PetMigo 2-Pack Deck Spindle Assembly for 46" Mower Decks — 6-1/2" Pulley, OEM Fit

These two PetMigo deck spindle assemblies replace 918-04865A / 618-04636A for 46" mower decks and include a 6-1/2" pulley OD for direct swap on compatible Cub Cadet, MTD, Troy-Bilt and Craftsman models.

If your mower’s deck is wobbling, making noise, or failing to spin the blade reliably, a worn spindle assembly is often the cause. The PetMigo replacement pair is engineered to match OEM dimensions—6 13/16" height and 6-1/2" pulley outer diameter—so you can restore blade alignment and cutting performance without modifying the deck. These spindles are sold in a two-pack to replace both left and right sides or keep a spare for the next season.

Which mower models will these spindle assemblies fit?

PetMigo spindles are manufactured to fit a wide range of residential riding mowers from major brands when the pulley OD and mounting pattern match. They are compatible with specific Cub Cadet LTX and Z-Force models, MTD/ Craftsman LT series machines, certain Troy-Bilt models, and other listed OEM part cross-references.

• Cub Cadet: LTX-1042, LTX1045, LTX1046, LTX1046VT, LTX1046KW, LTX1046M, Z-Force S 46
• MTD/Craftsman: LT2000, LT2200, LT2500, Z530 and Yard Man SV600-3225
• Troy-Bilt/Other: TB2246, Thoroughbred, Horse, Horse XP, YT4622SE, YT946KH
• Cross-references: 618-04636, 618-04636A, 618-04865, 618-04865A, 918-04636, 918-04636A, 918-04865A

How do these replacements compare to original equipment parts?

PetMigo spindles are designed to duplicate the OEM fit and function so installation uses the same mounting holes, shaft orientation, and pulley size. Materials and machining tolerances aim to match the original geometry to maintain blade balance and deck clearance.

• Exact pulley outer diameter: 6-1/2" to match belt and deck alignment
• Overall height: 6 13/16" for correct blade-to-deck spacing
• Sold as a pair to ensure matched blade heights and consistent cutting

What should I check before ordering and installing?

Verify the part numbers or measure the existing spindle pulley diameter and overall height. Confirm bolt pattern and shaft size match your mower deck; replacing both spindles at once prevents uneven cutting if one spindle is significantly more worn than the other.

• Compare part numbers: 618-04636 / 618-04865 / 918-04865A and cross-referenced OEM codes
• Measure pulley OD (should be 6-1/2") and assembly height (6 13/16")
• Keep hardware and belts on hand; inspect blades for balance after installation

How long will these spindle assemblies last and what warranty is provided?

Service life depends on use, mowing conditions, and maintenance; proper installation and avoiding impacts extend longevity. PetMigo backs these spindle assemblies with a 1-year warranty against manufacturing defects to give buyers added confidence.

• 1-year limited warranty for defects in materials and workmanship
• Inspect for damage after impacts or heavy-duty use to prevent premature failure
• Regularly check mounting hardware and pulleys for wear to prolong service life

Who is this for: homeowners and small-property landscapers who need a reliable, OEM-compatible spindle replacement for 46" riding mower decks. If you operate Cub Cadet LTX models, MTD or Craftsman LT series machines, or similar Troy-Bilt and Yard Man machines and you need a direct-fit spindle with a 6-1/2" pulley, this two-pack provides matched parts for a balanced deck and a ready spare to keep your mower cutting cleanly.
