Husqvarna 539109243 Replacement: Compare 8 Options

How to find your model number

Check your model number before you buy a replacement for the 539109243. On a riding mower or lawn tractor the model and serial label is usually under the seat, on the frame beside the seat, or near the battery. Deck parts may also need the deck size, which is often on a decal on top of the deck.

If the old belt is still readable, the part number is often printed on its back. To measure it, run a cloth tape along the outside of the belt and note its width.

Spring maintenance

Check the deck belt before the first cut: replace it if it is cracked, frayed, glazed or slipping on the pulleys. Look over the idler pulleys at the same time.

• Maker's own part: made and sold by the equipment or engine maker (for example John Deere, MTD or Briggs & Stratton). Usually the highest price.
• Aftermarket parts: made by other companies to the same size and fit. Usually cheaper; materials and build quality vary by brand.
• Before you buy: find your equipment's model number (see How to find your model number, above), compare the size of your old part, and confirm the fit on the product page.
