Lawn Mower Deck Belt Compatible with Husqvarna 574845602 YTH24V48LS & YTH2648 GT48XLS TS348 YT48XLS

What It Is

This is a replacement deck belt (OEM part #574845602) for select Husqvarna lawn tractors and zero-turn mowers. It drives the mower blades via the engine pulley, enabling cutting deck operation.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., YTH24V48LS, YTH2648, GT48XLS, TS348, YT48XLS). This belt fits 48-inch cutting decks on these Husqvarna models. Measure your old belt’s length (usually 96.5 inches) and width (1/2 inch). This is an OEM Husqvarna belt, so it matches original specs. Check your deck’s belt routing diagram (often under the seat or in the manual) to confirm it matches the 3-pulley system. Not compatible with 42-inch or 54-inch decks.

Key Things to Know

• Quality: OEM construction with reinforced rubber; longer lifespan than generic aftermarket belts.
• Installation difficulty: Moderate – requires removing deck or using a spring tool to release tension. Watch for sharp edges on pulleys.
• Common gotchas: Incorrect routing causes blade imbalance or belt slippage. Ensure belt is fully seated in all pulley grooves. If the old belt snapped, inspect pulleys for damage or debris.
• Price: $29.99 is competitive for OEM; aftermarket belts may be cheaper but often wear faster.

Should You Buy It

Yes if you own one of the listed Husqvarna 48-inch deck models and want a direct-fit, reliable replacement. It’s ideal for DIY owners who prefer OEM quality over cheaper alternatives. Skip if your deck size or model isn’t listed, or if you’re comfortable with aftermarket belts for occasional use.
