Traction was one of the reasons I just traded in my x300 to be honest. My traction issues were mostly in the winter trying to blow and drive through cement-like slushy snow. My issues weren't that the x300 couldn't take the load, as I'm not a small human being myself, it was that it only let one wheel have power at a time, and that wheel was usually the one that was on the slippery spot! I have, though on occasion hauled some pretty heavy loads with it without issue and as long as you don't go crazy and expect it to do the work of a bigger tractor, it'll do just fine. The only issue I had while mowing was a ditch in front of my house that I had to be careful how I approached. If I had to stop or slow down on the way up, unless I was facing directly up the slope, the wheel on the upper side would get the traction and spin, sometimes ripping up some grass if I wasn't careful. that was only a big issue when the grass was a little damp. All in all though, my x300 was a little trooper and did most of what I asked it to do without issue these past 6 years but like anything, I was ready to move up to a bigger setup to get rid of the small annoyances, so I ordered a 7 series with 4wd.
