954-04167, 95404167, 754-04167, 75404167 Lawn Mower Timing Belt Compatible with MTD Cub Cadet Lawn Mowers with 42" Timed Decks

What It Is

This is a timing belt (OEM part numbers 954-04167, 754-04167) that synchronizes the twin blades on MTD and Cub Cadet lawn tractors with 42-inch timed decks. It’s used on mowers with a two-blade system where the blades must spin in opposite directions for proper cutting and discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch timed deck (not a standard 42-inch stamped deck). This belt fits select MTD, Cub Cadet, Troy-Bilt, and Craftsman models from the 2000s–2010s with the “Timed” deck system (blades counter-rotate). Check your deck’s model number (stamped on the top or side) and compare to the OEM parts list for 954-04167. Do not rely on brand alone – the same brand may use a different belt for non-timed decks. Measure the belt length: OEM spec is 66.5 inches (outside circumference), 1/2-inch wide. If your old belt is shorter or wider, it’s the wrong part.

Key Things to Know

• Quality: Aftermarket versions are common and usually fine, but some have slightly thinner rubber – inspect for cracks after first season. OEM or high-rated aftermarket is safer.
• Installation difficulty: Moderate. You must remove the deck, release blade brake tension, and route the belt around two pulleys and an idler. A diagram is often printed on the deck. Take pictures before removing the old belt.
• Common gotcha: This belt is not for decks with a single blade or for 46/50/54-inch decks. Also, if your deck has a “Free-Floating” or “Dual-Blade” system (blades spin same direction), this belt won’t work.
• Signs of wear: Squealing, blade timing off (uneven cut), or visible fraying. Replace immediately if belt is glazed or stretched.

Should You Buy It

If you own a 42-inch timed deck MTD/Cub Cadet tractor and need a reliable replacement, this is a solid budget-friendly option. It’s not for non-timed decks or larger mowers, so double-check your deck type first. For the price, it’s a good buy – just expect average aftermarket lifespan (2–3 seasons with normal use).
