918-05016 Spindle Assembly for 918-04825 618-04825 Fit for Cub Cadet 50" Deck LTX1050 LTX1050KH LTX1050VT LTX1050KW SLTX1050 Replaces 618-04825A 618-05016 918-04825A (3 Pack)

What It Is

This is a 3-pack of spindle assemblies for the 50-inch fabricated deck found on Cub Cadet LTX1050 series lawn tractors. Each spindle houses the bearings and shaft that spin the mower blade—replace them when you hear grinding, see wobble, or the blade won’t spin freely.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch fabricated deck (not stamped). This fits Cub Cadet LTX1050, LTX1050KH, LTX1050VT, LTX1050KW, and SLTX1050 models. It replaces OEM part numbers 618-04825A, 618-05016, and 918-04825A. Measure the bolt pattern on your existing spindle—this assembly uses a 4-bolt mounting pattern with 2.5-inch center-to-center spacing. Also verify the shaft diameter matches your blade (typically 1 inch). If your deck is stamped steel or a different size (46", 54", etc.), this will not fit.

Key Things to Know

• Quality vs OEM: These are aftermarket replacements. Most users report they match OEM specs, but a few note slightly looser tolerances on the bearing seals. Grease them before installation.
• Installation difficulty: Moderate. You’ll need a jack, socket set, and a breaker bar for the blade nut. Expect 30–60 minutes per spindle. The hardest part is removing the old, rusted spindle from the deck.
• Common gotcha: The pulley bolt can strip easily if over-torqued. Use a torque wrench set to 30–35 ft-lbs. Also, the included lock washers may be thin—reuse your OEM ones if possible.
• Pack of three: You get all three spindles for one deck. If only one is bad, you can keep the extras as spares, but it’s often smart to replace all at once since bearings wear similarly.

Should You Buy It

Buy this if you have a Cub Cadet LTX1050 series with a 50-inch fabricated deck and need to replace all three spindles at a lower cost than buying OEM individually. It’s a solid value for DIY homeowners who can handle moderate mechanical work. Skip it if you want exact OEM fitment or have a different deck size/model.
