Key Things to Know

• Medium lift: Good for mulching and bagging, but not ideal for heavy, wet grass or thick overgrowth.
• Installation: Straightforward if you have a socket wrench and blade removal tool. Torque bolts to 30-40 ft-lbs.
• Durability: Heat-treated steel holds an edge well, but blades can dull faster on sandy or rocky lawns.
• Balance: Always check blade balance after installation to avoid vibration and deck damage.
