The sensor is designed to detect the vertical force component acting between the tongue or the tractor vehicle and the first coupling element. The first coupling element is pivotably connected to the tongue or the tractor vehicle such as to be pivotable about a horizontal pivot shaft. The first coupling element is also connected to the second coupling element such as to be movable about an axis running parallel to the pivot shaft.

Abstract: A wrapping means tensioning device is provided for a round baler and comprises an idler assembly and an application assembly. Wrapping means, like net, when drawn during a wrapping cycle acts onto the idler assembly, which in turn will press an application element of the application assembly against a roll, on which wrapping means is stored. This provides for proper tension during a wrapping cycle without the need for springs or the like, the force of which would need to be overcome, when a wrapping device is brought into a non-operative loading mode.

Abstract: A crop collecting assembly includes a first collecting unit located between a pair of further collecting units. All of the units operate to gather crop from the ground and feed it to the rear where it may fall to the ground or enter a harvesting machine, such as a self-propelled baler, for further processing. At least one of the further collecting units is adjustable laterally so as to be spaced from the first collecting unit, and a crop-transferring bridging element is provided in the space between the two units for receiving crop from the further collecting unit and delivering the received crop to the first collecting unit.

Abstract: A round baler of the variable chamber type is provided with a pivot arm having mobile rolls which in cooperation with stationary rolls form loops of a baling member. The pivot arm is journalled substantially above a bale chamber and is pivotably mounted so as to be able to pivot through an upper front area of the bale chamber.

Abstract: An agricultural press has material receiver for picking up a swath of crop material from the ground and delivering it to the press chamber. A material hold-down device extends over the material receiver and is mounted for vertical movement relative to the material receiver. During normal operation the hold-down device moves over a first range of movement in response to changing swath thicknesses. If a material jam should nevertheless arise, the material hold-down device can be moved in total or in part, either mechanically or manually, over an second range of movement in addition to the first range of movement in order to be able to liberate the wedged material.

Abstract: A round baler is provided with a single set of belts, which are rotated over a series of fixed and mobile rolls. In order to form a bale of a large diameter several loops are formed in the belts, which loops are controlled by two pivot arms. On a first pivot arm at least three rolls are provided, of which one is an idler roll, and on the second pivot arm at least one idler roll is provided, which all create loops to avoid slack in the belts.

Abstract: In an agricultural machine, for example a round baler, rollers are provided. The roller bodies are composed of a stably configured mounting and a casing which can be fastened thereon. This enables the casings to be manufactured more simply and at lower cost.

Abstract: A rotobaler is provided with an inclination sensor that recognizes an inclination to the side as well as in the longitudinal direction. This inclination sensor generates a signal coupled to a computer that, in turn, controls a display arrangement in order to indicate whether a base that is to be unloaded from the rotobaler can be safely unloaded considering the existing inclination of the rotobaler. In the event an unsafe inclination is present, either the computer sends out a control signal which blocks an operation for depositing the bale on the ground, or causes the bale to be oriented in such a way during the discharge process that the longitudinal centerline of the bale is parallel to the inclination of the slope.

Abstract: A baler includes a baling chamber provided with two walls located opposite each other, and at least one sensor for the detection of the moisture content of a bale located between the two walls being mounted to one of the walls and having sensing area commensurate with that of the entire wall, with the sensor interacting with a contacting surface of the bale and being coupled to a bale moisture evaluation arrangement.

Abstract: A loading arrangement is proposed for the wrapping material roll of a wrapping assembly, in which the wrapping material roll can be deposited on a carrier and moved into an operating condition, where it is secured in this position by several rolls.

Abstract: A round baler has an unloading apparatus downstream of a bale chamber provided with movable carrying elements, for example rollers, belts, etc., so that a round bale discharged in rotating motion from the bale chamber is able to maintain its spin and twine wound onto it does not fall off again. To prevent the rotary motion of the round bale from being slowed or even terminated upon transfer to the unloading apparatus, stationary portions of a superstructure of the round baler, for example, a cross-stay serving as an axle, are covered by a movable cover.

Abstract: A large round baler includes a bale forming assembly and a chassis constructed as separate units which, when disconnected and displaced from each other either entirely at an interface between the units or by tilting one unit about a longitudinal axis at one side of the interface, permit one or more flexible endless baling elements to be mounted in place on the baling assembly. Cross beams, which extend between and interconnect the opposite side structures of the bale forming assembly are located such, that they do not obstruct the space required to slide the endless baling element(s) over the baling assembly and into engagement with the bale forming rolls. Mounting of the flexible endless baling element requires the removal of one or more baling element support rolls from opposite side structures of the baling assembly and/or from opposite arms of a tensioning assembly.
