CUB CADET 942-04308A 21.23" Blade 2-Pack RZT42 XT1-LT42 XT2-LX42 LTX1040 LTX1042 ZT1-42 42" Mowers

What It Is

This is a genuine OEM 2-pack of 21.23-inch mower blades designed for 42-inch deck Cub Cadet and MTD-built lawn tractors and zero-turn mowers. It’s a direct replacement for the factory blade on models like the RZT42, XT1-LT42, XT2-LX42, LTX1040, LTX1042, and ZT1-42.

Fitment & Compatibility

• Deck size: Only for 42-inch cutting decks. Measure your blade length – it must be exactly 21.23 inches (539mm) center hole to tip.
• Model match: Confirmed for Cub Cadet RZT42, XT1-LT42, XT2-LX42, LTX1040, LTX1042, and ZT1-42. Also fits many MTD, Troy-Bilt, and Craftsman 42-inch decks using the same OEM part number.
• OEM vs aftermarket: This is genuine Cub Cadet (OEM) – no fitment guesswork. Aftermarket blades may be cheaper but often vary in thickness, hole diameter, or balance.
• What to check: Verify your current blade’s part number (often stamped on it). Also confirm the center hole is 1 inch (25.4mm) and the blade is a standard straight design (not mulching or Gator style).

Key Things to Know

• Quality: OEM blades are heat-treated and balanced from the factory – they last longer and cut cleaner than many cheap aftermarket options.
• Installation difficulty: Easy – just a socket wrench and a block of wood to keep the blade from spinning. Torque the bolts to 40–50 ft-lbs.
• Common gotcha: These are standard lift blades, not mulching blades. If you want finer clippings for bagging, stick with OEM; for heavy mulching, consider a dedicated mulching blade set.
• Price vs value: At ~$26 per blade, this is mid-range. OEM is more expensive than no-name brands but less than premium aftermarket (e.g., Oregon). The 2-pack saves you from buying singles.

Should You Buy It

Buy this if you own a Cub Cadet or MTD 42-inch deck mower and want a guaranteed fit with OEM durability. It’s ideal for standard cutting and bagging – not for heavy mulching or rough terrain. If you’re on a tight budget and don’t mind checking specs, aftermarket blades can work, but this pack saves time and hassle.
