Rectangular baler with improved stuffer mechanism

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;
• and
• a 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;
• and
• a 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, and
• wherein the tine bar is connected to the first stuffer arm.
