2022 Bad Boy Revolt 36" Stand-on Zero-Turn mower. It's powered by a 22-HP Kawasaki FX691V V-twin with only 37 hours. The ignition doesn't seem to engage the starter for an unknown reason. Therefor we were unable to start the engine. This mower can't be manually pushed; as if something is locked up in the hydraulic system. The battery will need replacement.
