954-04060C Mower Deck Belt for Troy Bilt Pony Bronco 42 Inch Cub Cadet LTX1040 LTX1042 MTD Craftsman T110 T1000 T1400 Replace 954-04060B 754-04060B 754-05056 John Deere GX10851 Aramid Cord 1/2 x 96.5

What It Is

This is a 1/2-inch wide, 96.5-inch long Aramid cord-reinforced mower deck belt. It drives the blades on 42-inch cutting decks for Troy-Bilt Pony/Bronco, Cub Cadet LTX1040/LTX1042, Craftsman T110/T1000/T1400, MTD, and select John Deere models.

Fitment & Compatibility

• Deck size: 42-inch only. Do not use on 46-inch or 54-inch decks.
• OEM replacements: Fits 954-04060B, 754-04060B, 754-05056, and John Deere GX10851.
• Measure before buying: Confirm your old belt is 1/2 inch wide and 96.5 inches long (measure outer circumference). Troy-Bilt Pony/Bronco models from 2005–2020 and Cub Cadet LTX1040/LTX1042 (2010–2020) are common fits.
• Check deck spindle layout: This belt routes around three spindles and two idler pulleys. Verify your deck uses a “B” deck or stamped steel 42-inch deck (not fabricated or fabricated “X” deck).
• Brand note: This is a Cub Cadet-branded aftermarket belt, not OEM. It fits MTD-built decks on Craftsman, Troy-Bilt, and Cub Cadet. John Deere compatibility is limited to select 42-inch decks using GX10851 (e.g., D100 series).

Key Things to Know

• Aramid cord vs. Kevlar: Aramid is heat- and abrasion-resistant, similar to Kevlar. It lasts longer than standard rubber belts but costs slightly more.
• Installation difficulty: Moderate. You’ll need to remove the deck, release tension from the idler pulley, and route the belt around spindles. Take a photo of the old belt routing first.
• Common gotcha: Some users report the belt is slightly shorter than OEM (96.3” vs. 96.5”). If your deck tensioner is near max adjustment, this may not fit. Measure your old belt or check deck tensioner arm travel.
• Break-in period: Expect slight stretching in the first 2–3 hours. Recheck tension after mowing one lawn.

Should You Buy It

Buy this if you have a 42-inch MTD-built deck (Troy-Bilt, Cub Cadet, Craftsman) and want a durable aftermarket belt at a lower price than OEM. Skip it if you need a precise OEM fit for a John Deere or an older model with a tight tensioner—measure first to avoid return hassle.
