Husqvarna LC221FHE 21 in 163 cc 4-Stroke Walk-Behind Mower with Electric Start and Mulching Capability HEIGHT ADJUST STUCK Error Fix: Height Adjuster Jammed

Error code HEIGHT ADJUST STUCK on the Husqvarna LC221FHE 21 in 163 cc 4-Stroke Walk-Behind Mower with Electric Start and Mulching Capability means: Height Adjuster Jammed. The deck height adjustment lever is stuck or will not move between positions — the adjustment mechanism can rust, especially in humid storage conditions; debris can pack around the adjustment brackets; lubricate the pivot points on the height adjustment levers with penetrating oil; some Husqvarna walk-behind mowers have a single-lever multi-point adjustment (one lever adjusts all four wheels simultaneously) — if the linkage is bent, it will bind; check all four wheel height brackets for rust or damage
