Ok, if this has been answered before, I apologize up front. I have an x300. When I bought it, I thought I understood how the series gets it's numerical designation. the bigger the number, the higher the horsepower, larger decks, etc. If the last digit was a 4, it meant that the tractor had 4-wheel steering.
Well, that's been a while ago, and now there are all kinds of model numbers in the 3, 5, and 7 series. For example, what's the difference between and x740 and an x738 or x739? Why was the x300 discontinued? Looks like the 350 is the equivalent model? I'm just wondering how these models got their names. I think the 4 still indicates 4-wheel steering, but I'm not sure about any of the others. Thoughts?
