Youxmoto 42" Deck Spindle 618-0624 918-0659 Fit for MTD/Cub Cadet RZT LT1040 LT1042 17AE2ACG, Fit for Toro LX420 LX425, Replaces 918-0624 (2 PCS)

What It Is

This is a replacement spindle assembly for the 42-inch cutting deck on select MTD, Cub Cadet, and Toro lawn tractors. It houses the blade pulley and bearing, transferring power from the belt to spin the blade. It’s designed for residential mowers with 42" fabricated or stamped decks.

Fitment & Compatibility

Before buying, confirm your deck is 42" and your model is in the list below. Measure the spindle mounting hole pattern – these use a standard 4-bolt pattern with 3.25" center-to-center spacing (check against your old spindle). The housing diameter is about 4.5". This set replaces OEM part numbers 918-0624, 918-0659, and 618-0624. Fits these common models: Cub Cadet RZT LT1040, LT1042, 17AE2ACG; Toro LX420, LX425; also MTD 13A-325-190, 13A-326-190, and many Yard-Man, Troy-Bilt, and Craftsman models with a 42" deck using the same spindle. If your mower uses a different spindle (e.g., stamped steel with a 3-bolt pattern), this won’t fit.

Key Things to Know

• Quality: These are aftermarket spindles. Most buyers report they match OEM build and fit well, but a few note the bearings may wear faster than OEM under heavy use.
• Installation: Moderate difficulty – you’ll need a socket set, a jack to lift the mower, and possibly a puller to remove the old spindle from the deck. Expect 30–60 minutes per spindle.
• Common gotcha: The included hardware may not match every deck’s bolt size – have spare 5/16" or 3/8" bolts on hand. Also, torque the center bolt to 30–40 ft-lbs; overtightening can damage the bearing.
• Two-pack value: Buying as a pair (2 spindles) is often cheaper than buying singles. Replace both at once if one is worn to avoid uneven blade height.

Should You Buy It

This is a solid choice for DIY homeowners with a 42" MTD/Cub Cadet/Toro mower who need a budget-friendly spindle replacement. It’s not for heavy commercial use – if you mow over 2 acres weekly, invest in OEM or higher-end aftermarket spindles. For typical residential lawns, it offers good value and easy fitment.
