Key Features

• Accurate OEM fit: The blades replace multiple Exmark part numbers so they fit a wide range of Lazer Z, Radius, Turf Tracer, Quest and Vantage 48 in decks when you confirm the model number.
• Precise dimensions: At 16-1/4 in length measured diagonally and 2-1/2 in width, the blades match the original profile for stable rotation and consistent balance.
• Durable thickness: The 0.197 in thickness provides stiffness to resist bending and maintain cutting geometry under typical lawn loads.
• Mulching edge design: The high lift mulching shape delivers clippings that blend into the turf for a tidy finish on many grass types.
• Center hole and lift specs: A 1 in center hole circle and 1 in air lift match common Exmark mounting and airflow requirements for 48 in decks.

Who It's For
