Massey Ferguson 754-04139 Spare Part - Belt A X 72,2

MTD 754-04139 — genuine MTD deck/drive belt (superseded by 954-04139). Heavy‑duty covered V‑belt designed for the cutting‑deck/drive system on a range of walk‑behind and garden tractors. This is the original MTD part number used to transfer power between engine and deck/spindle pulleys.

Key specs you’ll care about for fit and routing:
- Outside length: approximately 72.25 in → ~1,835 mm.
- Width (belt top): 1/2 in → 12.7 mm.
- Construction: covered V/wedge profile with aramid/Kevlar reinforcement for increased wear, heat and shock resistance.

Typical applications: deck drive / spindle belt on a number of MTD and Cub Cadet walk‑behind mowers and related equipment. Example machines that have been listed for this part or its replacement (954‑04139) include Cub Cadet CC760 33" walk‑behind mowers, some MTD WCM 84 series units, and several Craftsman walk‑behind mower model families (for example references such as 12A‑764R299 and related 12A/247 series listings). It’s also referenced as a replacement for certain Massey Ferguson small tractor/implement belts. Confirm routing and length against your machine’s parts diagram before installing.

Notes for installation: replace any belt that shows glazing, cracks, or missing rubber; route exactly per the mower’s deck diagram and check tension and pulley alignment after installation to avoid premature wear. The part has been listed as superseded to 954‑04139 in some parts catalogs — if you see 954‑04139 referenced, it is the later MTD replacement number for the same belt.

If the measurements above match your old belt and the routing fits your machine’s diagram, this belt restores reliable deck drive performance and resistance to abrasion and heat for typical lawn‑mower use.
