429636 197253 Lawn Mower Deck Drive Belt 42" Drive Belt 102" x 1/2" Replacement for Husqvarna AYP Poulan 197253 532197253 532429636 John-Deer M84136 M87323 Fits Husqvarna YT1942 YTH2042

What It Is

This is a 102-inch long, 1/2-inch wide deck drive belt designed for 42-inch cutting decks on select Husqvarna, AYP, Poulan, and John Deere lawn tractors. It transfers power from the engine pulley to the mower deck spindles, enabling blade rotation.

Fitment & Compatibility

Must check before buying:

• Deck size: Only fits 42-inch decks (not 46" or 48").
• Exact OEM part numbers: 532197253, 532429636, 197253, M84136, M87323.
• Belt dimensions: 102 inches long x 1/2 inch wide. Measure your old belt end-to-end (flat) and width to confirm.
• Common models: Husqvarna YT1942, YTH2042; Poulan Pro PP42T; John Deere D100/D110/D130 series. Not compatible with zero-turn mowers or older 1/2" x 96" belts.
• OEM vs aftermarket: This is an OEM Husqvarna belt, which often lasts longer than generics. Cross-reference with your mower’s model number (e.g., YTH2042) to be safe.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the deck, loosen tensioner pulley, and route the belt around all three spindles and the tensioner. No special tools required, but a second set of hands helps.
• Common gotcha: The belt must be routed under the tensioner pulley and over the stationary pulleys. Routing it wrong causes slipping or premature wear.
• Quality: OEM-grade construction with Kevlar-reinforced cords. Expect 2-3 seasons under normal residential use if kept clean and dry.
• Warranty: 90-day Husqvarna warranty covers defects but not wear from debris or misalignment.

Should You Buy It

Yes, if you need a direct OEM replacement for a 42-inch deck on Husqvarna, AYP, Poulan, or John Deere models listed above. It’s a reliable, correctly sized belt at a fair price. Skip it if your deck is 46" or larger, or if you prefer a cheaper generic—but expect shorter life.
