Lawn Mower Parts 539117245 Deck Belt Replacement for Dixon Husqvarna 46" Deck Z246 RZ46 RZ4623 RZ46i RZ4619 RZ4621 LSZ4622 LSZ5422 LSZ5424 RZ4620 RZ5422 RZ5424 Fits for John Deere M118756

What It Is

This is a replacement deck belt for 46-inch zero-turn and lawn tractors, designed to drive the mower blades on Husqvarna, Dixon, and select John Deere models. It matches OEM part numbers 539117245 and M118756.

Fitment & Compatibility

Before buying, verify your mower has a 46-inch cutting deck. This belt fits Husqvarna Z246, RZ46, RZ4623, RZ46i, RZ4619, RZ4621, RZ4620, RZ5422, RZ5424, and Dixon LSZ4622, LSZ5422, LSZ5424. Also fits John Deere models using OEM belt M118756. Measure your old belt—this belt is 3/8-inch wide by approximately 93.5 inches long (common for 46" decks). Check your owner’s manual for your specific model’s belt length; slight variations exist between model years. If your mower has an OEM 539117245 or M118756 belt, this is a direct replacement. Not for 42-inch or 54-inch decks.

Key Things to Buy

• Quality: Aftermarket belt, not genuine OEM. Users report good durability for residential use, but heavy commercial use may wear faster than OEM.
• Installation: Moderate difficulty. You’ll need to remove the deck or use a belt routing diagram (available online). Take a photo of the old belt path before removal.
• Common Gotcha: Deck spindle pulleys must spin freely. A seized pulley can snap a new belt quickly. Check and lubricate spindles before installing.
• Length Verification: If your old belt is 94+ inches (common on some 46" decks), this belt may be too short. Measure carefully.

Should You Buy It

If you have a 46-inch Husqvarna, Dixon, or compatible John Deere zero-turn or lawn tractor and need a reliable, budget-friendly replacement for light-to-moderate mowing, this belt is a solid pick. For heavy commercial use or if you prefer OEM peace of mind, spend more on a genuine Husqvarna belt.
