Installation Instructions
Replacing mower blades requires caution. Always ensure the mower is turned off, the spark plug wire is disconnected, and the engine is cool before beginning. Wear appropriate safety gear, including heavy-duty gloves.
- Prepare the Mower: Park the mower on a flat, stable surface. Disconnect the spark plug wire to prevent accidental starting.
- Access the Deck: Depending on your mower model, you may need to raise the deck or tilt the mower to access the blades.
- Remove Old Blades: Use a suitable torque wrench to loosen and remove the bolts holding the old blades. You may need a block of wood to prevent the blade from turning.
- Install New Blades: Position the new Bularie GX21380 blades. Ensure the cutting edges are facing towards the ground. The blades come painted, which may make the edge feel dull initially; this paint will wear off with use, revealing the sharp edge.
- Tighten Bolts: Securely tighten the blade bolts to the manufacturer's specified torque settings. Refer to your mower's specific manual for correct torque values.
- Reconnect Spark Plug: Once all blades are securely installed, reconnect the spark plug wire.

Maintenance
Proper maintenance extends the life of your mower blades and ensures consistent cutting quality.
- Regular Inspection: Periodically inspect blades for signs of wear, bending, or damage.
- Cleaning: Clean grass clippings and debris from the blades and mower deck after each use.
- Sharpening: Blades should be sharpened regularly to maintain cutting efficiency. If you are not experienced in blade sharpening, it is recommended to have it done by a professional or replace the blades.
- Replacement: Replace blades if they are severely bent, cracked, or excessively worn.
Troubleshooting
If you experience issues with your mower's cutting performance after installing new blades, consider the following:
- Uneven Cut: Check if blades are installed correctly with cutting edges facing down. Ensure all blades are tightened to the correct torque.
- Excessive Vibration: This could indicate an unbalanced blade. Inspect blades for damage or ensure they are properly secured.
- Blades Seem Dull: New blades come painted. The paint will wear off during initial use to reveal the sharp cutting edge. If performance doesn't improve after initial use, inspect for damage or consider sharpening.
