490-110-C204 Xtreme Blade Set 50"" Decks Ultima ZT1-50 Zero-Turn Mowers，Replacement for CUB Cadet OEM

What It Is

This is a set of three high-lift blades designed specifically for 50-inch cutting decks on Cub Cadet Ultima ZT1-50 zero-turn mowers. They replace the OEM Cub Cadet blades (part #490-110-C204) and are intended for heavy-duty grass cutting, mulching, and bagging on large residential or commercial properties.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Only fits 50-inch decks. Measure your deck width to be sure—this set won’t work on 42-inch or 54-inch decks.
• Model compatibility: Designed for Cub Cadet Ultima ZT1-50 zero-turn mowers. Will also fit other Cub Cadet models with a 50-inch deck that use the OEM 490-110-C204 blade. Check your owner’s manual or current blade part number.
• OEM vs aftermarket: This is a direct OEM replacement, not a universal blade. The center hole, spindle pattern, and blade length (approx. 20.5 inches each) match the factory specs. No adapters or modifications needed.
• Measurements: Each blade is about 2.75 inches wide and 0.25 inches thick. Verify your old blade’s dimensions if you’re unsure.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and a blade removal tool (or a block of wood to prevent spinning). Takes about 15 minutes for all three blades. Torque to 70-90 ft-lbs.
• Quality: High-lift design improves grass discharge and bagging performance, but it may wear faster on sandy or rocky terrain. Expect 25-50 hours of life depending on conditions.
• Common gotchas: Always replace all three blades at once to maintain balance. Don’t overtighten—stripped spindles are a common mistake. Check blade rotation direction (usually counter-clockwise from the operator’s position).
• Price vs OEM: At $140.66, this is typically the same or slightly less than the Cub Cadet branded set. The 5.0 rating is based on only 2 reviews, so treat it as a solid option, not a proven crowd favorite.

Should You Buy It

Buy if you own a Cub Cadet Ultima ZT1-50 and need a direct OEM replacement blade set that delivers strong lift and clean cuts. Avoid if you have a non-Cub Cadet mower or a different deck size—fitment is tight. For the price and rating, it’s a reliable choice for routine blade swaps.
