Built for Real Farm Work

This lock fits Ford Super Q cabs found on various models from the 70s and 80s, Case IH CX and MX series tractors ranging from 50-120 HP, and David Brown models including the 1194, 1294, 1394, 1494, and 1690. These are serious working tractors used for everything from loader work to heavy cultivation, and they need cab doors that stay secure when the going gets rough.

Made to Last

Farm life is tough on equipment, and door locks get plenty of abuse from constant use, dust, and vibration. This replacement uses hardened steel components at the critical wear points, addressing the common failure areas that cause original locks to stick or fail. The mechanism is calibrated to provide positive latching without requiring excessive force to close the door.

Installation Notes

Installation typically takes 45-60 minutes and varies slightly between brands—Ford Super Q cabs usually require inner door panel removal, while Case IH models might need the armrest removed first. Take a photo of the linkage routing before removal to make reassembly easier. Clean and lubricate the door hinges while you have access, and check door alignment—a sagging door puts extra stress on the lock mechanism.
