The BRIGGS & STRATTON 75-167 Lawn Mower Deck Drive Belt 1/2\" x 95-1/4\" transfers engine power to the mower deck for smooth and efficient blade operation. Designed as a replacement deck drive belt, it fits compatible lawn mowers requiring a 1/2-inch by 95-1/4-inch belt to connect pulley-driven cutting components. It works by maintaining proper tension and rotational movement between pulleys to drive the mower blades during operation. This supports reliable power transmission, reduced belt slippage, consistent cutting performance, and dependable mowing results.
