CUB CADET 954-04317A Transmission Drive Belt A X 67 Z Force RZT LX SX SZ ZT1 ZT2

What It Is

This is a genuine OEM transmission drive belt (part number 954-04317A, size A x 67 inches) for Cub Cadet Z Force, RZT, LX, SX, SZ, ZT1, and ZT2 zero-turn mowers. It transfers power from the engine to the hydrostatic transmissions, enabling forward and reverse movement.

Fitment & Compatibility

• Check your model number – This belt fits specific Cub Cadet zero-turn series listed above, but not all models within those lines. Verify your mower’s model number (found under the seat or on the frame) against the OEM parts list.
• Deck size does not determine this belt – It’s for the transmission, not the deck drive. Deck size (e.g., 42", 50", 54") is irrelevant for fitment.
• OEM vs aftermarket – This is a genuine Cub Cadet belt. Aftermarket belts (e.g., Stens, Oregon) may be cheaper but often vary in length or material quality. Use OEM for guaranteed fit.
• Measure your old belt – If possible, confirm length (67 inches) and cross-section (A-section, 1/2" wide). A mismatched length can cause slippage or damage.

Key Things to Know

• Installation difficulty – Moderate. You’ll need to remove the deck and possibly the mower’s floor pan or fender deck for access. Allow 1–2 hours.
• Belt routing – Snap a photo of the old belt before removal. Routing is specific and easy to get wrong on zero-turn transmissions.
• Check pulleys – While replacing, inspect transmission pulleys for wear, wobble, or debris. A worn pulley will quickly destroy a new belt.
• Tension and break-in – The belt will stretch slightly during the first few hours. Recheck tension after 5 hours of use and adjust if your model has an adjustable idler pulley.

Should You Buy It

If you own a compatible Cub Cadet zero-turn and need a reliable, OEM-spec transmission belt, this is a solid choice. It’s priced fairly for a genuine part and has strong user reviews. Skip it if you want a cheaper aftermarket alternative or if your mower uses a different belt length.
