MTD/Troy-Bilt OEM Belt 954-04070A Mtd Troy Bilt Genuine OEM Belt Gw 9245

What It Is

This is a Genuine OEM (Original Equipment Manufacturer) replacement drive belt for MTD and Troy-Bilt lawn tractors and zero-turn mowers, part number 954-04070A (also cross-referenced as GW-9245). It connects the engine pulley to the transmission, transferring power to the wheels.

Fitment & Compatibility

• Check your model number: This belt fits hundreds of MTD/Troy-Bilt models (e.g., 13A-326-000, 13A-329-000, 13AN77BS099), but not all. Look for the model number on a sticker under the seat or on the frame.
• Deck size: Commonly used on 42-inch and 46-inch decks, but verify your specific deck size—belt length and width (typically 1/2" x 92-5/8") must match.
• OEM vs aftermarket: This is an OEM belt, meaning exact fit and spec. Aftermarket belts (e.g., Oregon) may be cheaper but can vary in width or material, potentially slipping or wearing faster.
• Measure your old belt: If you can’t find the model number, measure the old belt length (end-to-end) and width. This belt is about 92.6 inches long and 1/2 inch wide.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the mower deck or access the belt path under the tractor. A belt routing diagram is often printed on the deck or in the manual—take a photo before removing the old belt.
• Quality: Genuine OEM means Kevlar-reinforced construction, which handles heat and tension better than generic belts. Expect 2-3 seasons of normal use.
• Common gotchas: The belt can be tight to install—use a wrench to relieve tension on the idler pulley. Do not pry with a screwdriver; you can damage the belt or pulley. Also, check the idler pulley bearings; if they’re worn, replace them to prevent premature belt wear.
• Return policy: OEM parts are often non-returnable once installed, so double-check compatibility before buying.

Should You Buy It

Buy this if you want a guaranteed fit and long life for your MTD/Troy-Bilt lawn tractor. It’s ideal for owners who prefer OEM reliability over aftermarket savings. If you have an off-brand mower or a very old model, measure your old belt first—otherwise, this is a safe, high-rated choice.
