Fourtry Spindle Assembly for 46" Mower Deck — 918-04865A Pre-Greased, Greasable Replacement for Cub Cadet LTX1045 LTX1046

The Fourtry 918-04865A spindle assembly is a pre-greased, serviceable replacement spindle engineered to fit 46-inch mower decks on Cub Cadet, Craftsman, Troy-Bilt and many MTD riding tractors.

If your lawn tractor’s deck is wobbling, making unusual noises, or failing to cut evenly, replacing a worn spindle often restores smooth blade rotation and deck performance. This Fourtry spindle is manufactured as an OEM-equivalent part for numbers 918-04865A, 618-04636, 918-04636 and variants, and ships pre-lubricated with a grease fitting so you can maintain it for longer life. It’s designed to match common mounting dimensions and simplifies installation with included hardware.

Which machines will this spindle assembly fit?

This spindle is built to be compatible with many 46-inch decks from popular brands. It matches the mounting and dimensional patterns used on several Cub Cadet LTX models, select Craftsman tractors, Troy-Bilt Thoroughbred units, and a broad range of MTD/MTD-powered riders and zero-turns produced after 2011.

• Compatible models listed include Cub Cadet LTX1045, LTX1046, LTX1042, LT1500, LT2000, LT2200, LT2500 and XT-2 series.

How easy is installation and what hardware is included?

The spindle comes ready for a straightforward swap: threaded mounting holes match common deck patterns and the spindle’s star-shaped top aligns with blade adapters. Fourtry includes key accessories to reduce trips to the parts store so you can get the deck back in service quickly.

• Includes grease zerk and plastic dust cap for the grease port to keep contaminants out.
• Ships with four threaded mounting screws for securing the spindle to the deck.
• Pre-greased bearing surface reduces initial break-in time and simplifies first startup.

• Overall height approximately 6-8/9" and spindle diameter about 6-1/2".
• Mounting hole spacing measured at roughly 5" to align with many 46" decks.
