Husqvarna LC221FHE 21 in 163 cc 4-Stroke Walk-Behind Mower with Electric Start and Mulching Capability HIGH VIBRATION Error Fix: Excessive Vibration

The mower vibrates abnormally during operation — the most likely cause is a bent blade (from hitting a rock, root, or stump) or a bent crankshaft; a bent blade is the single most common cause of abnormal walk-behind mower vibration; remove and inspect the blade or spin it on the crankshaft to check for wobble; a loose blade bolt also causes vibration; an unbalanced blade after sharpening vibrates at high RPM; use a blade balancer after sharpening
