532405143 Deck Belt Fit for Craftsman 46" Riding Mower - Deck Drive Belt Fit for Craftsman Pou LAN HU YTH22V46 YTH2246 YTH20K46 YTH18K46 Lawn Mower with 46" Deck, Replace 584453101 7133156

What It Is

This is a replacement deck drive belt for 46-inch Craftsman riding mowers. It transfers power from the engine pulley to the mower deck spindles, enabling the blades to spin and cut grass. Designed for gas-powered lawn tractors with a 46-inch cutting deck.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be exactly 46 inches (measure deck shell width if unsure).
• Model series: Fits Craftsman POU, LAN, HU, and specific models like YTH22V46, YTH2246, YTH20K46, YTH18K46. Check your mower’s model number (under seat or on frame).
• OEM cross-references: Replaces Craftsman part numbers 584453101 and 7133156. If your mower uses a different OEM number, measure belt length (should be ~96.5 inches) and width (1/2 inch) to confirm fit.

This is an aftermarket belt, not OEM—quality is generally good, but ensure pulley diameter and belt routing match your deck.

Key Things to Know

• Quality: Most users report it works well for regular mowing. Some note slightly less durability than OEM, but acceptable for the price.
• Installation: Moderate difficulty. Requires removing the deck, loosening pulleys, and threading the belt around spindles and tensioner. A diagram or photo of the old belt routing helps.
• Common gotcha: The belt may feel tight initially—check tensioner spring and pulley alignment. If it slips or squeals, re-check routing or replace tensioner pulley.
• No instructions included: Have your mower’s manual or a YouTube video handy for routing.

Should You Buy It

If you need a budget-friendly replacement for a 46-inch Craftsman riding mower and can handle a straightforward installation, this belt is a solid choice. It’s not built for heavy commercial use, but for residential lawns and occasional mowing, it delivers reliable performance at a fraction of OEM cost.
