Compatible Brand and Deck Path

These blades are intended for select Cub Cadet 46-inch mower decks that originally use the 742P05510-L low-lift blade path.

• Cub Cadet: Select 46-inch mower decks using 742P05510-L blades
• Packaged Blade Path: 490-110-C199 and 490-110-Y199

Fitment note: Model names and deck sizes are only starting points. Cub Cadet produced multiple 46-inch blade systems with different center patterns and cutting profiles. The original part number and blade-center shape should control fitment.

Low-Lift Blade Applications

Low-lift blades generate less upward airflow than standard high-lift or Xtreme-style blades. They are commonly selected for mowing conditions where reduced lift, reduced dust movement, or lower airflow is preferred.

• Reduced airflow beneath the mower deck
• Lower dust movement in dry mowing conditions
• Suitable for applications originally equipped with low-lift blades
• Not intended as a direct cutting-style substitute when the mower originally requires a high-lift or mulching blade

Blade Style Warning

Do not confuse 742P05510-L with other similarly numbered Cub Cadet blades.

• 742P05510-L: Low-lift blade path covered by this listing
• 742P05510: Standard high-lift blade path
• 742P05510-X: Xtreme or mulching-style blade path

These blades may have similar overall dimensions, but the lift profile, center pattern, and intended mowing performance can differ. Match the complete suffix and original blade specifications before ordering.
