942-05052A Mower Blades for Cub Cadet ZT1 ZT2 Ultima Zero Turn XT1 XT2 Enduro Series LT50 GT50 RZT50 RZT-L34 50'' Deck Lawn Tractor Replaces 742-05052A, High Lift, 6 Point Star, 6 Pack (Black)

What It Is

This is a 6-pack of high-lift mower blades for 50-inch cutting decks on Cub Cadet ZT1, ZT2, Ultima zero-turn mowers, and XT1, XT2 Enduro Series tractors, plus RZT50, RZT-L34, LT50, and GT50 models. They are designed for aggressive grass clipping lift and discharge, ideal for thick or wet grass.

Fitment & Compatibility

• Deck size: Only for 50-inch decks. Measure your deck width – a 48-inch or 54-inch deck will not fit.
• Blade measurements: Each blade is approximately 20.5 inches long, 2.5 inches wide, with a 0.25-inch thickness and a 6-point star center hole. Confirm these dimensions match your existing blade.
• Replaces OEM part: 742-05052A (Cub Cadet OEM). This aftermarket set is a direct replacement.
• Models that fit: ZT1, ZT2, Ultima ZT series; XT1, XT2 Enduro Series; LT50, GT50, RZT50, RZT-L34. Check your model number and deck serial tag for exact confirmation.
• What to check before buying: Measure your blade length (center hole to tip), verify the star pattern (6-point, not 5-point), and ensure your deck is 50 inches. If your deck uses a different blade mount (e.g., oval hole), these won’t work.

Key Things to Know

• High lift design: These blades create more suction for better bagging and discharge, but they also increase engine load and may throw clippings farther. Not ideal for dry, dusty conditions where you want less wind.
• Installation difficulty: Easy for DIY – typically a 15-30 minute job with a socket wrench and blade removal tool. Always disconnect the spark plug and battery before working.
• Common gotcha: The 6-point star center hole can be tight on some spindles. If your old blades have a smaller center hole, these may not seat properly. Measure your spindle shaft diameter (usually 1 inch) to confirm.
• Balance: Aftermarket blades may need balancing before installation. Check with a blade balancer – an unbalanced blade causes vibration and poor cut.
• Quantity: 6-pack covers a 3-blade deck with 2 spare sets. If you have a 2-blade deck, you’ll have 4 spares.

Should You Buy It

Buy these if you own a Cub Cadet 50-inch deck zero-turn or tractor and want an affordable, high-lift blade replacement for bagging or heavy grass. They’re a solid value for the price, but avoid them if you prefer low-lift blades for dry, sandy conditions or if you need exact OEM fitment with no tolerance risk.
