If you count on your MTD tiller to help keep your garden the envy of the neighborhood, you can count on Repair Clinic to help keep your tiller in peak condition. We stock all the parts to maintain and fix MTD tillers, including popular models like the MTD Gold 21A-39M8704A. Before the gardening season even starts, you should tune-up the tiller engine by replacing the spark plug and the air filter. If old fuel residue has clogged the carburetor or fuel filter, you should consider replacing those components as well to ensure optimum engine performance. If the fuel tank has become damaged, Repair Clinic carries the replacement tank, fuel lines, and fuel cap that match your model. Need a new bail arm or handle? We have those as well, along with tiller tines, control cables, and drive chains. Just type the full model number of your MTD tiller into our website’s search bar for a list of compatible parts. If you’re unable to locate the right part, please call our Customer Service Team at 1-800-269-2609 for further assistance.
If you need help installing that new part, be sure to explore Repair Clinic’s unmatched collection of “step-by- step” videos, diagrams, articles, and schematics for guidance. In less time than you think, your MTD tiller will be ready to cultivate that garden.
