Description

This is a Genuine OEM Ace part. Basic InformationPart Name: Lawn Mower Drive BeltManufacturer: Briggs & StrattonCategory: Lawn MowerPrimary Function: Transfers power from the engine to the cutting bladesInstallation & CompatibilityCompatible Models:Fits 42-inch cut mowers, including models from 2009 2010 such as PB195H42LT, PB2042YT, and XT195H42LTCompatible with Craftsman model 917.289610Compatible with Husqvarna models LTH2042 and YTH2042Installation Difficulty: Medium; requires basic mechanical skills and familiarity with your lawn mowerTools Required: Wrench set, screwdrivers Additional Information: The Briggs & Stratton Lawn Mower Drive Belt (part number 230-0643) connects the engine to the blades on 42-inch cut mowers, keeping them turning at the correct speed for consistent cutting. It replaces worn or broken belts that can cause blade slowdown, inconsistent mowing, or loss of drive power. If your engine runs but the blades don t spin, or if your mower leaves patches of uncut grass, replacing the belt may fix the issue. Installing a new drive belt helps restore cutting performance and prevents extra wear on other mower components. To install, disconnect the spark plug wire and wait for the mower to cool. Use a wrench and screwdrivers to remove guards and covers. Follow the belt routing diagram in your mower s service manual to guide installation. Make sure the belt is properly tensioned and that all safety components are reattached before use. | Ace Lawn Mower Replacement Drive Belt, 101-1/2 In X 1/2 In 230-0643 Genuine OEM
