Original MTD 09164A — Plate‑Reinforcement (09164A‑0637)
Keep your mower deck solid where the blade spindle mounts. This genuine MTD plate‑reinforcement is a stamped reinforcement plate made to strengthen the 91 cm (36") mowing deck around the spindle/adapter area, helping stop cracking or distortion of the deck where the blade hardware bears down.
Fits application notes and example models
This part is used on MTD 91 cm (36") mower decks (Mowing Deck B / MTD009416) and appears on parts diagrams for models such as the TRAC 12‑91 and Spider 91 S (example diagram: 13A1452B600), listed as part 09164A (also shown as 09164A‑0637 in some parts lists). It replaces older 09164 references where shown.
Why this part matters
If the reinforcement ring or plate around your spindle has bent, cracked, or worn thin, the blade adapter, spindle assembly and fasteners won’t seat correctly — leading to vibration, premature wear, or unsafe operation. Installing the correct MTD plate‑reinforcement restores the proper mounting surface so the blade adapter and spindle clamp evenly.
Notes
- Part number shown in some catalogs as 09164A or 09164A‑0637; listed on 36" (91 cm) deck diagrams.
(If your mower’s parts diagram lists a different part number or a different deck size, check that the deck model matches the MTD 36" (91 cm) listings above before ordering.)
