I was going to say that grass is pretty much always grass. But I suppose in the spring it grows really fast (heavy wet storm), and in the middle of summer it slows down (light fluffy snow).
However, you will never have a case where you can't get to work because the grass sprouted up overnight. Or because your mower won't start today. A mower failure is never an emergency. But a blower failure, when you've got 12" of heavy stuff, that could be termed an emergency, at least in my book. I don't want to shovel it, at least
Hey, once you discover the magic of just walking behind a noisy machine, a shovel becomes less appealing.
Multiple blowers will ensure that you've at least got *something* better than a shovel, even if one breaks a belt, snaps a shear pin, etc. And you have the proper tool for the job, whether it's a deep heavy job with significant EOD, or a job that's 2" of fluff.
I do have 2 mowers, I suppose, my lawn tractor and my walk-behind. I do need something to get into the little areas that the tractor can't reach. Plus the weed whacker.
And you'll never cut your grass with scissors. So mower =/= snowblower. Mower = shovel, if you want to make the comparison as the simplest tool for the job.
