Abstract: The present invention provides a farm gate stop device suitable for use on both level and unlevel terrain and reduces strain on the hinges of a gate. The farm gate stop device comprises a rod slide operably attached to a gate and a rod slidably connected to the rod slide. The rod slide has a plurality of notches in cooperation with a stud integral with the rod. The rod slide also has at least one rod guide which keeps the rod in a proper vertical alignment with the rod slide. The rod may be slidably adjusted within the at least one rod guide to hold the gate at which time the stud is moved into the notches of the rod slide to maintain the gate in a desired position.
