Murray Lawn Mower Blade Drive Belt – 37x74, Fits 30-inch Cut Decks (125/76, 120/78, 125-76cm)

Need a new blade drive belt for your Murray mower?

This is the 37x74 size, which fits a bunch of Murray models with a 30-inch cut deck, like the 125/76, 120/78, and 125-76cm.

It’s a rubber belt, brand new.

The manufacturer part number is Mu37x74, also listed as 37x74, 37x74mu, etc.

It’s made by PIX or an equivalent brand—solid quality.

This belt drives the blades, so if it’s worn or broken, your mower won’t cut.

Swapping it out gets you back to a clean, even cut.

Simple replacement part.

Check your old belt size to make sure it’s the 37x74, and you’re good to go.
