What It Is

This is a replacement drive belt (5/8" wide, 69" long) for the blade engagement or deck drive system on select MTD-built lawn tractors. It connects the engine pulley to the mower deck spindles, enabling blade rotation. Designed for models like the Troy-Bilt Pony, Yard Machines, Cub Cadet, Huskee, White Outdoor, and Columbia—especially the 13AN689G766 and 13AN779G766 series.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This belt fits 42-inch and 46-inch decks on the models listed. Do not assume it works on all deck sizes—measure your old belt if possible.
• OEM cross-reference: Replaces OEM numbers 754-04001, 954-04001, and 954-04001A. Aftermarket versions may vary slightly in material or tension.
• Measurements: Exact dimensions are 5/8" width x 69" length. If your existing belt is shorter or longer, this won’t fit. Check for wear on pulleys—worn or bent pulleys can cause premature belt failure.

Pro tip: Confirm your mower’s model number (e.g., 13AN689G766) under the seat or on the frame. Not all Troy-Bilt Pony or Cub Cadet models use this belt.

Key Things to Know

• Quality variance: At $10.99, this is a budget aftermarket belt. Expect shorter lifespan than OEM—maybe 1-2 seasons vs. 3-4 with a premium brand.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least release tension from the idler pulley. No special tools, but patience helps.
• Common gotcha: Belt may be slightly tight on first install. Run the deck for 5 minutes, then re-check tension. Slipping or squealing means it’s too loose—adjust idler.
• Not for hydrostatic or transmission drive: This belt powers the blades only, not the wheels. Don’t confuse it with the main drive belt.

Should You Buy It

If you need a quick, low-cost fix for a seasonal mower or a backup belt, this is fine. But if you mow heavy grass weekly or want maximum durability, spend a few dollars more on a premium aftermarket or OEM belt—it’ll save you the hassle of early replacement.
