MTD 36098-147 — Grass bag (fabric) designed for rear-bagger Lawnflite / MTD 553-series walk‑behind mowers. This is the replacement cloth collection bag (bag only — frame not included) that slips onto the mower’s rear bagger frame and catches clippings cleanly for easy emptying. Fits Lawnflite / MTD 553 models such as 553HWS, 553HRS and 553HWSP (21‑inch / 53 cm deck examples from mid‑2000s model years). Durable, purpose‑built original MTD design so the shape and mounting collar match the factory bagger frame for a straightforward swap.
