Woods 1050 backhoe to Massey 243 tractor

[Bull Hill Farm]

To prevent damage to the hydraulic draft control mechanism, this mechanism must be locked out when using 3 PT backhoe. Be there Massey nor Woods can supply the product nor can they give me a diagram of the a product that would work to lock out the hydraulic draft control to prevent damage by repeated popping of the relief valve. Attached are the bolt on two plates of half inch steel that I fabricated attaching the tractor differential to the top link hydraulic draft control. Any knowledge as to whether this would work or any suggestions as to the design an application.
