954-04317A Drive Belt for Cub Cadet, Length 67", Heavy-Duty, Aramid Cord Belt Replaces 954-04317, 754-04317, 754-04317A for Craftsman 247. & Z Series, Troy Bilt Mustang & Z Series, MTD RZT, ZT Series

What It Is

This is a heavy-duty drive belt (67" length, aramid cord construction) for zero-turn mowers, specifically designed to transfer power from the engine to the hydrostatic pumps or deck spindles on select Cub Cadet, Craftsman, Troy Bilt, and MTD models. It’s built for residential use with occasional heavy cutting.

Fitment & Compatibility

Before buying, confirm your mower’s deck size and model series:

• Fits: Cub Cadet RZT, Z-Force, Z-Series; Craftsman 247. & Z Series; Troy Bilt Mustang & Z Series; MTD RZT, ZT Series.
• Check OEM part numbers: Replaces 954-04317, 754-04317, 754-04317A. Verify your old belt’s part number or cross-reference with your mower’s manual.
• Measure your old belt: Lay it flat and measure end-to-end. It must be exactly 67" (not 66" or 68"). If it’s stretched, measure a new belt of the same length for accuracy.
• Belt width: Typically 1/2" or 5/8". Measure the width of your old belt or the pulley groove. A 67" belt in the wrong width will slip or rub.

Key Things to Know

• Aramid cord = longer life, stiffer feel. This belt resists stretching and heat better than standard rubber belts, but it may feel slightly tighter during installation. That’s normal.
• Installation tip: Use a 1/2" drive breaker bar or socket wrench to relieve tension on the idler pulley. Never pry the belt over pulleys with a screwdriver—it can damage the cord.
• Common gotcha: Some ZT models route this belt around a spring-loaded idler. Note the exact belt path before removing the old one. Take a photo.
• Not for decks over 54" on most models—larger decks often require a different length (e.g., 68" or 72").

Should You Buy It

If you own a Cub Cadet, Craftsman, Troy Bilt, or MTD zero-turn with a 42"–54" deck and need a durable belt that won’t snap mid-season, this is a solid upgrade over generic rubber belts. It’s not for push mowers, tractors with manual transmissions, or decks requiring a shorter/longer belt. For the price, it’s a reliable OEM replacement that outlasts most store-brand options.
