What It Is

This is a Kevlar-reinforced drive belt (5/8" wide, 134" long) that transfers power from the engine to the mower deck blades on select Cub Cadet, MTD, Troy-Bilt, and Toro lawn tractors. It’s designed for heavy-duty mowing on larger properties.

Fitment & Compatibility

• Measure first: Confirm your old belt is 5/8" wide and 134" long. A 1/16" difference can cause slipping or poor engagement.
• Models: Fits Cub Cadet LT1050, LTX1050, LGT1050, LGTX1050; Toro GT2100, GT2200, LX500, SL500. Also replaces OEM part numbers 754-04077, 954-04077A, 112-0332.
• Deck size: Typically for 50" or 54" decks, but always check your mower’s deck size in the manual.
• OEM vs aftermarket: This is an OEM replacement from Cub Cadet, not a generic. It matches factory specs exactly.

Key Things to Know

• Kevlar cord: More durable than standard rubber belts; resists stretching and heat better under heavy loads.
• Installation difficulty: Moderate. You’ll need to remove the deck or access the belt routing under the tractor. A belt routing diagram is essential—snap a photo before removing the old belt.
• Common gotcha: If the old belt broke, check the pulleys and spindles for damage or debris. A new belt on a bad pulley will fail quickly.
• Not for blades: This is the deck drive belt, not the PTO or engine belt. Double-check your mower’s belt routing to confirm.

Should You Buy It

If you own one of the listed Cub Cadet or Toro tractors with a 50–54" deck and want a reliable OEM replacement that won’t stretch or snap mid-mow, this belt is a solid investment. It’s ideal for heavy users who mow large lawns and prefer durability over lower-cost generic belts.
