942-04125 & 942-04124 Lawn Mower Blades Kit for 46" Deck, Compatible with Cub Cad et i1046 LT1045 LT1046 Toro MTD Troy-Bilt, Replaces 742-04124, 742-04125, 742-0612, 942-0612, 3 Pack

What It Is

This is a 3-pack of 46-inch deck mower blades designed to replace worn or dull blades on select Cub Cadet, Toro, MTD, and Troy-Bilt riding mowers. It’s intended for standard residential cutting on medium-to-large lawns.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck (measure from blade tip to blade tip across the deck). This kit fits models like the Cub Cadet i1046, LT1045, LT1046, and similar Toro, MTD, and Troy-Bilt riders. It replaces OEM part numbers 742-04124, 742-04125, 742-0612, and 942-0612. Check your current blade’s length, center hole diameter (typically 1-inch), and thickness—these blades are 20.5 inches long, 2.75 inches wide, with a 1-inch center hole and 0.25-inch thickness. If your deck uses a different spindle or blade pattern (e.g., 42-inch or 50-inch), this kit will not fit.

Key Things to Know

• Quality: Aftermarket blades—generally sharp out of the box but may need light balancing before installation. A blade balancer is cheap insurance against vibration.
• Installation: Easy swap with a socket wrench and blade removal tool. Always disconnect the spark plug wire first. Torque blade bolts to 40–50 ft-lbs (check your manual).
• Common gotcha: These are straight/standard blades, not high-lift or mulching blades. If you need bagging or mulching performance, consider a different design.
• Price vs. OEM: At ~$23 for a 3-pack, it’s significantly cheaper than OEM replacements. Expect slightly shorter lifespan than OEM steel, but fine for typical seasonal use.

Should You Buy It

If you have a 46-inch deck Cub Cadet, Toro, MTD, or Troy-Bilt rider and want a budget-friendly, drop-in replacement for standard cutting, this kit delivers solid value. It’s not for heavy-duty commercial use or specialized mulching/bagging needs—those require a blade design upgrade.
