The FX800 is nice, just remember it's almost 3' longer (34") than the IS3100. I have the IS3100 with the Kawasaki 37 hp and added a suspension seat because I mow lots of rough ground. It turned a teeth jarring event on the lawn tractor to almost fun. I spend less than half the time and I mow more. I wanted one good mower before I die........![]()
the extra length is not a problem. I like the fact that the deck raises up so you can get to the blades easier
