What It Is

This is a 3-blade replacement set for 46-inch cutting decks, designed for residential lawn tractors. It fits Cub Cadet, Toro, MTD, and Troy-Bilt models requiring OEM part numbers 942-04124, 942-04125, 742-04124, or 742-04125.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches wide (measured blade tip to tip). This set replaces OEM Cub Cadet 942-04124/942-04125 and Toro 742-04124/742-04125. Compatible with popular models like Cub Cadet i1046, LT1045, LT1046, Toro LT series, MTD 46-inch decks, and Troy-Bilt 46-inch decks. Double-check your mower’s model number—not all 46-inch decks use these blades (some use longer or shorter types). Measure existing blade length: these are typically 18 inches long with a 1-inch center hole and 5-point star drive. Avoid buying if your blades have a different hole shape or length.

Key Things to Know

• Quality: These are aftermarket blades, not OEM. They’re made from hardened steel but may not have the same heat treatment or durability as originals. Expect acceptable performance for residential use.
• Installation: Easy, but you’ll need a torque wrench. Tighten blade bolts to 70-90 ft-lbs (check your manual). Use thread locker if recommended.
• Gotcha: The “star” drive pattern can wear over time; ensure the adapter on your spindle matches. If your original blades have a different drive shape, these won’t fit.
• Balance: Aftermarket blades sometimes require balancing—check with a blade balancer before reinstalling. An unbalanced blade causes vibration and cuts unevenly.

Should You Buy It

If you own a Cub Cadet, Toro, MTD, or Troy-Bilt with a 46-inch deck and want a budget-friendly replacement for seasonal residential mowing, this set works. Avoid it if you need OEM-grade durability for heavy commercial use or have a non-standard spindle drive.
