We carry replacement parts, repair parts and accessories for 36 MTD Leaf Blower models
Leaf blowers by trusted brands such as MTD clear away organic debris in record time, but even the most reliable leaf blower can develop problems with excessive vibration. Some amount of vibration is normal, but if your leaf blower shakes more than it used to or is uncomfortable to hold, troubleshoot the problem with these tips for common causes.
The fan blade, also called the impeller, draws air into the leaf blower. If the impeller is damaged, loose or has a lodged object, the leaf blower may vibrate excessively and the air output may be weak. Inspect the fan blade, dislodging any stuck objects and tightening the bolt. If you find chips, cracks or damage, replace the impeller with the correct leaf blower parts for your model.
A great deal of leaf blower troubleshooting can be accomplished with a proper tune-up, especially if the blower shakes and the engine runs rough. Empty stale gas and refill the tank. Consult your user manual for the proper ratio of gas-to-oil; most models require one liter of gas to 25 milliliters of oil. Replace the fuel filter to ensure smooth acceleration, and clean the spark plug to prevent stalls. Clean the air filter — a dirty filter restricts air flow.
Over time, the carburetor may shake itself loose or clog with old fuel. If your leaf blower vibrates excessively and the engine sputters, try cleaning the carburetor, or better yet, rebuild or replace it. If the blower only vibrates excessively during idling, adjust the idle set screw according to the manufacturer's recommendations.
