Ariens Ariens IKON X 52 in. 23 HP Kawasaki FR691V Zero-Turn Mower MECH-BELT Error Fix: Deck Belt Slipping or Breaking

The mower deck belt squeals, slips, or has broken. Deck belts wear over time and can be damaged by debris, misaligned pulleys, or excessive heat. Inspect the belt for cracks, fraying, glazing, or chunks missing. Replace the belt if any wear is found. Check all idler pulleys for smooth, free spinning — a seized idler pulley will destroy a belt quickly. Verify the belt routing matches the Ariens belt routing diagram — an incorrectly routed belt will come off. Remove grass buildup from under the deck and around pulleys.
