CUB CADET 490-110-F202 42" Xtreme Blade Set S-Shaped Mount Lithium Ion Fab 42 ZTS1 ZT1 XT2 XT1 LX42 LT42E CMXGZAM110202

What It Is

This is a set of three 42-inch fabricated steel blades for Cub Cadet Xtreme-series mowers. Designed for use on zero-turn and lawn tractors with a 42-inch cutting deck, the S-shaped edge and lithium-ion coating improve lift and reduce clogging in heavy grass.

Fitment & Compatibility

Before buying, check two things:

1. Deck size – Your mower must have a 42-inch cutting deck. This set is not for 46-inch or 50-inch decks.
2. Model series – Confirmed compatible with:
   • Cub Cadet ZTS1, ZT1, XT2, XT1
   • LX42, LT42E, CMXGZAM110202
   • Also fits some older 42-inch Cub Cadet zero-turns and tractors (Ultima, Pro Z, RZT series – verify blade length and center hole diameter).

Measurement check: Each blade is approximately 14.5 inches long, 2.5 inches wide, with a 5/8-inch center hole. Measure your current blade length and hole size before ordering.

OEM vs aftermarket: This is an OEM Cub Cadet part (490-110-F202), so fitment is guaranteed if your machine is listed. Aftermarket alternatives exist but often lack the S-shape design or lithium-ion coating.

Key Things to Know

• Quality – Fabricated steel (not stamped) is thicker and lasts longer than standard stamped blades, but can be heavier and may require a more powerful engine for optimal performance.
• Installation difficulty – Moderate. You’ll need a torque wrench (recommended 70–90 ft-lbs) and a 15/16-inch socket. The S-shape can make alignment tricky – mark blade orientation before removal.
• Common gotcha – The lithium-ion coating reduces rust but does not make the blade “self-sharpening.” Resharpen every 25 hours of use.
• Performance – The S-shape improves mulching and bagging in tall, wet grass but may reduce discharge speed in dry, thin lawns.

Should You Buy It

Buy this if you have a 42-inch Cub Cadet Xtreme-series mower and frequently cut thick, damp grass where clogging is an issue. The fabricated steel and coating justify the price for heavy-duty use. Skip it if your deck is a different size or you only mow a small, dry lawn – standard stamped blades will work fine and cost less.
