CUB CADET 742P05094 17.271" High Lift Blade S-Shaped Hole Enduro XT1-LT50 Ultima ZT1-50 ZT2-50 6-Pack

What It Is

This is a six-pack of OEM Cub Cadet high-lift blades (part 742P05094) designed for aggressive grass clipping discharge on 50-inch decks. They’re built for Cub Cadet XT1-LT50, Ultima ZT1-50, and ZT2-50 tractors, plus select Enduro Series mowers, where standard blades leave clumps or wet grass trails.

Fitment & Compatibility

• Deck size: Only for 50-inch cutting decks. Measure your deck width before buying—these won’t work on 46” or 54” decks.
• Model check: Fits XT1-LT50, Ultima ZT1-50 (2019+), ZT2-50, and Enduro Series with 50” fabricated decks. Confirm your mower’s deck model number (e.g., 50F or 50FA) in your manual.
• OEM vs aftermarket: This is a genuine Cub Cadet part, not a generic. No fitment guesswork if your deck matches.
• Blade specs: 17.271” long, 0.250” thick, 1” center hole with S-shaped drive hole. Measure your existing blade length and hole pattern to verify—S-shaped holes are less common than oval or star.
• What to skip: Not compatible with stamped steel decks or older LT-series (e.g., LT1040 or LT1050) with 50” decks—those use a different blade shape.

Key Things to Know

• High lift = high power draw. These blades create strong upward airflow to discharge clippings, but they strain the engine more than standard or mulching blades. Expect slightly slower ground speed in thick grass.
• Installation tip: Use a torque wrench to tighten blade bolts to 70–90 ft-lbs. Under-torquing can cause blade shift; over-torquing can strip the spindle threads.
• Wear check: High-lift blades dull faster than low-lift or mulching blades because they contact more debris. Inspect after every 10 hours of mowing and sharpen or replace as needed.
• S-shaped hole gotcha: The S-shaped drive hole matches Cub Cadet spindles only. If you’ve replaced spindles with aftermarket units, verify the drive hole shape—some aftermarket spindles use a star or oval pattern.

Should You Buy It

Buy this six-pack if you have a Cub Cadet 50-inch deck (fabricated, not stamped) and regularly mow tall, thick, or damp grass where standard blades leave clumps. It’s a premium OEM solution for clean discharge and even bagging, but it’s overkill for dry, short lawns or if you prefer mulching. Skip it if you need blades for a different deck size or a non-Cub Cadet mower—fitment is strict.
