Had some fuel pump issues on my walker and got to demo a gravely 280 i beleive. A monster of a machine. Hardly could handle the beast in a couple tight areas. i found it did best on the street, where i could go fifteen mph. The steering was lame, no grass handling system. Man did i miss my walker after being on this machine for two passes. I set the deck height which is determined by these little weenie peices of plastic that one inserts onto a coloumn as spacers which raise the deck. I set the deck at four inches to play it safe and either didn't cut some grass of scalped other spots. when the call came in the same day that my walker was ready i couldn't wait to pick it up. Get a gravely if you have 20,000 sqft yards you want to mow in 1/2 hr, or a golf course, but i would not endorse getting one of these as your go to mower.
