Abstract
A farm implement having rotatable wings rotatably connected to a main carrier and also having a folding bar linkage, which folds as the corresponding wing is rotated into a stowed position and extends as the wing rotates into a deployed position. A fixed length control bar rotatably linking a tow bar of the folding bar linkage to the main carrier controls the folding and unfolding of the bar linkage as the wing rotates between the deployed and stowed positions.
