We have a 317 and a 318 there is not that much difference other than power steering and yes I really like the power steering. The 317 has way more options when purchasing implements I myself don't care for the onan engine in the 318 the 317 many came with series 1 engine which gave the 317 the name it has even today. I have a 317 with a series II engine (from a cc 782 lol). Between the both of the ones I have I had rather have the 317 if it had power steering, I just wanted to give a little more info on them.
As far the cub cadet I do like the 782 all around best just like the 317 if it only had power steering. Cyclops are nice also minus plastic. of the cubs I have to get on one and cut grass the 1541 has the most power, leaves a nice cut yard and no having to make engine noise with mouth or between rear end and seat
