754-04219 954-04219 Mower Deck Belt for Cub Cadet LTX 1045 LTX 1046 Troy Bilt Horse XP Bronco MTD Craftsman T1600 T140 46 Inch Deck CMXGZAM501009 OCC-754-04219 | Aramid Cord | 1/2" x 103"

What It Is

This is a 46-inch mower deck drive belt (1/2" x 103") for select Cub Cadet, Troy-Bilt, MTD, and Craftsman lawn tractors with a 46-inch fabricated or stamped deck. It transfers power from the engine pulley to the spindle blades—essential for cutting.

Fitment & Compatibility

Measure your existing belt – This belt is 1/2" wide and 103" long. Verify both dimensions; a wrong length means poor tension or slipping.

Check your model number – Fits Cub Cadet LTX 1045, LTX 1046, Troy-Bilt Horse XP, Bronco, MTD models, and Craftsman T1600, T140 with a 46-inch deck. Also listed as compatible with OEM #754-04219, 954-04219, and CMXGZAM501009.

Deck type matters – This belt is for 46-inch fabricated or stamped decks, not 42-inch or 50-inch. Confirm deck size on your machine’s sticker.

Aftermarket note – This is an aftermarket replacement made with aramid cord (stronger than standard rubber). It should match OEM specs but may wear differently on older pulleys.

What to check before buying:

• Deck size (measure blade tip to tip across the deck)
• Current belt part number
• Pulley condition (worn or rusty pulleys will shred any belt)

Key Things to Know

• Quality – Aramid cord construction is tougher than standard rubber belts, offering longer life in dusty or heavy-use conditions. Expect less stretch over time.
• Installation – Moderate difficulty. You’ll need to remove the deck or at least the belt guard. A belt tensioner tool or socket helps. Allow 30–60 minutes.
• Common gotcha – This belt can be tight on some decks. If it’s too stiff to slip over the last pulley, double-check you have the correct routing diagram. Many online videos show the exact path for 46-inch MTD decks.
• Warranty – Aftermarket belts usually have limited warranty (often 90 days). OEM belts may last longer but cost more. This belt is a value pick.

Should You Buy It

If you need a reliable, budget-friendly replacement for a 46-inch deck belt on a Cub Cadet, Troy-Bilt, MTD, or Craftsman tractor, this aramid cord belt is a solid choice. It’s tougher than standard rubber but requires careful installation and good pulley condition. Skip it if you want an OEM belt for a warranty claim or if your pulleys are worn.
