These T TERRE replacement blades are engineered for homeowners and pros who need a durable, precise blade set for 54-inch mower decks.

How does the medium-lift design affect cutting and clippings?

The medium-lift blade profile balances airflow and lift to eject clippings effectively without creating heavy clumps. This helps produce an evenly cut swath and reduces clogging in typical lawn conditions, while still enabling decent mulching and side-discharge performance when paired with the correct deck setup.

• Medium lift boosts airflow for cleaner discharge
• Reduces clumping compared with high-lift blades
• Works well for general lawn maintenance and light mulching
