Then detach the blade from its position and put it somewhere safe. Check every side of the blade, and find where the fault hides. 

Step-5: Sharpen the Blade

Stay careful about the safety of your hands as well. If the blade is perfectly balanced, it will hold a perfect 180-degree angle with the screwdriver. When both sides’ weight is not equal, the blade will lower down to the heavier side. You can also balance mower blades with a blade balancer.  

Step-7: Final Touch

If you do not find the perfect balance, you need to eliminate metal from the heavier side with the flat file. Then check the blade balance once again with the same screwdriver method. Keep applying the technique until you get the desired result of both the sides being perfectly balanced. 

Step-8: Re-assemble the Lawnmower

When you get the perfect balance of both sides of the blade, you need to put all the parts back together. Place the blade to its position, and attach perfectly by mounting all the bolts and screws. 

Put all the parts back to their places, turn the mower straight, and reconnect the spark plug. Run a test drive with the mower and check whether the blade is perfectly sharpened and balanced or not.
