Funny how in your attempt at sarcasm, you actually capture the truth, and yet you don't understand why.
If you start to think about jobs requiring chippers, chainsaws and jackhammers, you might see the difference.
I have a large number of branches from the recent storm that I could use a chipper for, though I could just haul them off as-is, that seems like a bit of a waste. There's a log and a few stumps that I'll pretty much need to use a chainsaw to clear out an axe would eventually get the job done, but again, a waste of time. If I want to put in a new patio, I'm going to need a jackhammer to remove the old concrete slab. I suppose I could get it done with a sledge, but that's a lot of back-breaking labor. If my yard is covered in leaves, a blower will get it cleaned up a whole lot faster than a rake.
In other words, the jobs that those tools are designed for are all things I might need to do in my own yard. And they are all labor-saving devices.
You don't get it, even when you need to use the tools at hand. What is the difference between the typical jobs requiring chippers, chainsaws, and jackhammers vs. leaf blowers?
