The two hydraulic cylinders which fold the power harrow are synchronised with a small cylinder which automatically lock with hooks the two power harrow wings in the vertical, transport position. Only one lever is required for this operation. When unfolding to the working position, the small cylinder first opens the transport locks, then the main cylinder unfolds the wings. For folding the operation is reversed. The two halves of the power harrow can float independently to follow ground contours
