Threlaco 2 Pack 42/46" 783-06424A-0637 Red Deck Belt Cover and 954-04060b 954-04060c Deck Belt Compatible with MTD, Craftsman, Troy-Bilt, Mowers, Cub Cadet, Craftsman Lawn Mower Machines

What It Is

This is a two-piece set: a red deck belt cover (replaces OEM 783-06424A-0637) and a 42-inch or 46-inch deck belt (replaces OEM 954-04060b/954-04060c). Designed for residential lawn tractors from MTD, Craftsman, Troy-Bilt, and Cub Cadet that use a stamped steel deck.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size – The belt is for 42-inch or 46-inch decks only. Measure your deck’s cutting width, not the tractor model number.
• OEM part numbers – The belt replaces 954-04060b or 954-04060c. The cover replaces 783-06424A-0637. If your machine uses a different OEM number, this won’t fit.
• Deck type – Fits most MTD-style stamped decks with a single belt routing over two spindles and a tensioner. Not for fabricated decks or zero-turn mowers.

Common compatible models: Cub Cadet LT series, Craftsman LT1000/1500/2000, Troy-Bilt Pony, and MTD Yard Machines. Check your owner’s manual or measure the old belt length (should be ~105 inches for 42-inch, ~115 inches for 46-inch).

Key Things to Know

• Aftermarket quality – Belt is aramid-reinforced rubber, not OEM Kevlar. It will work fine for residential use but may wear faster under heavy mulching or wet grass.
• Installation – Moderate difficulty. You’ll need a socket set to remove the deck, a belt routing diagram (download one), and a pry bar to release tension. The cover snaps on with plastic clips – no tools needed for that part.
• Common gotcha – The cover’s red color fades within one season. That’s cosmetic only, but if you want it to stay bright, skip this set.
• Two-pack value – You get a spare belt, which is smart if you mow over an acre weekly. Belts on these decks typically last 1-2 seasons.

Should You Buy It

Yes, if you have a 42" or 46" MTD-style tractor and want a budget-friendly replacement with a spare belt on hand. Skip it if you need OEM-grade durability for commercial use or if your deck uses a different belt length/cover design. For $24, it’s a solid value for residential mowing.
