954-04044A Lawn Mower 50" Deck Belt 1/2"x134" for Troy Bilt Cub Cadet MTD RZT 754-04044 954-04044 754-04044A RZT22 RZT50

What It Is

This is a 1/2-inch wide, 134-inch long A-section V-belt designed to drive the cutting blades on 50-inch deck zero-turn mowers from Troy-Bilt, Cub Cadet, and MTD. It replaces OEM part numbers 754-04044, 954-04044, 754-04044A, and 954-04044A.

Fitment & Compatibility

• Deck size: Only for 50-inch decks (not 42", 46", 54", etc.).
• Models: Fits Troy-Bilt RZT22, RZT50; Cub Cadet RZT22, RZT50; and select MTD Z-Force models with a 50" fabricated deck. Always confirm your model number on the mower’s ID tag.
• OEM vs aftermarket: This is a Cub Cadet branded belt, not a generic. It matches OEM specs – no guesswork on length or width.
• Measurement check: 1/2" width x 134" outside length. If your old belt is stretched or broken, measure the belt path (around all pulleys) to confirm 134" is correct. A 1/2" belt will not fit a 3/8" pulley groove.

Key Things to Know

• Quality: Users report it lasts 1–2 seasons with normal residential use. Not reinforced for heavy commercial duty.
• Installation: Moderate difficulty – you’ll need to remove the deck or at least the belt covers. A belt routing diagram is usually printed on the deck; take a photo before removing the old belt.
• Common gotcha: The belt can chirp if tension is too low. Check the idler pulley spring is not rusted or weak. Replace any seized pulleys at the same time.
• Storage: Remove tension when storing the mower over winter to prevent belt memory-set and premature failure.

Should You Buy It

If you own a Troy-Bilt or Cub Cadet zero-turn with a 50-inch deck and need a direct OEM replacement without measuring or cross-referencing aftermarket belts, this is a safe, reliable choice. It’s not for commercial mowing, but for residential lawn care it offers solid value at this price point.
