Primary Belt Note: Do not assume every mower using this rebuild kit also uses primary belt 148763. Some compatible AYP deck configurations use a different primary belt. Verify your complete mower model before ordering the additional primary belt.

Does This Kit Fit My Mower?

This kit may fit your mower even if your exact tractor model number is not listed above. AYP manufactured similar mower deck systems for multiple brands and model series over many years.

If your 46" three-blade mower deck requires the following component combination, this is the rebuild kit to compare:

Your mower may also require a separate primary mower deck belt. That does not prevent this rebuild kit from fitting the secondary deck system. Match the components above to the parts required by your deck.

Why Matching the Complete Deck Configuration Matters

AYP manufactured mower platforms and deck components used across several brands, including Craftsman, Sears, Husqvarna, Poulan, Poulan Pro and Roper. As a result, machines sold under different brand names may use the same deck components.

However, sharing only one component — such as the 144959 belt or 143651 spindle — does not automatically mean the complete 80-DK-007 rebuild kit fits. Some 44", 46" and 50" AYP decks share individual components while using different blade lengths, spindle pulleys or deck configurations.

For best fitment accuracy, compare the complete spindle + blade + pulley + idler + secondary belt combination with your original deck parts.
