Tools and Materials Required

Step-by-Step Instructions
1. Safety First
Before you begin, park the mower on a level surface and engage the parking brake. Disconnect the spark plug wire to prevent the mower from starting accidentally.
2. Remove the Old Blades
Locate the blade bolts on the mower deck. Using a wrench or socket set, carefully loosen the bolts but do not remove them completely. Wear gloves to protect your hands from sharp edges.
3. Inspect the Blades
Once the bolts are loose, carefully remove the old blades from the mower deck. Inspect the blades for any damage or wear. If the blades are damaged, replace them with new ones.
4. Install the New Blades
Align the new blades with the mounting holes on the mower deck. Apply a thin layer of anti-seize compound to the bolts to prevent them from seizing.
5. Tighten the Bolts
Using a torque wrench, tighten the blade bolts to the specified torque. This ensures that the blades are securely fastened but not overtightened.
6. Reconnect the Spark Plug Wire
Once the blades are installed, reconnect the spark plug wire and start the mower. Listen for any unusual noises or vibrations. If you notice anything out of the ordinary, stop the mower and recheck your work.
