Been seeing alot of friction on here about these mowers. Just had a couple of questions? Can you get a Badboy that is driveshaft driven? What kind of warranty do they have? Also they look a little top heavy. How much can you adjust the height of the deck? 1/2 inch or 1/4 inch increments? up to how many inches? 4 0r 5? Don't know much about these mowers but there seems to be a few that does.
