587270001 Z242F Lawn Mower Deck Belt Made with Kevlar for Husqvarna 42" Decks 967953803 967271802

What It Is

The 587270001 is a Kevlar-reinforced drive belt for 42-inch cutting decks on Husqvarna Z242F zero-turn mowers and compatible models. It transfers power from the engine pulley to the deck spindles, enabling blade rotation for mowing.

Fitment & Compatibility

• Deck size: 42 inches only. Do not use on 46", 48", or 54" decks.
• Exact models: Husqvarna Z242F (967953803, 967271802). Also fits some Husqvarna YTH, LTH, and GTH garden tractors with 42" decks (check your model number).
• Measurements: 1/2 inch wide, 105.6 inches effective length. Measure your old belt end-to-end (not looped) to confirm.
• OEM equivalent: Replaces Husqvarna OEM part 587270001. Aftermarket versions may vary in length by ±0.5" – verify fit before installing.

Key Things to Know

• Kevlar construction resists stretching and heat better than standard rubber belts, extending life in dusty or heavy-use conditions.
• Installation difficulty: Moderate. You’ll need to remove the deck, release belt tension (spring-loaded idler), and route around three spindles and two idler pulleys. Check your manual for the routing diagram.
• Common gotcha: The belt can flip if routed incorrectly under the idler pulley. Confirm the belt’s rib side faces the pulleys and the flat side rides on the flat idler.
• Break-in period: New belts may slip or squeal for the first 15–30 minutes. Retension after initial use if needed.

Should You Buy It

If you own a Husqvarna Z242F with a 42" deck and want a durable, OEM-spec belt that resists stretching and heat, this is a solid choice. It’s a direct, drop-in replacement for the factory belt and works well for residential or light commercial mowing. Skip it if your deck is a different size or you need a cheaper generic alternative.
