An agricultural baler includes a main bale chamber, a plunger reciprocally movable within the main bale chamber, and a stuffer unit including a tine arm defining an axis of rotation and a plurality of tines coupled with and extending from the tine arm. The tines are rotatable around the axis of rotation of the tine arm between a first position associated with a stuffing cycle and a second position associated with a loading cycle.

Systems, apparatus, and methods for use with mergers for processing a material on a ground surface includes detecting, via one or more sensors, an object of interest associated with the material when a merger is forming a windrow on the ground surface. The method also includes a step for facilitating removal of the object of interest from the material in response to the detection.

A movable tractor-trailer combination includes a self-powered tractor having a plurality of ground-engaging members and a steering mechanism for steering at least one the ground-engaging member; and a trailer that is towed behind the tractor and that is connected to the tractor by a drawbar that is pivotably connected at a tractor connection to the tractor. One or more sensors sense a line of a swath of crop material corresponding to a maximal quantity of crop material per unit length of the swath. The tractor-trailer combination includes a control apparatus that operates in dependence on at least one output of the one or more sensors to operate the steering mechanism of the tractor in dependence on the at least one output such that the tractor moves along the swath without any of the ground-engaging members running over the swath.

A forage harvester including a header for picking up a swath from a ground surface. The header includes a first and a second distance sensor adapted to measure a sensor-to-target distance respectively along a first and second sensor axis. The first distance sensor is mounted at a first lateral end of the header, and the second distance sensor is mounted at a second lateral end of the header. The first and second distance sensors are positioned such that, when the forage harvester is placed on an even ground surface, the first sensor axis crosses the second sensor axis before reaching the even ground surface in front of the harvester.

A baler combination includes a towing vehicle and a baler pulled by the towing vehicle by means of a drawbar. A control unit is connected to a drive system of the towing vehicle, the baler and an actuator. An angle between the drawbar and the baler is able to be set and/or adjusted by the actuator. The control unit is operable to control the drive system and/or the actuator such that the baler combination is moved from a first position to an unloading position, to actuate the baler such that a bale is unloaded at the unloading position, and to actuate the drive system and/or the actuator such that the baler combination is moved back from the unloading position to the first position.

The invention concerns improvement of a ground-traversing collection machine of a type having a laterally spanning pickup reel, a wind-guard residing overhead of the pickup reel and featuring a laterally lying support and a plurality of hold-down tines projecting from the support bar in a longitudinally rearward direction of opposing the machine's travel direction to hold down the material as it is fed rearwardly from the pickup reel, and a set of stub augers positioned adjacent opposing ends of the pickup reel to convey the material laterally inward toward a midplane of the machine. In the inventive improvement, a set of one or more tine braces are installed on the wind-guard in positions reinforcing one or more of said hold-down tines against potential deflection thereof by the material during laterally inward conveyance thereof by the stub augers.

An agricultural baler includes a main bale chamber, a plunger reciprocally movable within the main bale chamber, and a stuffer unit including a tine arm defining an axis of rotation and a plurality of tines coupled with and extending from the tine arm. The baler is characterized in that the tines are rotatable around the axis of rotation of the tine arm between a first position associated with a stuffing cycle and a second position associated with a loading cycle.

A large square baler for performing a baling operation to form square bales includes a pickup unit for picking up crop lying on the ground, a cutter unit for cutting picked up crop into at least one predetermined cut length, a pre-compression chamber, a stuffer device, a bale chamber for forming a square bale from flakes of crop pre-compressed in the pre-compression chamber, and a tying system for binding the square bale. The stuffer device is configured to pre-compress the crop into the flakes in the pre-compression chamber and transport the flakes into the bale chamber. The cutter unit is controlled in dependence on a tying operation conducted by the tying system and on at least one parameter representing the square bale size.
