MTD 11104‑153 — gearbox/shifter arm (11104‑153). Heavy‑duty stamped steel lever that mounts to the gearbox pivot and engages the clutch / shift mechanism; designed to replace a worn, bent or broken arm in gearcases.

Common fitment: this item is the 11104 series arm used in  gearboxes (seen on the  LM5360 ) and the same style lever is found on reel / roller and walk‑behind mowers from makers that fit gearcases — for example  LM5360HXR and comparable Hayter / Mountfield machines.

Key detail for installers: the arm works with the gearbox sleeve/bush hardware used in these gearcases (sleeve listed as φ17×φ21×L15 and mating bush φ15×φ17×L15 in the parts manual), so check those mating dimensions when replacing the arm to ensure correct fit and alignment.

If you keep MTD parts on hand for service, this direct‑replacement 11104‑153 arm is the exact style of gearbox lever you’d reach for when a shifting / clutch arm has failed — robust, serviceable, and ready to reinstall into the gearcase assemblies.
