101.5 inches 429636 197253 Deck Drive Mower Belt 42 Inch for Craftsman Husqvarna AYP Poulan 532429636 532197253 598559101 592855001 Fits YTH18542 YTA18542 YTH22V42 YTH20K42 PP19A42/Aramid Cord

What It Is

This is a 42-inch replacement deck drive belt (101.5 inches long) for select Craftsman, Husqvarna, AYP, and Poulan lawn tractors. It transfers power from the engine pulley to the mower deck blades, using aramid cord construction for added durability over standard belts.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 42 inches (measured blade tip to blade tip). This belt fits models like YTH18542, YTA18542, YTH22V42, YTH20K42, and PP19A42. Cross-reference OEM numbers: 429636, 197253, 532429636, 532197253, 598559101, 592855001. Measure your old belt’s length—101.5 inches is critical. Avoid if your deck is 46 or 48 inches; this belt is too short. Also check pulley arrangement: this is for standard 3-blade 42-inch decks with a spring-loaded idler.

Key Things to Buy

• Aramid cord resists stretching and heat better than standard rubber belts, but it’s slightly stiffer—allow a few minutes of run-in for proper seating.
• Installation is easy (no special tools) if you can release the idler pulley tension. Watch a quick video for your specific model—belt routing varies.
• Common gotcha: If the belt is too tight or too loose after install, the idler spring may be worn. Replace it if the belt won’t stay tensioned.
• Not for zero-turn mowers—this is designed for lawn tractors only.

Should You Buy It

If you need a reliable, affordable replacement for a 42-inch Craftsman or Husqvarna tractor deck, this belt is a solid choice. The aramid cord gives it extra longevity over budget belts, and the price is fair. Just double-check your deck size and OEM part number first.
