KEXMY (2) Lawn Mower Blades for Cub Cadet RZT42 XT1-LT42 XT2-LX42 Replaces 942-04308

What It Is

A set of two aftermarket 18-inch mower blades designed for select Cub Cadet zero-turn and lawn tractor models with 42-inch decks. These replace the OEM part 942-04308 and are meant for standard mulching, bagging, or side-discharge cutting.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 42-inch decks (RZT42, XT1-LT42, XT2-LX42). Measure your deck width—if it’s 46” or 54”, these won’t work.
• Model series: Compatible with Cub Cadet XT1 Enduro Series LT42, XT2 LX42, and RZT42 zero-turn. Not for older LT models or non-Cub Cadet brands.
• OEM vs aftermarket: These are aftermarket replacements for OEM part 942-04308. They match the OEM hole pattern (center hole and two offset holes) and overall length (18”). Confirm your existing blade’s length and hole spacing if unsure.

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish. Users report they cut well and hold an edge similar to OEM, but may not last as long in heavy or rocky conditions.
• Installation: Straightforward—remove the blade bolt, swap blades, and torque to 70-80 ft-lbs. No special tools required beyond a socket and wrench. Note the blades are not marked “left” or “right”; both are identical, so orientation doesn’t matter.
• Common gotcha: The sharpened edge is on one side only—these are not reversible. Install with the cutting edge facing the direction of rotation (upward on the right side of the deck). Also, the paint can chip off quickly, but this doesn’t affect performance.
• Price: At ~$16.68 per blade, it’s roughly half the cost of OEM Cub Cadet blades, making it a budget-friendly option for regular replacement.

Should You Buy It

Buy these if you have a Cub Cadet 42-inch deck and want a reliable, cost-effective blade for routine cutting on typical residential lawns. They’re a solid value for the price, but if you mow rough terrain, heavy weeds, or need maximum durability, stick with OEM or a premium aftermarket brand.
