Product Details & Features

This 37X57 (037X57MA) cutter deck V‑belt is a reliable replacement belt designed to drive the cutter deck blades on many Murray and compatible ride‑on lawn tractors with a 30″ cutting deck. It ensures smooth and consistent power transfer from the engine pulley to the mower deck pulleys, helping maintain efficient cutting performance and dependable mowing results.

• Deck Drive Application: Designed specifically as a cutter deck belt to power the blades on 30″ deck ride‑on or rear‑engine mowers. 

• Durable V‑Belt Construction: Built to resist normal wear and tear from flexing and engagement, helping reduce slipping and extend belt life.

Why It Matters:
A proper deck belt is essential for your mower’s cutting performance. A worn, stretched or cracked belt can lead to uneven blade speed, slipping, poor cutting quality or even deck disengagement. Replacing it with the correct 37X57 belt restores reliable blade drive, smoother operation and more consistent mowing — helping your tractor stay productive season after season.
