[nodemcu12ecanada] is serious about saving water, which is why they built this strange lawnmower that can cut grass taller.
Short lawns are one of those clever marketing victories, like convincing people to eat a lot of sugar, that’s been doing more harm than good ever since the victory was won. Short grass is weak grass, with shallow roots, weakness to weeds, and a lot of water requirement. On top of that the grass is always in a state of panic so it grows extra fast to get to a more “natural” height. It’s great if you want to sell fertilizer, seeds, and lawnmowers. Maybe not so great for the environment.
Most lawnmowers can’t even be set high enough for healthy grass so [nodemcu12ecanada] took three electric weed whackers and bolted them to an angle iron frame. It has a lot of advantages. It’s light. You don’t need to sharpen a blade. It’s quiet. It’s electric. It’s strange appearance will scare your neighbors off from borrowing any of your tools. We love it!
