Deck Belt 574845603 / Kevlar Cord / 5/8" x 143 1/2" - Compatible with Husqvarna GT 52XLS, GT 48XLSI, GTH 2752TF, GTH 24V52LS, GTH 26V52LS, GTH 3052TDF, GTH 3052TF GTH 52XLS TS 352 Series

What It Is

This is a 5/8-inch wide, 143.5-inch long Kevlar-cord reinforced lawn mower deck belt designed to transfer power from the engine pulley to the mower deck spindles on specific Husqvarna zero-turn and lawn tractor models (e.g., GT 52XLS, GTH 2752TF, TS 352 series). It’s a direct replacement for OEM part 574845603.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This belt fits 48-inch and 52-inch decks on the listed Husqvarna models only. Measure your deck width and confirm it matches one of those sizes.
• Model number: Double-check your mower’s exact model number (e.g., GT 52XLS vs. GT 48XLSI) against the list in the title. Husqvarna uses subtle variations that can change belt length.
• Belt dimensions: The belt is 5/8" wide and 143.5" long. Measure your old belt (or the routed path) to confirm these numbers. If your old belt is a different length or width, this won’t fit.
• OEM vs aftermarket: This is an aftermarket belt (not Husqvarna OEM), but it uses Kevlar cord for added strength. It’s a compatible replacement, not a genuine Husqvarna part.

Key Things to Know

• Kevlar cord advantage: Kevlar resists stretching and heat better than standard rubber belts, so this belt should last longer under heavy use or in hot conditions. However, it may be stiffer initially.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt guard, release the tensioner pulley, and route the belt around all deck spindles and the engine pulley. A diagram is recommended—check your manual or online for routing.
• Common gotcha: The 3.3-star rating from 18 reviews suggests some users experienced premature wear or incorrect fitment. Measure carefully; a 143.5" belt is exact—if your deck uses a slightly different length (e.g., 144"), this belt may not tension properly.
• No warranty info: Aftermarket belts often lack the same warranty as OEM parts. Confirm the seller’s return policy before buying.

Should You Buy It

Buy this belt if you have a compatible Husqvarna model (GT 52XLS, GTH 2752TF, TS 352 series, etc.) and want a Kevlar-reinforced option that’s cheaper than OEM. Skip it if your model isn’t listed, you need an exact OEM replacement, or you’re uncomfortable with aftermarket fitment risks—measure your old belt first to avoid returns.
