Haven't heard the word "strimmer" since I left the UK. Over here, they're called "weed-eaters." When you say "push-mower" do you mean one that's solely powered by human effort? Over here, that term's passe. A "push mower" here is a motorized one that is pushed from behind, rather than the sort that looks like a little tractor and is ridden upon. I haven't seen an actually pushable mower in donkey's years. I tried to find one to buy in VA, and found a metal-framed thing that cost nearly as much as the petrol-powered ones. Ugh!

Later,
