A harvester according to the invention comprises a header (1) attached at the front face of a feeder (8) mounted at the front of the main harvester body. The main driveline of the harvester is coupled to the driveline of the header by a releasable clutch, the first part (24) thereof being located at the side of the feeder housing (11). The second clutch part (25) is rotatably coupled to a header driveshaft. According to the invention, the header (1) comprises a spring-operated assembly comprising a holder (30) that is pivotably connected to the header frame and a support arm (31) that is movable relative to the holder along its own longitudinal axis.The second clutch part (25) is pivotably connected to one end of the support arm (31). A spring (32) maintains the support arm in a position lying upwards of the first clutch part (24) when the header driveline is decoupled from the main driveline. The holder (30) is pivotable according to sufficient degrees of freedom to allow pulling the second clutch part (25) from the upward position against the spring force and coupling it to the first clutch part (24). The spring-operated assembly furthermore enables the movement of the header (1) relative to the feeder according to one or two degrees of freedom, while the clutch parts remain interlocked.
