Abstract:
A forage crop harvester (11) provided with a rotary crop pick-up (30) which deposits crop deposited in an elongated swath and deposits it on a transversely extended, moveable conveyor (36) which consolidates the crop material and deposits it in a windrow at one side of the harvester (11). According to the disclosure, the pick-up (30) is deposed on the harvester in a position in advance of the harvester wheels (21), thereby eliminating damage to the crop caused by crushing of the material in the swath by the wheels (21). The harvester (11) includes mechanism (17, 23, 24) providing for maintaining it in an offset relationship with respect to the tractor (10) during operation. The rake (30) and conveyor (36) are supported through a counterbalancing mechanism (46) which maintains it in a floating relationship in a crop pick-up position and has ground engaging skids (52) which limit contact of the rake teeth (31) with the ground surface.
Abstract:
The present invention concerns a haymaking machine comprising a chassis (2) supported on the ground by wheels (6) and a working device (11) linked to the chassis (2), the chassis (2) comprising a coupling device (4) to which two coupling parts (18a, 18b) are hinged, each carrying a journal (17a, 17b) for coupling to the respective lower arms of a tractor (5), each coupling part (18a, 18b) engaging with a respective return device (21a, 21b), each return device (21a, 21b) storing energy when the corresponding journal (17a, 17b) moves, relative to the coupling device (4), upwards from a first position, and each return device (21a, 21b) being able to restore this energy to the corresponding journal (17a, 17b) by bringing the journal (17a, 17b) back to the first position. The invention is remarkable in that each return device (21a, 21b) stores energy when the corresponding journal (17a, 17b) moves, relative to the coupling device (4), downwards from a second position, and each return device (21a, 21b) can restore this energy to the corresponding journal (17a, 17b) by bringing the journal (17a, 17b) back to the second position.
Abstract:
A mower (8) towed by a tractor (7) and having a pass width (A) is provided with a rearwardly projecting shielding device (10) to define a discharge opening (11) for discharging cut crop in a windrow (3 to 6) at a swath width (B) substantially shorter than the pass width (A). The discharge opening (11) is positioned asymmetrically in relation to the pass width (A) substantially within an area which at one side is defined by the centre line (C) of the mower (8) and at the other side by the fact that the distance (D) to the nearest extreme limit of the pass width (A) is equal to or larger than half the difference between the external track width (T) of the tractor (7) and the swath width (B) of a windrow. The crop is then discharged in pairs of windrows (3 to 4, 5 to 6) immediately adjacent each other so that two windrows may be collected in one operation by means of a crop pickup attachment (13) having a collecting width equal to or smaller than the pass width (A) of the mower (8). In order to prevent the tractor during cutting from running over already cut crop the drawbar (9) of the cutter (8) is provided with an asymmetrical deflection relative to the centre line (C).

L'invention est remarquable en ce que chaque dispositif de rappel (21a, 21b) emmagasine de l'énergie lorsque le tourillon (17a, 17b) correspondant se déplace, par rapport au dispositif d'attelage (4), vers le bas depuis une deuxième position, et que chaque dispositif de rappel (21a, 21b) peut restituer cette énergie au tourillon (17a, 17b) correspondant en ramenant le tourillon (17a, 17b) vers la deuxième position.
Abstract:
A mower is suspended from a frame (11) and includes a header (13) with a cutter (17). A tongue (21) is pivotally connected to the mower frame (11) and is moveable with respect to the frame by a hydraulic cylinder (16). At the front of the tongue is a front gearbox (31) rigidly attached to the tongue (21). The front gearbox (31) transmits rotary power from the power take off of the tractor to a rear gearbox (51) pivotally attached the header and from the rear gearbox rotary power is passed on ultimately to the rotary cutting units. Pivoting of the rear gearbox is controlled by a steering connection (64,65) operatively attached between the front and rear gearboxes.

Abstract:
A drive arrangement for a harvesting header (22) of a harvesting machine (10) having a running gear on which a feeder housing(20)is mounted. A front side of the feeder housing has a header mount (21) that moves relative to the feeder housing and on which the harvesting header(22) is detachably fastened. An automated coupling mechanism (32) is provided to link a driven shaft (33) from the harvesting machine to a drive shaft (34) of the harvesting header as the header is connected to the harvesting machine. The drive connector (45) connected with the header mount (21) is movable relative thereto during the attachment of the harvesting header to axially align the driven shaft and drive shaft as the harvesting header approaches the feeder housing during the attachment to accommodate differing header drive shaft orientations.
Abstract:
A swing-tongue harvester (10) has a hydraulically controlled pulling tongue (30) that can be operated from the tractor seat to change the lateral position of the machine relative to the towing tractor (36), notwithstanding the presence of a mechanical drive line (90) which extends along the tongue (30) and branches down to a gearbox (116) carried by the header (50) for driving the operating components of the header (50). Telescoping steering linkage (138) between the swing tongue (30) and the gearbox (116) causes the gearbox (116) to swing responsively with the tongue (30) when the tongue is swung to any of its angular positions, thus keeping the input shaft (114) of the gearbox (116) oriented properly toward the driveline (90) along the tongue (30). The connection points for the steering linkage (38) between the tongue (30) and the gearbox (116) are such that a telescoping section (106) of the driveline (90) bridging the tongue (30) and the input shaft (114) of the gearbox (116) has equal angles maintained at its universal joints (104, 110) at opposite ends of the telescoping section (106) to reduce unequal loading at those locations. Specifically configured impeller plates (186) associated with the left and right, endmost rotary cutting units (172) on the cutter bed of the header (50) assist in proper delivery of the cut materials rearwardly into the discharge opening (65) of the header (50).
