3 Pack 50" Mower Blades 2-in-1 Compatible with Cub Cadet Troy Bilt MTD ZT1 ZT2 XT1 XT2 L50 KH LX 50 KW Replaces 942-05052A 742-05052A 50 Inch Cut Deck Lawn Tractor Riding

What It Is

This is a 3-pack of 50-inch 2-in-1 mower blades designed for zero-turn and lawn tractors with a 50-inch cutting deck. They work for mulching or side-discharge (not bagging) and are compatible with Cub Cadet, Troy-Bilt, and MTD models like the ZT1, ZT2, XT1, XT2, L50 KH, and LX 50 KW.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 50 inches from blade tip to tip. These blades replace OEM part numbers 942-05052A and 742-05052A. They fit Cub Cadet, Troy-Bilt, and MTD models with a 50-inch cut, including ZT1, ZT2, XT1, XT2, L50 KH, and LX 50 KW. Measure your existing blade length (center hole to tip) and check the center hole diameter (typically 1-inch or 7/16-inch). These are aftermarket blades, not OEM, so verify your spindle pattern matches—most use a 5-point star or oval center hole. If your deck uses a different blade offset or thickness, these may not fit.

Key Things to Know

• Quality vs OEM: These are aftermarket blades, usually made of hardened steel. They’re durable but may wear faster than OEM Cub Cadet blades, especially on heavy or rocky terrain.
• Installation: Easy to swap—remove the old blade center bolt (use a socket wrench), install the new blade with the lift wing facing upward, and torque the bolt to 40-50 ft-lbs. No special tools needed.
• Common Gotcha: 2-in-1 blades don’t work well for bagging—they’ll leave clippings on the lawn. Stick to side-discharge or mulching only.
• Balance: These come pre-balanced, but always check with a blade balancer before installing. An unbalanced blade causes vibration and damages the spindle.

Should You Buy It

Buy this 3-pack if you need a budget-friendly replacement for a 50-inch Cub Cadet, Troy-Bilt, or MTD tractor and only use mulching or discharge. The high rating and low price make it a great value for light-to-medium duty mowing. Skip it if you bag regularly or need OEM-grade durability for heavy commercial use.
