this does the job, cuts a much wider path, but it is much heavier than my old 16". I guess a good trade off, takes half the time now but a lot harder to push up the hills! I am using this on very uneven, hilly ground in the country. I have probably an acre all total. I have a riding mower but it scalps the fescue grass so weeds are really taking over, I decided I needed the work out so I would try these and it is definitely helping the grass, much healthier. I can only assume it's doing same for me too. :)
