Tube Joint in Implement Frame

An agricultural implement frame comprising at least one beam having a first tube member and a second tube member joined by a tube joint, the tube joint comprising:

• an overlaying portion formed by overlaying ends of the first and second tube members, each overlaying end having an overlaying wall and a base wall connected by opposing interface side walls, wherein the interface side walls have interface surfaces extends from a lip at a distal end of the overlaying wall to a foot in the base wall such that when the first and second tube members are joined together, the interface surfaces in the interface side walls of the first and second tube members contact and the lip of the first tube member abuts the foot of the second tube member and the lip of the second tube member abuts the foot of the first tube member;
• at least one clamping fastener configured to clamp together the overlaying ends of the first and second tube members;
• and
• a plurality of interlocking load transfer teeth in the interface surfaces configured to transfer load between the first and second tube members in the beam.
