A windrower has a crop merger attachment with a conveyor configured to receive crop material from a crop conditioning mechanism and direct the crop material to a side of the windrower, the crop merger attachment being mounted for adjusting movement between a lowered and a raised position. The windrower has a swathboard mounted for adjusting movement between a fully raised position in which the crop material passes beneath the swathboard for engagement with the merger attachment and a lowered position in which the crop material down to the ground under the merger attachment under the windrower. A control system automatically adjusts movement of the swathboard when movement of the merger attachment is detected.

Harvesting apparatus, with a supporting frame (12) having a longitudinal member and crossmembers, pickup members (20) and transverse conveyor devices (21), wherein a respective pickup member and transverse conveyor device are arranged on a first and second side of the longitudinal member (13), wherein a first shiftable crossmember (14) is shiftable about an axis (24) and is furthermore shiftable via the second crossmember about an axis (25) extending in the longitudinal direction relative to a fixed crossmember (16), and wherein a first overload protection device (26) is positioned between the first and second shiftable crossmembers (14, 15), said overload protection device triggering when a force on the respective pickup member (20) and/or the respective transverse conveyor device (21) and/or the respective first crossmember (14) exceeds a limit value and permitting shifting of the respective pickup member (20) and of the respective transverse conveyor device (21) rearwards about the axis (24).

A machine for the harvesting of plants comprises an arm movable between work and transport configuration, a tool comprising lateral ends and being able to occupy a work position and another position, a connecting device via which the tool is connected to the arm and enabling a first movement of the tool relative to the arm, during which the lateral ends move vertically relative to the arm in the same vertical direction relative thereto, the connecting device can operate a second transverse and horizontal movement of the tool relative to the arm and making it possible to operate this second movement independently of the first movement. The connecting device comprises an arm articulated on the support arm about a first transverse and horizontal axis when the support arm is in the work configuration, and this arm can, by pivoting about the first axis, moved vertically relative to the support arm.

A merger, for picking up and distributing materials from a ground surface, includes a frame that provides support to the merger, a pick-up head affixed to the frame that lifts the materials from the ground surface, a height adjustor affixed to the frame that maintains a minimum clearance between the ground surface and the pick-up head, and a conveyor affixed to the frame that receives the materials from the pick-up head. The conveyor includes a first belt and a second belt that independently distributes the materials on the ground surface from at least one of a first side of the frame and a second side of the frame.

An agricultural machine including a frame, at least one operating unit connected to the frame, at least one wheel or crawler track rotatably attached to the frame to allow the movement of the machine on a supporting surface and a lifting unit operatively interposed between the frame and the wheel or between the frame and the operating unit, configured to vary the height of the operating unit with respect to the supporting surface of the machine. The lifting unit includes at least one hydraulic cylinder provided with a liner, a first and a second piston both slidingly housed inside the liner and arranged in series to define at least a first and a second chamber inside the liner, wherein the first and the second piston can be controlled independently of each other.

Provided are systems, apparatus, and methods for use with mergers. A method 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.
