I purchased my Yarbo to take on the mowing maintenance work of my property, about 1.6 acres of grass in total. I have wide open skies and both GPS and HaLOW work like a charm. The mowing experience has been mixed. Yarbo is excellent for Kentucky blue grass sod. It's not so great at longer field grass (fescue/rye/buffalo mix) mostly due to the the mower design. I've had some minor hiccups with Yarbo getting stuck due to "obstructions" which aren't real and I have to prod it along. So there are ups and downs but I haven't touched a mower all summer so it's taken all the work off of the family, freeing up time for hobbies, sports, etc., which was our goal. I'd say Yarbo takes more frequent maintenance (weekly greasing, monthly blade changes, cleaning out grass, etc) than a traditional mower but it's less work each visit, if that makes sense.
