Mower Deck Belt 429636 197253 / Aramid Cord / 101.20 inches/for Husqvarna Craftsman Poulan AYP 429636 592855001 598559101 532429636 YTH18542 YTA18542 YTH22V42 YTH20K42

What It Is

This is a 101.20-inch Aramid cord-reinforced mower deck belt designed to drive the blades on select Husqvarna, Craftsman, Poulan, and AYP riding mowers with 42-inch or 46-inch cutting decks. It replaces OEM part numbers 429636, 592855001, 598559101, and 532429636, and fits models like the YTH18542, YTA18542, YTH22V42, and YTH20K42.

Fitment & Compatibility

Before buying, verify these three things:

1. Deck size: This belt is for 42-inch and 46-inch decks only. Measure your deck or check the model number sticker under the seat or on the frame.
2. OEM cross-reference: Confirm your original part number matches 429636, 592855001, 598559101, or 532429636. If you have a different number, this belt likely won’t fit.
3. Belt length: The exact length is 101.20 inches. Measure your old belt (lay it flat, measure end to end) to be sure—a ½-inch difference can cause slipping or poor engagement.

Brand note: This is an aftermarket belt, not OEM Craftsman/Husqvarna. It’s built to the same specs but may have slightly different cord material (Aramid vs. Kevlar). It fits any mower that originally used the OEM part numbers listed.

Key Things to Know

• Aramid cord is strong and heat-resistant—good for heavy use or thick grass, but not as flexible as Kevlar in cold weather. Expect a slightly stiffer feel during installation.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt guard, and you may need a ½-inch socket or wrench to release the tensioner pulley. Watch a model-specific video for routing.
• Common gotcha: This belt is directional. The part number should face outward. If it flips, it can slip off the pulleys. Also, check your idler pulleys and spindles for wear—a bad pulley will shred a new belt fast.
• Price vs. OEM: At $13.85, it’s roughly half the cost of an OEM belt. You sacrifice some brand warranty, but for most homeowners, the value is solid.

Should You Buy It

Buy it if you need a reliable, budget-friendly replacement for a 42-inch or 46-inch deck on a Husqvarna, Craftsman, Poulan, or AYP rider and you’re comfortable with a moderate DIY install. Skip it if you need an exact OEM match for warranty purposes, or if your mower has a non-standard deck size or unusual pulley setup—measure twice first.
