A knee joint assembly for an agricultural implement or a vehicle includes a relatively short knee casting with an apertured end of rectangular cross section which is inserted in a mating steel knee tube. The apertures in the casting end align with beveled apertures in the side walls of the knee tube. Steel pins of length approximately equal to the spacing of the side walls are pressed into the casting through the beveled apertures. Groove welds then secure the steel pins to the knee tube. The casting is relatively small and does not require any welding. Inexpensive ductile iron and common steel tubes can be used for most or all of the assemblies on a machine. The apertured end of the casting includes concave walls to accommodate knee tube concavity and weld flash on the inside of the knee tube.
