Lawnmower..
Lol did some garbage picking (yes i have no class and proud of it) tossed some wheels from harbor freight on it and it pushes like a dream..
I come from a long line of garbage pickers (my grandfather put the "dive" in dumpster diving) so no worries. I like to see stuff get recycled vs. trashed.
Now as for the fat tired lawnmower, I'll go ahead and file it in the damn-good-idea/why-didn't-I-think-of-that bin.
Brilliant!
