What It Is

This is a complete 46-inch deck rebuild kit for select Cub Cadet and Troy-Bilt zero-turn mowers. It includes two spindle assemblies (part #618-05078/918-05078) and two blades (part #742-04244), designed to replace worn or damaged cutting decks on residential/commercial use.

Fitment & Compatibility

• Deck size: 46” only. Measure your deck width—this will not fit 42” or 50” decks.
• Models: Cub Cadet RZT-L46 KH, RZT-S46, Z6400, ZT-S46 KH; Troy-Bilt Mustang 46 XP. Check your mower’s model number tag under the seat or frame.
• OEM vs aftermarket: Aeagle is an aftermarket brand. Spindles and blades match OEM dimensions but may vary slightly in material or finish.
• Before buying: Verify your existing spindles are the same bolt pattern (typically 3-hole, 5.5” center-to-center). Measure blade length (should be 18” for 46” decks) and center hole size (usually 1” or 5/8”). Confirm your deck uses two spindles (not three).

Key Things to Know

• Quality: 4.1 stars from 11 reviews—generally solid for the price, but some users report spindle bearings wearing faster than OEM.
• Installation difficulty: Moderate. Requires removing the deck, unbolting old spindles, and transferring pulleys. Basic hand tools and a torque wrench needed.
• Common gotchas: Spindle bolts may be reverse-threaded on some decks—check before forcing. Blades may need balancing after install. The kit does not include pulley bolts or washers.
• Warranty: Check seller’s return policy; Aeagle typically offers 30-day coverage.

Should You Buy It

If you need a budget-friendly, complete deck refresh for a compatible 46” Cub Cadet or Troy-Bilt zero-turn, this kit saves you the hassle of sourcing parts separately. It’s best for DIY homeowners with moderate mechanical skills. Skip it if you want OEM durability for heavy commercial use—invest in genuine Cub Cadet spindles instead.
