraulic cylinder so as to prevent the cylinder from extending beyond a position for moving the draft tongue to one extreme of its operating range, when an actuating device for the interrupt valve is enabled. When the actuating device for the interrupt valve is disabled, the hydraulic actuator may be extended fully to place the draft tongue in its transport position.
