Auger coupling assembly with a pivotable clutch

A farm implement comprising:

• a frame;
• a container mounted on said frame and configured to hold agricultural material;
• and
• an auger assembly configured to convey agricultural material held in the container, wherein the auger assembly comprises:
• a first auger section comprising a first auger shaft configured to rotate in a conveying direction about a longitudinal axis of the first auger section and a first helical flight array disposed along and projected from the first auger shaft;
• a second auger section comprising a second auger shaft configured to rotate about a longitudinal axis of the second auger section and a second helical flight array disposed along and projected from the second auger shaft;
• a folding joint assembly coupled to the first and second auger sections and comprising a folding axis, the folding joint assembly is configured to rotate the second auger section about the folding axis between a transport position and an operating position;
• and
• an auger shaft coupling assembly configured to releasably connect an end of the first auger shaft to an end of the second auger shaft when the second auger section is in the operating position, wherein the auger shaft coupling assembly comprises:
• a first auger coupling portion coupled to the end of the first auger shaft;
• a second auger coupling portion coupled to the end of the second auger shaft, the first auger coupling portion comprising a lobe,
• a drive pin secured to the second auger coupling portion;
• and
• a latch arm configured to pivot in a direction substantially parallel to the longitudinal axis of the second auger section between an engaged position and a disengaged position;
• wherein the second auger coupling portion is configured to at least partially receive the first auger coupling portion;
• wherein the lobe is configured to rotationally engage the drive pin in the conveying direction when the first auger coupling portion is at least partially received in the second auger coupling portion, such that rotation forces are transmitted from the first auger shaft to the second auger shaft;
• and
• wherein the latch arm is configured to rotationally engage the lobe in the conveying direction when the latch arm is in the engaged position, such that the latch arm maintains the lobe adjacent the drive pin or within a predetermined degree of separation from the drive pin.
