If you pride yourself on having a green thumb, tilling and cultivating is certain to be one of your favorite warm weather activities… but not if your tiller lets you down. When that happens, turn to Repair Clinic and our full inventory of Troy-bilt tiller parts. Keeping your tiller engine tuned-up with a fresh spark plug and air filter is strongly recommended before the tilling season even begins. If the engine runs rough, it’s possible the fuel filter or carburetor is clogged with the residue of old fuel. All of these engine parts are available from Repair Clinic, along with new roto-tiller tines, control cables, drive belts, handles, and more. Enter the full model number of your tiller in Repair Clinic’s search bar for a complete list of parts compatible with your model, including such popular models as the Troy-bilt Horse Garden Tiller and the Big Red Garden Tiller, both powered by a 306cc Briggs and Stratton engine. If you’re having trouble finding the tiller replacement part you need, please contact our Customer Service Team at 1-800-269-2609; they’ll be happy to assist you with your selection and purchase.
