3-Pack High Lift 17.28" Mower Blades with Nuts & Washers for Cub Cadet XT1-LT50 Ultima ZT1-50 ZT2-50 Replacement for 742-05094 742P05094 490-110-Y193, Fits 50 Inch Deck, Diamond S-Pattern

What It Is

This is a 3-pack of high-lift, 17.28-inch diamond S-pattern mower blades designed for 50-inch cutting decks on select Cub Cadet models. They’re built for bagging and side-discharge performance, with included nuts and washers for a complete swap.

Fitment & Compatibility

• Deck size: Fits 50-inch decks only. Measure your blade length to confirm—17.28" is the critical spec.
• Models: Cub Cadet XT1-LT50, Ultima ZT1-50, and ZT2-50. Also replaces OEM part numbers 742-05094, 742P05094, and 490-110-Y193.
• Center hole: Typically 1" diameter with a 5-point star drive. Verify your spindle’s center hole shape before buying.
• OEM vs aftermarket: These are aftermarket blades. Check that the thickness and lift profile match your original—high-lift blades increase airflow but may strain engines on lighter-duty mowers.

Key Things to Know

• Installation: Simple bolt-on with included hardware. Torque nuts to 70–90 ft-lbs. Use a blade removal tool or wedge to lock the spindle.
• Performance: The diamond S-pattern improves mulching and bagging over standard blades, but expect slightly higher noise and fuel consumption.
• Gotcha: High-lift blades create more suction—they can stall the engine if grass is wet or thick. Not ideal for low-horsepower (under 20 HP) tractors.
• Durability: Heat-treated steel holds an edge well but will dull faster if hitting rocks or roots. Sharpen every 25 hours of use.

Should You Buy It

If you own a compatible Cub Cadet with a 50-inch deck and primarily bag or side-discharge, this 3-pack offers good value. Avoid if you need low-lift blades for dry, dusty conditions or have a mower under 20 HP.
