Compatibility：The 4113746 lift spring / wheel lift spring is compatible with Ryan LA‑4 / LA‑5 (new style with folding handle), Lawnaire IV/V lawn aerators, and also compatible with Bobcat AE19 and AE26 aerators replacement part
Material：Made from heat-treated high-carbon steel with zinc-plated surface, suitable for repeated mechanical stress and outdoor operation. Free length is 6.1 inches—please confirm your old spring's free length and end style (hook, loop, or eyelet) before purchasing
Replacement：If you experience stiff or jerky lift handle movement, inconsistent aeration depth, unbalanced lifting, or a front end that no longer stays raised. A stretched, worn, or broken 4113746 spring can cause these issues
Working Principle：Functions as a counter-tension spring with a spring rate of 4, storing and releasing energy during lift cycles to support balanced motion of the wheel lift mechanism
Installation：The 4113746 extension spring is used in the wheel lift system of lawn aerators and features dual hook-end connections. It's recommended to replace both springs at the same time to maintain even lift tension
