What It Is

This is a complete spindle rebuild kit for 46-inch cutting decks on select Cub Cadet, MTD, and Troy Bilt lawn tractors. It includes two spindle assemblies (918-04865), two idler pulleys (753-08171), two blades (942-04244), and a 103-inch drive belt (954-04219)—everything needed to refresh the deck’s cutting system in one purchase.

Fitment & Compatibility

• Deck size: Only fits 46-inch stamped or fabricated decks. Measure your deck width before buying.
• Models: Direct fit for Cub Cadet LTX1045, LTX1046, MTD LT2000, LT2200, and Troy Bilt Horse XP. Also works with many other MTD-built 46-inch decks (check your model number against the OEM spindle part 918-04865).
• OEM vs aftermarket: This is an OEM-style replacement, not a genuine Cub Cadet part. Confirm your original spindle part number matches 918-04865. The blades (942-04244) are 17.25 inches long with a 5-point star center hole—measure your old blades.
• Belt length: The 103-inch belt (954-04219) must match your deck’s belt routing. Count your deck’s belt length or check your manual.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic tools (socket set, wrenches, jack stands). Plan 1–2 hours if you’re handy; longer if you’re new to deck work.
• Quality: The spindles and idlers are solid aftermarket replacements. The blades are standard-grade steel—fine for residential use but not for heavy commercial cutting. The belt is a standard cogged V-belt; replace it with a Kevlar-reinforced one if you mow tough terrain.
• Common gotchas: The idler pulley bolts may be rusted or seized—soak with penetrating oil beforehand. The spindle nuts require a torque wrench (specs usually 35–45 ft-lbs). Don’t reuse old lock washers.
• Included vs separate: The kit bundles everything, but you may need separate spindle housing gaskets (not included) if your deck uses them.

Should You Buy It

Buy this kit if your 46-inch Cub Cadet, MTD, or Troy Bilt deck has worn spindles (wobbling, noisy, or leaking grease) and you want a single, cost-effective refresh. It’s ideal for residential mowing and DIY replacement—skip it if you need heavy-duty blades or a genuine OEM warranty.
