Right. As I may have mentioned earlier, I have a B&D battery-powered blower, used it after cutting the lawn, mainly to clear off the tractor (I'm pretty good about minimizing how much grass gets on the pavement).
That was perfect, got about 10-15 minutes out of a battery. Eventually, those batteries died, and I made the change to Milwaukee M18, but have been using my Echo backpack blower for the tractor cleaning. The power of that thing is incredible.
I will probably get an M18 blower eventually for all the reasons mentioned (by others) above.
(One good thing about using the backpack blower is that it forces me to use it more frequently, which can only be a good thing for a gas engine.)
