Murray Transmission Belt - 037X87MA

Product Details & Features

Keep your lawn tractor’s drive system working smoothly with this Murray Transmission Belt – Part No. 37X87. This high-quality V-belt is designed to replace the original transmission drive belt on a wide range of Murray and compatible lawn tractors, helping deliver reliable power transfer from the engine to the wheels or transaxle. 

The 37X87 transmission belt is a robust V-belt with a ½″ (12.7 mm) width and approximately 97″ outside circumference (2463 mm), engineered to withstand normal lawn tractor operating conditions. It’s used as the main drive belt on selected Murray riding mowers and tractors — transferring engine power smoothly and efficiently to the gearbox or transmission. 

Key Features:

• Reliable Power Transmission: Designed to drive the transmission on compatible Murray lawn tractors, helping ensure smooth movement and traction. 

• Durable V-Belt Construction: Made with quality rubber and reinforcement materials to resist wear, flexing and slippage. 

• OEM Equivalent: Direct replacement for Murray part numbers 37X87, 037X87 and 710341, and many compatible equivalents from Rover, Stihl, Viking and Victa. 

• Widely Compatible: Fits a broad range of Murray lawn tractors with 30″ to 46″ cutting decks, including gear-drive and some hydrostatic models from the late 1990s through the 2000s. 

• Easy to Install: Designed as a direct swap with your original belt — just follow the mower’s belt routing diagram during replacement. 

Why It Matters:
A worn or stretched transmission belt can lead to poor traction, slipping, reduced mower speed or no drive at all. Replacing it with this 37X87 V-belt restores effective power delivery from the engine to the drive system, helping your mower start, move and operate as intended.
