CUB CADET 490-110-F199 Blade Set Fab ZTS1 ZT1 XT2 XT1 LX46 LT46 46 490-110-C199

What It Is

This is a set of three OEM Cub Cadet 46-inch fabricated mower blades designed for zero-turn (ZT1, ZTS1) and lawn tractor (XT1, XT2, LX46, LT46) models with 46-inch fabricated decks. They replace worn or damaged blades to restore cut quality and avoid scalping.

Fitment & Compatibility

• Deck size: 46-inch fabricated deck only (not stamped steel decks).
• Models: Cub Cadet ZT1 46, ZTS1 46, XT1 46, XT2 46, LX46, LT46, and compatible with 490-110-C199.
• OEM vs aftermarket: This is genuine Cub Cadet – direct bolt-on, no mods needed.
• Measurements: Blade length ~18.5 inches, center hole 0.75 inch (with alignment notch), thickness 0.1875 inch. Confirm your existing blade length and hole pattern match before buying.
• What to check: Look for “FAB” on your deck label or measure the blade mounting holes – these will not fit stamped decks or 42-inch/54-inch models.

Key Things to Know

• Quality: Factory OEM steel, thicker than many aftermarket blades – holds edge longer and resists bending.
• Installation difficulty: Easy – remove old blades, note orientation, torque to 70–90 ft-lbs. Use a blade lock or wedge to prevent spinning.
• Common gotchas: Don’t mix with stamped deck blades – they use a different spindle pattern. If you have a 46-inch stamped deck, these won’t fit. Always replace all three at once for balanced cut.
• Sharpening: Not recommended – these are heat-treated and losing temper can cause cracking. Replace when dull or damaged.

Should You Buy It

If you own a 46-inch fabricated deck Cub Cadet ZT1, ZTS1, XT1, XT2, LX46, or LT46 and want a guaranteed fit with OEM durability, this set is the right choice. Skip it if you have a stamped deck or a different deck size – you’ll need the correct blade for your model.
