Yard Machines snowblowers are built on MTD platforms — reliable single-stage and two-stage machines that handle driveways and light commercial snow work. When your Yard Machines won't start, throws weak, or makes noise, the fix is usually one of these common parts. Repair Clinic carries OEM Yard Machines parts that match your exact model, so you get the right fit the first time.
Winter storms don't wait — keep your snowblower ready with seasonal maintenance and the parts that actually fail. A shear bolt is a $2 consumable that saves your auger; a carburetor kit solves 80% of hard-start problems; and a belt replacement restores full throwing power. Order now and get back to clearing.
Yard Machines is the value-tier MTD brand (sold at Walmart and Home Depot), while Yard Man and others are mid-tier MTD products. All share the same core MTD engineering and many parts cross-reference. The key is your model number — enter it to confirm the exact part fit. MTD-family brands often use interchangeable belts, shear pins, and carburetors, but control cables and deck-specific parts vary.
Shear bolts are safety devices designed to break if the auger hits a rock or ice chunk — they protect the transmission and engine. Always replace both auger shear bolts at the same time, even if only one broke, so wear and stress are balanced. Keep a 5-pack of replacements in your snowblower kit. Shear bolt size (usually 3/8" or 1/2") matters — verify your model.
Ethanol in gasoline breaks down over months of storage and clogs the carburetor jet and float. A carburetor kit (includes gasket, float, needle, and jets) fixes 90% of hard-start or no-start problems. If the carb kit doesn't work, try a new spark plug and verify the fuel line isn't cracked. Always drain fuel before long storage or run the engine dry.
Model numbers are stamped on the frame or printed on a label near the engine or fuel tank. They're typically 5 to 7 digits (e.g., 31AE765H002). Enter it in the Repair Clinic model lookup to see the correct parts for your machine — belt width, shear bolt size, carburetor type, and all sub-assemblies will match exactly.
