CUB CADET 490-110-C207 42" Blade Set 05720 XT1 LT42E LT42 Lithium Ion E

What It Is

This is a set of three 42-inch OEM replacement blades (part 490-110-C207) designed specifically for Cub Cadet XT1 LT42E and LT42 Lithium Ion electric riding mowers. It’s a direct OEM replacement for mulching, bagging, or side-discharge cutting.

Fitment & Compatibility

Before buying, confirm your mower deck size is exactly 42 inches (not 46 or 50). This set fits Cub Cadet XT1 LT42E and LT42 models with the 42-inch stamped deck. It is not compatible with gas-powered XT1 models (which use a different blade shape or spindle). Check your owner’s manual or existing blade part number—this replaces OEM 05720, 490-110-C207, and 490-110-0207. Measure your blade length (21 inches per blade) and center hole diameter (1-inch) to verify.

Key Things to Know

• Material quality: These are OEM-grade steel with a heat-treated edge. They hold an edge longer than most aftermarket blades but still dull faster on sandy soil.
• Installation difficulty: Easy—requires a socket wrench and blade removal tool or block of wood to lock the blade. Torque to 40–50 ft-lbs.
• Common gotcha: The blades are slightly thicker than some aftermarket options, so they may not fit if your spindle bolts are worn or deformed. Check spindle condition before install.
• Balance: Pre-balanced from the factory, but always check with a blade balancer before installing to avoid vibration.

Should You Buy It

If you own an XT1 LT42E or LT42 Lithium mower and want a guaranteed fit without modifying spindles or hunting for aftermarket specs, this OEM set is the safe, reliable choice. It’s priced fairly for OEM quality and will give consistent cut performance. Avoid if you have a gas XT1 or a different deck size—those need different blades.
