TENGMUJX spindle assembly 618-06980 / 918-06980 is a direct-fit replacement kit for 50-inch mower decks, supplied here as a three-pack to service multiple spindles quickly.

If your zero-turn or riding mower is using a 50" cutting deck and shows symptoms like uneven cutting, unusual vibration, or blade wobble, replacing worn spindles is a common repair. These TENGMUJX spindles are engineered to match the OEM mounting pattern for many Cub Cadet, Troy-Bilt, Craftsman and related models, letting you restore deck performance without sourcing factory units. The kit focuses on fit, durability, and straightforward installation so you can get back to mowing with minimal downtime.

Will this spindle fit my 50-inch Cub Cadet or Troy-Bilt deck?

Yes — the assembly is built to replace OEM part numbers MTD Cub Cadet 618-06980 and 918-06980 used on many 50" decks. Check your mower model and deck specifications against the compatibility list before ordering to confirm a match.

• Compatible with models like XT1-50, GT50, ZT1-50, RZT-L50 and similar 50" decks.
• Also fits various Troy-Bilt Super Bronco/Mustang 50-inch and Craftsman G8200/G8300 applications.
• Matches the four-threaded mounting bolt pattern used by the OEM units.

How difficult is installation for a homeowner mechanic?

Installation is designed to be manageable for someone with basic tools and mechanical experience. The spindle uses four threaded mounting bolts and straightforward connections to the deck and blades, so you can replace it at home in an afternoon with common shop tools.

• Remove the blade and pulley, unbolt the old spindle from the deck.
• Position the new spindle, align mounting holes, and torque bolts to spec.
• Reinstall pulley and blade, then test for smooth rotation and proper blade clearance.

What performance and durability should I expect from these spindles?

The assemblies are manufactured to meet the same mounting dimensions and operational function as the OEM spindles, with materials chosen for lawn-application durability. They offer reliable rotation and support for 50" blades, reducing vibration and improving cut consistency when installed correctly.
