Abstract
A flexible joint accommodates relative horizontal motion between the main pipeline of a center pivot irrigation machine and a swing span without unduly stressing the spans. The flexible joint has a spindle mounted for rotation about a vertical axis in a socket at the outer end of the main pipeline section. The spindle has a horizontal pivot shaft mounting an arm assembly for rotation about the shaft. The opposite end of the arm assembly carries a second pivot shaft pivotally mounting a link. The swing span is attached to the link. A brake is provided to limit coasting of the swing span.
