YTH22V46 532405143 46" Lawn Mower Deck Belt (1/2"X106") for Husqvarna AYP 584453101,2246LS, 2346XLS, YTH20K46, YTH2146XP, YTH18K46，Ariens 21546607，Craftsman 7133156

What It Is

This is a 46-inch lawn mower deck drive belt, 1/2 inch wide by 106 inches long, that transfers power from the engine pulley to the mower blades on select Husqvarna, AYP, Craftsman, and Ariens riding mowers with a 46-inch cutting deck. It’s a direct replacement for OEM belts on models like the YTH22V46, 2246LS, 2346XLS, YTH20K46, YTH2146XP, YTH18K46, and their equivalents.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch stamped deck and that the belt routing matches your model. This belt cross-references OEM part numbers 532405143 and 584453101 (Husqvarna/AYP), 21546607 (Ariens), and 7133156 (Craftsman). Measure your old belt—it must be 1/2 inch wide and 106 inches long. It will not fit 42-inch or 54-inch decks, nor will it work on zero-turn mowers or older models with different pulley spacing. Check your owner’s manual or the belt routing diagram under the deck for confirmation.

Key Things to Do

• Measure before buying – Even if your model is listed, deck wear or aftermarket pulleys can shift belt length needs. A 106-inch belt is standard, but verify with a tape measure.
• Inspect pulleys and spindles – Worn or seized pulleys will shred a new belt quickly. Spin each spindle by hand; replace any that wobble or drag.
• Installation is moderate – You’ll need a wrench to release the idler pulley tension. No special tools, but routing can be tight. Take a photo of the old belt path first.
• Quality is adequate for residential use – This is an aftermarket belt, not OEM. It’s fine for occasional mowing (1–2 acres/week) but may wear faster under heavy or commercial use.

Should You Buy It

If you have a compatible 46-inch deck Husqvarna, AYP, Craftsman, or Ariens rider and need a budget-friendly replacement for light to moderate residential mowing, this belt works well. For heavy-duty or daily commercial use, consider an OEM belt for longer life. Check your model and measure the old belt first—fitment is narrow, so don’t assume compatibility by brand alone.
