Riding Lawn Mower Deck Belt 1/2" x 89 1/4" for Murray 037X88 037X88MA 37X88 37X88MA 710213, Scotts 710213

What It Is

This is a replacement deck belt for riding lawn mowers, specifically sized 1/2 inch wide by 89 1/4 inches long. It drives the mower blades from the engine pulley and is designed for Murray and Scotts models with 42-inch or similar decks that use this belt length.

Fitment & Compatibility

Before buying, confirm three things: First, measure your existing belt length exactly—this belt is 89 1/4 inches, and a mismatch of even 1/2 inch can cause slipping or poor blade engagement. Second, verify your deck size (typically 42-inch decks on compatible Murray/Scotts tractors). Third, check your mower’s model number against the listed OEM numbers: Murray 037X88, 037X88MA, 37X88, 37X88MA, and Scotts 710213. This belt replaces OEM part 710213. It is an aftermarket belt, not genuine OEM, so inspect the pulley grooves for wear before installing—worn pulleys will destroy a new belt quickly.

Key Things to Know

• Quality: Rated 4.4/5 from 31 reviews, suggesting good durability for the price. Expect a standard rubber construction, not Kevlar or heavy-duty.
• Installation: Moderate difficulty. You’ll need to remove the deck or use a belt routing diagram. Release the tensioner pulley to slip the belt on—never force it over sharp edges.
• Common gotcha: The belt may be slightly tight on some decks. If it won’t seat, double-check your measurement and routing path. Also, this belt is not universal—do not assume it fits other brands like John Deere or Craftsman without cross-referencing.
• Tip: Replace the belt in pairs if your deck uses two belts, and always check the tensioner spring and pulley condition at the same time.

Should You Buy It

If you own a Murray or Scotts riding mower that uses a 1/2" x 89 1/4" belt (OEM 710213), this is a solid, affordable replacement. It’s not heavy-duty, but for standard residential mowing, it offers good value and reliable performance. Skip it if you need a reinforced belt for commercial use or if your pulley system is worn.
