ABSTRACT:
A folding system for large, agricultural implements which includes special stops, push-off arms, and support stands to avoid putting excessive strain on the hydraulic system or the implement. Special floating links are also provided on each wing section of the agricultural implement which cooperate with the push-off arms and the support stands to limit the strain placed on the folding system. In addition, the floating links allow the unfolded wings of the implement to have much more flexibility over irregular terrain.
