8TEN LawnRAZOR Mower Blade for MTD Cub Cadet 942-05052A RZT S50 XT1 GT50 LT50 XT2 Troy Bilt (Medium Lift) 3 Pack

What It Is

This is a set of three medium-lift replacement blades designed for 42-inch and 46-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt lawn tractors and zero-turn mowers. The medium-lift profile balances bagging performance with mulching capability, making it a versatile choice for typical residential mowing.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Fits 42-inch and 46-inch decks only. Does not fit 50-inch or 54-inch decks.
• OEM cross-reference: Direct replacement for MTD/Cub Cadet OEM part 942-05052A (also supersedes 742-05052A). Also fits Troy-Bilt models using the same blade.
• Measurement check: Blade length must be 20.5 inches (center hole to tip), with a 1-inch diameter center hole and a 5-point star drive pattern. Measure your current blade’s length and hole pattern before ordering.
• Compatible models include: Cub Cadet RZT S50, XT1, XT2, GT50, LT50; Troy-Bilt Bronco, Pony, Super Bronco; MTD Yard Machines and Yard-Man with compatible decks. Always verify your model’s deck number (stamped under the deck) against the 942-05052A cross-reference.

Key Things to Know

• Star drive pattern: Unlike many blades that use a standard oval hole, these require a star-shaped spindle adapter. If your mower uses a different drive pattern, they won’t fit.
• Medium lift: Good for weekly mowing on typical lawns. Not ideal for very tall or wet grass (use high-lift blades for that) or for fine mulching (use dedicated mulching blades).
• Installation: Straightforward—remove the old blade, install with the lift wing pointing upward, and torque to 70–90 ft-lbs. No special tools beyond a socket wrench and blade removal tool.
• Balance: Each blade is pre-balanced, but it’s wise to check balance after sharpening or if you hit a rock. An unbalanced blade causes vibration and spindle wear.

Should You Buy It

If you own a Cub Cadet or Troy-Bilt with a 42- or 46-inch deck and need a reliable, affordable replacement that works for both bagging and side-discharge, this is a solid choice. It’s not for heavy-duty mulching or commercial use, but for residential mowing at the right price, it’s hard to beat. Just double-check your deck size and drive pattern first.
