Well if it is in really nice shape, thats not out of line for a starting point. Anything decent bare one brings between 5 and 7, loader and condition drives it higher, with the 1969 and later ones topping them all.
Since I mentioned about putting the larger 34 inch wheels on mine, remembered I had some pics which show just how much diff it made. Maybe looks a bit screwy having the smaller cast weights on the larger hubs, but they fit perfectly just the same.
Ended up having to take the door off as it wouldn't open far enough as it hit the tire, gonna remount it so it opens forward instead. My custom built battery box/step, well the tire just clears the step by half an inch, so without mods won't be tire chains going on any time soon either. But the diff those bigger wheels make is beyond words really. Nice to be able to do something as simple as drive over a swath while baling and not drag fifty feet of it with me as I do. I knew there was a few standards out there with the 34 inch, but I had never once ever saw one in person. Been a few others that seen it sitting in the yard and noticed she sits a lot higher on the ass than most. It spent 10K hours with the little ones, was 100 into the second round when I made the change, now we'll see if it or I make it long enough to go around again lol.
