YTH22V46 Deck Belt 1/2" X106" Made with Kevlar for Husqvarna 584453101 532405143 7133156 2246LS 2346XLS YTH20K46 YTH2146XP and YTH2246, Craftsman 7133156 with 46" Deck

What It Is

This is a 1/2" wide by 106" long deck belt reinforced with Kevlar, designed to drive the blades on 46" cutting decks for Husqvarna and Craftsman lawn tractors. It’s an aftermarket replacement for OEM part numbers 584453101, 532405143, and 7133156.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck and requires a 1/2" x 106" belt. This belt fits specific Husqvarna models (YTH22V46, YTH20K46, YTH2146XP, YTH2246, 2246LS, 2346XLS) and Craftsman models with a 46" deck using OEM 7133156. It’s an aftermarket part, not OEM, so it may differ slightly in material or stiffness. Measure your old belt length (lay flat, measure end-to-end) and width; if it’s 106" x 1/2", this will work. Always double-check your mower’s model number and deck size—belt routing can vary by year.

Key Things to Know

• Kevlar reinforcement improves durability under heavy loads or debris, but it may be stiffer than OEM belts, making installation slightly harder.
• Installation difficulty is moderate—you’ll need to release the deck belt tensioner and route the belt around pulleys. A diagram in your manual helps.
• Common gotcha: This belt is for the deck blades only, not the drive or transmission belt. Verify you’re replacing the correct belt.
• Break-in period: New belts may stretch slightly; check tension after the first hour of use and adjust if needed.

Should You Buy It

If you need a budget-friendly replacement for a worn 46" deck belt on a compatible Husqvarna or Craftsman tractor and want extra durability from Kevlar, this is a solid choice. It’s not a perfect OEM match, but for the price, it’s reliable for typical residential mowing. Skip it if you need an exact OEM fit or have a different deck size.
