How to change the dual mulching blades on Ego LM2135SP lawn mower

How to change the dual mulching mower blades on the 21" EGO LM2135SP battery-powered lawn mower. The mower blade nuts on the Ego can be quite tight and this video will show you how I was able to remove the stuck bolts and replace the select cut multi-blade system with the standard upper blade and the extended runtime lower blade which allows for a good compromise between runtime and mulching performance for better efficiency while cutting your lawn's grass. You should probably inspect your lawn mower blades about once per season. If the grass on your lawn starts to look kind of ragged with browning tips it could be a sign that your blades are dulling. In my case, my blades were beyond sharpening due to chips so I replaced both. In the video I used this blade kit mentioned below.
