A rectangular baler including a baling chamber, an intake duct, a pick-up mechanism for picking up crop material and introducing it into the intake duct, and a stuffer mechanism to selectively execute a packer stroke to advance crop material partially along the intake duct and a stuffer stroke to transfer the crop material accumulated in the intake duct into the baling chamber. The stuffer mechanism includes a tine bar extending between two stuffer assemblies at each side of the baler. Each stuffer assembly includes a first stuffer arm connected at a first pivot point to a first crank arm of a first drive mechanism, a second stuffer arm connected at a second pivot point to a second crank arm of a second drive mechanism, and a coupling plate pivotally mounted around a stationary pivot point. The coupling plate couples the first stuffer arm with the second stuffer arm.

1. A rectangular baler comprising: a baling chamber;a plunger reciprocally mounted in the baling chamber for compressing crop material;an intake duct for accumulating crop material before transfer into the baling chamber;a pick-up mechanism for picking up crop material and introducing the crop material into the intake duct; anda stuffer mechanism configured to selectively execute a packer stroke to advance crop material partially along the intake duct and a stuffer stroke to transfer the crop material accumulated in the intake duct into the baling chamber, the stuffer mechanism comprising two stuffer assemblies at each side of the baler and a tine bar extending between the two stuffer assemblies, and at least one of the two stuffer assemblies comprising: a first stuffer arm connected at a first pivot point to a first crank arm of a first drive mechanism;a second stuffer arm connected at a second pivot point to a second crank arm or disc of a second drive mechanism; anda coupling plate pivotally mounted around a stationary pivot point, the coupling plate coupling the first stuffer arm with the second stuffer arm, wherein the coupling plate is coupled to the first stuffer arm through a connection configured to allow a predetermined limited movement of the first stuffer arm with respect to the coupling plate, and wherein the coupling plate comprises a top corner and a bottom corner,wherein the second stuffer arm is pivotally connected to the coupling plate at a pivot point located between the top and bottom corners of the coupling plate, andwherein the tine bar is connected to the first stuffer arm. 2. The rectangular baler of claim 1, wherein the connection is a slot-pin connection. 3. The rectangular baler of claim 2, wherein the coupling plate has a slot as part of the slot-pin connection, and wherein the first stuffer arm is provided with a pin which is moveable in the slot. 4. The rectangular baler of claim 3, wherein the first stuffer arm has a bottom end and a top end, wherein the first pivot point is located nearer to the bottom end than to the top end, and wherein the pin is located nearer to the top end than to the bottom end. 5. The rectangular baler of claim 1, wherein the first drive mechanism is configured to rotate at a first rotational speed which is a multiple of a second rotational speed of the second drive mechanism. 6. The rectangular baler of claim 1, wherein the stationary pivot point has a pivot axis which corresponds with a rotational axis of the first drive mechanism around which the first crank arm rotates. 7. The rectangular baler of claim 1, wherein the stationary pivot point around which the coupling plate is pivotally mounted is in a lower half of the coupling plate, and wherein the lower half of the coupling plate is the area of the coupling plate below half of a height of the coupling plate when the coupling plate is in a highest position. 8. The rectangular baler of claim 7, wherein the coupling plate has a slot as part of the slot-pin connection,wherein the first stuffer arm is provided with a pin which is moveable in the slot,wherein the slot is provided in an upper two thirds of the coupling plate, andwherein the upper two thirds of the coupling plate is an area of the coupling plate above one third of the height of the coupling plate when the coupling plate is in the highest position. 9. The rectangular baler of claim 7, wherein the first stuffer arm has a bottom end and a top end, wherein the first pivot point is located nearer to the bottom end than to the top end,wherein the pin is located nearer to the top end than to the bottom end, andwherein the coupling plate is pivotally connected to the second stuffer arm at a pivot point which is located between the slot and the stationary pivot point. 10. The rectangular baler of claim 3, wherein the slot of the slot-pin connection is substantially straight. 11. The rectangular baler of claim 3, wherein the slot of the slot-pin connection is oriented at an angle with respect to a vertical direction, the angle being smaller than 30 degrees in a highest position of the coupling plate. 12. The rectangular baler of claim 1, wherein the first pivot point of the first stuffer arm is nearer to the intake duct than the second pivot point of the second stuffer arm. 13. The rectangular baler of claim 2, wherein the coupling plate is a polygon, having the bottom corner and the top corner, wherein the stationary pivot point is closer to the bottom corner than to the top corner, and wherein the slot-pin connection is closer to the top corner than to the bottom corner. 14. The rectangular baler of claim 1, wherein the connection comprises a crank arm or disc, and wherein a first point of the crank arm or disc is connected pivotally to the first or second stuffer arm and a second point of the crank arm or disc is connected pivotally to the coupling plate.
