Abstract
Abstract A foldable sectional tow-type implement, including a wheel cart having a centrally located section which is revolvably mounted on a horizontal axis extending transversely of the direction of travel for movement between a lower, generally horizontal, operative position and a generally vertical transport position, and a pair of outboard sections interconnected to the centrally located section and each being revolvable with the center section and also swingable in a fore and aft direction relative to the center section when revolved to the vertical transport position to permit folding of the outboard sections rearwardly relative to the center section. Each of the sections support or mount agricultural type tools. At least portions of each of the outboard sections are offset forwardly of the centrally located section to provide bypass clearance for the tools when the outboard sections are folded rearwardly and also to shift the center of gravity of the entire implement forwardly to facilitate revolving the sections to the vertical transport position. Wheels for all of the sections are mounted on a common horizontal axis forward of the sections. Flexible cables are connected between the outboard sections and the end of a swingable arm pivoted to the cart forward of the sections. The arm is locked in a lowered position to support the outboard sections when the implement is in its operative position. The arm is released for swinging to a rearward position to permit the outboard sections to be folded rearwardly, but the cables remain connected to the arm and outboard sections whereby the outboard sections pull the arm rearwardly during folding. An independent positive lock, hydraulically actuated when the outboard sections are lowered to their operative positions, is provided to lock the cable arm in its lowered position. The outboard sections are hingedly connected to the center section with a lost motion structure to provide for limited vertical movement of the outboard sections relative to the center section about the hinge connections to accommodate irregular terrain when the implement is moved thereover while in its folded transport position.

Claim 1
Independent Claim
284 words
In a mobile foldable sectional agricultural type implement which includes a mobile cart for travel over the ground in a forward direction, said cart being adapted for connection to a prime mover and including a frame having tool carrying means, said frame being mounted on the cart and extending transversely of the direction of travel and being revolvable about an axis transversely of the direction of travel for movement between a generally horizontal operative position and a generally vertical inoperative or transport position, said frame having a central section and a pair of end sections, the end sections being hinged to the central section for swinging movement relative to the central section to a rearward folded position in angular relation to the central section when the frame is in said vertical transport position, and power means on said cart for revolving said frame about said axis to permit folding said end sections, the improvement comprising means hingedly connecting said central section to each end section with the end sections and the ground engaging tools carried thereby being offset forwardly of said central section and the corresponding ground engaging tools carried thereby so that when said end sections are folded about said hinge means, ground engaging tools on said end sections will be vertically displaced from the ground engaging tools on said central section to preclude interfering contact therebetween, and support means on each section for ground engaging wheels, each extending forwardly distances to locate each wheel center forwardly of said axis when said sections are in said horizontal operative positions, said forwardly located sections placing the center of gravity of the frame closer to said axis for lessening the pressure on said power means.
