An improved farm implement of the foldable, sectional tow type including a central section, including a wheeled cart and wing sections hingedly connected to the central section. Each of the wing sections is comprised of a plurality of hingedly connected frames to allow good ground coverage on abrupt terrain. The sections are further connected to the cart for movement between transport positions and cultivating positions and a lock is provided between the various frames of the wing section and operable to preclude the same from oscillating relative to each other when in the transport position.
