954-0349 Drive Belt for Cub Cadet MTD 754-0349 1/2" x 79" Mower Belt for Toro 112-0317 for Cub Cadet 754-0640 954-0640 fits Troy Bilt Super Bronco 46" LX460 GT2300 / Aramid Cord/ 1/2 x 79 inch

What It Is

This is a 1/2" x 79" drive belt (part #954-0349) that transfers power from the engine pulley to the mower deck spindles on select Cub Cadet, MTD, Troy-Bilt, and Toro lawn tractors. It’s designed for 46-inch cutting decks on models like the Cub Cadet LX460, GT2300, and Troy-Bilt Super Bronco.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be 46 inches (not 42" or 50").
• Belt dimensions: 1/2" width x 79" length. Measure your old belt if possible—a 1/2" x 79" is standard, but some decks use 1/2" x 78.5".
• OEM cross-references: Fits Cub Cadet 754-0349, 754-0640, 954-0640; MTD 754-0349; Toro 112-0317. Check your mower’s manual or existing part number.
• Brand note: This is an aftermarket belt (not genuine Cub Cadet OEM), but it meets OEM specs. Avoid if your mower requires a Kevlar or reinforced OEM-only belt for heavy commercial use.

Key Things to Know

• Construction: Aramid cord (similar to Kevlar) provides good strength and heat resistance for residential mowing. Not for zero-turn or high-hour commercial use.
• Installation: Moderate difficulty. You’ll need to remove the deck, release belt tension (spring-loaded idler), and route around pulleys. Take a photo before removing the old belt.
• Common gotcha: Some users report the belt is slightly shorter or longer than OEM—measure your deck’s center-to-center pulley distance if possible. If it’s too tight, the belt may squeal or wear pulleys; if too loose, it will slip.
• Durability: Expect 2-3 seasons with normal use (1-2 acres weekly). Replace if you see fraying, glazing, or cracking.

Should You Buy It

Buy this belt if you have a Cub Cadet, Troy-Bilt, or MTD 46" lawn tractor used for residential mowing and want a reliable, budget-friendly replacement that matches OEM specs. Skip it if you need a genuine Cub Cadet part for warranty requirements or if you mow commercially—invest in a heavier-duty OEM or Kevlar belt instead.
