Abstract

A folding tool bar apparatus for a farm implement or the like having a horizontally disposed main frame and a pair of wing sections pivotally attached at each end thereof to the main frame. Gauge wheels are attached to each of the wing sections for spacing a wing section a predetermined distance from the ground when the wing section is in use. A rigid link member is pivotally attached to each of the wing sections. Hydraulic cylinders are pivotally attached to the main frame and to the link members. These hydraulic cylinders have a first elongated position which permit the wing members to be in a substantially horizontally extended working position and a second shortened position for causing the wing members to be in a substantially folded transport position. Adequate clearance is provided among the hydraulic cylinders, rigid link members, main frame and wing members for permitting the wing members to pivot upwardly and downwardly from the aforesaid horizontally disposed main frame when the hydraulic cylinders are in the extended position thereof for allowing the wing members to pivot upwardly and downwardly from the horizontal position to accommodate unevenness in the ground being traversed by the respective wing section.
