Aeagle LT50 Spindle Assembly for 50-inch Decks, 3-Pack — OEM Fit, 6.5" Pulley & 6-Point Star

The Aeagle LT50 Spindle Assembly 3-pack is a direct-fit replacement spindle kit designed to restore cutting performance on 50-inch decks used by select Cub Cadet, Troy-Bilt, MTD and related tractors.

If your 50" mower deck is wobbling, making noise, or leaving an uneven cut, a worn spindle is often the cause. This Aeagle kit includes three full spindle assemblies engineered to match the original equipment specifications (6-point star, 6 3/16" height, 6.5" pulley outer diameter) and fits the serial numbers and model families listed by the manufacturers. The result is easier installation and a return to consistent blade alignment and belt tracking without modifying the deck.

How do I know this spindle fits my mower?

Compatibility depends on the exact model and serial ranges. The Aeagle LT50 spindle replaces OEM part numbers used across MTD, Cub Cadet and Troy-Bilt 50" decks and is intended for specific model years noted by the manufacturers.

• Replaces OEM 618-06981, 918-06981, 82-106, 285-710.
• Fits Cub Cadet XT1-LT50 and XT2-LX50 (select 2015–2016 models) with 50" decks.
• Compatible with MTD/Columbia CYT5023SE (2015–2019) and Craftsman T260 (2019–2021) where listed.
• Works with Troy-Bilt TB2350/Bronco 50 series tractors referenced in the serial lists.

What are the physical and performance specifications?

This spindle assembly matches the original geometry to preserve blade position and belt alignment. It uses the same 6-point star mounting and pulley diameter so blades spin true and belts remain in correct track.

• Overall spindle height: 6 3/16" (158 mm) for proper deck clearance.
• Pulley outer diameter: 6.5" to maintain factory belt routing and tension.
• 6-point star bolt pattern for direct bolt-on replacement.
• Sold as a pack of three assemblies for complete deck service or spares.

How difficult is installation and what should I expect?

Installation is straightforward for someone comfortable with basic mower maintenance; you’ll need common hand tools and a safe way to support the deck. Because the spindle matches OEM dimensions, no modifications to the deck or belt path are normally required.

• Remove deck, blades, and old spindle using socket set and torque wrench.
• Install new spindle with manufacturer-specified torque on mounting bolts.
• Reinstall blades and belts, check belt alignment and blade runout.
• Test cut at low speed to confirm smooth operation and no unusual vibration.

Will using this spindle change my mower’s warranty or performance?

These are aftermarket replacement spindles built to OEM dimensions to return original performance. They are intended for repair and maintenance use; check your mower’s warranty terms for third-party parts policies.

• Designed to restore factory blade height and belt tracking when installed correctly.
• Use alongside proper maintenance—sharp blades, correct belt tension—for best results.
• Confirm serial numbers and fitment before purchase to avoid installation issues.

Who is this for: The Aeagle LT50 Spindle Assembly 3-pack is aimed at homeowners, landscapers, and repair shops maintaining 50-inch deck lawn tractors from Cub Cadet, Troy-Bilt, Craftsman and MTD models listed in the fitment notes.
