The 600/800 series and the later 601/801 series have several submodels. The middle digit in the 3 digit model number will designate transmission/pto arrangement. For a live pto with a 5 speed trans you want to see a 6 in the middle of the model number (ie, 660,860,661,861). With the later SOS automatic trans, the live pto will be designated by another digit which I can't remember offhand. The link below will give more info. As far as power steering, I think you need to look for a 601/801. I don't think the earlier 600/800 series had factory p/s although I've read posts that indicate that they can be converted.
