How do these ultra high lift blades affect bagging and discharge?

Ultra high lift blades are shaped to create stronger upward airflow beneath the deck, which helps lift grass clippings and direct them toward the bagger or discharge chute. Improved airflow can make bagging more efficient and support cleaner expulsion of clippings, especially in typical lawn-cutting conditions.

• High-lift profile increases suction for better grass pickup.
• Designed to move clippings efficiently toward bagging systems.
• Helps maintain consistent discharge pattern across a 50" deck.

What are the exact blade dimensions and mounting details?

Each blade in the set measures 17-1/4" in overall length and 2-1/4" in width, with a diamond-shaped center hole for mounting. The set of three ensures proper overlap and coverage for a standard 50" cutting deck; these blades are intended as direct replacements, simplifying installation.

• Dimensions: 17-1/4" length × 2-1/4" width per blade.
• Center hole: diamond-shaped to fit common spindle designs.
• Sold as a set of three for complete 50" deck coverage.

How should I install and maintain these replacement blades?

Installation follows typical mower blade replacement steps: disconnect spark plug, raise and secure the deck, remove mounting hardware, and install blades with the correct orientation and torque. Regular inspection, sharpening as needed, and replacing blades in matched sets help preserve cut quality and deck balance.

• Safety first: disconnect the spark plug before working under the deck.
• Install all three blades to maintain deck balance and cutting evenness.
• Check mounting bolts’ torque and inspect blades for wear periodically.

Who is this for? This three-blade replacement pack is for owners of lawn tractors and zero-turns with 50" decks that require 742P05094 / 742-05094 style blades and S-shaped spindles. Choose these blades if you need a direct-fit replacement to restore deck coverage, maintain bagging efficiency, and keep a consistent discharge pattern. If you’re uncertain about fitment, compare your existing blade’s dimensions and center-hole shape or consult your mower’s parts list before ordering.
