Then again, I'm also averse to the lengths people go through to maintain landscaping. Landscaping is necessary, but so many homeowners care so much about property values that they want everything to constantly appear uniform. Some neighbors even rat on each other to their HOA if one person went an extra week without mowing.
With at least the weedwhacker I have, there's not really an option. If you hold the button down, it overheats. If you leave it up to long, it shuts off. As a result, any time I'm walking across pavement, or in between patches that need weedwhacking, I have to rev the stupid thing.
I agree with everything you've said though. I don't have a choice right now, but the way suburban/urban landscaping is done is a nightmare.
Or get a new one if you can afford it. They're not terribly expensive.
It's also not technically mine.
