• 2 longer outer blades from the 742-04125 / 942-04125 family
• 1 shorter center blade from the 742-04124 / 942-04124 family
• 754-04153 / 954-04153 deck belt family
• 756-04129 / 956-04129 idler family
• 756-0627 / 756-0627D idler family
Because Cub Cadet used different 46-inch deck configurations, compare your original OEM numbers before ordering.

Important: This Complete Kit Has More Specific Fitment
Some MTD-built mowers use the same blades and spindle assemblies but use a different deck belt or different idler pulley configuration.
That means compatibility with our 80-KT-002 blade set or 80-DK-010 spindle-and-blade kit does not automatically mean this complete 80-DK-031 kit will fit.
For this kit, verify the belt and both idler pulley families in addition to the blades and spindles.

LT1045 / LT1046 vs. LTX1045 / LTX1046
These are different deck platforms.
This LT-style configuration:
• 3 spindle assemblies
• 3 blades
• 2 longer outer blades + 1 shorter center blade
• 754-04153 / 954-04153 belt family
Common LTX1045 / LTX1046 configuration:
• 2 spindle assemblies
• 2 longer blades
• Different spindle, blade and belt families
Do not order by 46-inch deck size alone.

Don't Need the Belt and Idler Pulleys?
See our 80-DK-010 6-piece deck rebuild kit. It uses the same compatible 3-spindle / 3-blade platform without the deck belt and idler pulleys and therefore covers additional applications that do not use the complete 80-DK-031 belt and idler configuration.
Only Need the Blades?
See our 80-KT-002 3-blade set. Because blade fitment does not depend on the spindle, belt or idler configuration, that set covers a wider range of compatible 46-inch mower decks.
Need Help Confirming Compatibility?
Send us your complete mower model number and, if available, the OEM numbers from your original belt, blades, spindles or idler pulleys. We can help confirm whether this complete kit matches your deck.
