Briggs & Stratton V‑Motion Drive Belt – 037X65MA

Product Details & Features

Keep your lawn tractor moving smoothly with this genuine Briggs & Stratton V‑Motion drive belt (037X65MA) — a high‑quality replacement belt designed to transfer engine power to the transmission on select ride‑on mowers and rear‑engine riders. It’s an essential wear item that ensures reliable propulsion and consistent performance season after season. 

This 037X65MA covered V‑belt features a ½″ (12.7 mm) width and approximately 30″ (30.18″ / 766 mm) outside circumference, making it ideal for use as a motion drive belt that links the engine pulley to the transaxle on many Briggs & Stratton‑equipped machines. The durable construction helps resist stretch, slippage and wear for dependable power transfer. 

Key Features:

• Genuine OEM Belt: Designed and manufactured to Briggs & Stratton original equipment standards for proper fit and reliable operation. 

• Drive & Motion Application: Ideal as a motion/transmission drive belt on compatible ride‑on lawn tractors and rear engine riders, helping provide smooth movement and traction.

• Durable Construction: Wrapped V‑belt design resists wear and flex fatigue, improving belt life and reducing the need for frequent replacements. 

• Standard Size: ½″ top width and ~30″ length (outside circumference) for correct tension and alignment in equipment that specifies part 037X65MA / 37X65MA. 

• Direct Replacement: Replaces original numbers 37X65MA, 037X65MA and equivalents — simply route it according to your mower’s belt diagram. 

Why It Matters:
A worn, stretched or cracked drive belt can lead to poor motion performance, belt slipping, grinding noises or loss of propulsion on your mower. Installing a fresh 037X65MA V‑belt restores proper engagement between engine and transmission, helping your equipment start, move and mow reliably.
