How are these blades shaped and what cutting style do they provide?

The Aeagle blades are medium-lift type, a balance between low-lift and high-lift designs that helps move clippings effectively without demanding excessive engine power. Their profile promotes a clean cut and decent bagging or side-discharge performance depending on your deck setup.

• Blade length: 18 5/8"—designed for 54" deck spacing and spindle alignment.
• Air lift (blade curvature) about 1 1/7" to create moderate airflow for clipping control.
• Medium thickness and width to balance durability and cutting efficiency.

What are the build details and maintenance tips?

Aeagle blades come finished with a safety paint along the cutting edges to prevent corrosion during transit; that coating will wear off during initial use. You can resharpen the blades safely when they dull, but check for cracks or bends and replace blades if damaged.

• Material and finish designed to resist rust until first use; cutting edge paint will wear with mowing.
• Center hole is circular—match your spindle hardware and blade bolt pattern before installation.
• Resharpen with a bench grinder or file, keeping the original bevel angle; replace if warped or nicked beyond repair.

How do I install these blades and ensure safe operation?

Installation is straightforward for anyone comfortable with basic mower maintenance: secure the tractor, support the deck, and tighten blade bolts to factory torque specs. Always use proper safety gear and follow your tractor’s service manual for spindle and mounting instructions.

• Disconnect spark plug and lower deck to a service position before beginning work.
• Install blades with the correct orientation (cutting edge forward) and torque bolts to manufacturer recommendations.
• Check blade clearance and balance; spin by hand to confirm no interference before use.
