DR Mower Parts carries blade adapters for all makes and models of lawn mowers. The blade adapter attaches the lawn mower blade to the engine shaft. Blade adapters are made to shear if the mower hits a rock or solid object so the engine shaft doesn't get bent. Blade adapters may also need to be replaced if worn out. Blade adapters are specific to your make and model of lawn mower so please contact us if not sure which one to purchase.
