Naw, DiezNutz. After searching for half an hour or so I was finally able to figure out how to adjust the seat.

But anybody who thinks there's no difference in the operating position "feel" between a 6' person with the seat all the way back and a 6'4" person with size 14 boots with the seat in the same position wouldn't understand what I meant, I suppose--or maybe I didn't explain it well. With some compact Kubotas (the
B2630, which I otherwise really liked, is a good example) the forward HST pedal fit my boot toe fine; but to go backwards required lifting the entire weight of my leg off the pedal and moving my boot toe to the rear end of the rocker pedal. Because of the combination of a fairly low seat height and limited rearward seat adjustment, it was impossible for me to stretch my 68 year old Achilles tendon far enough to press the rear HST pedal all the way down without shifting my entire leg/foot. I could only get about 1/3 to 1/2 travel on it. What's the point of paying for HST for loader work if I have go through gyrations like that? Heck, I might as well clutch and shift every time and save the HST expense.
I didn't try the L or M series, I'm sure they have more room, but I wasn't interested in those lines, only the mid size B's. All other things being more or less equal, JD's twin side-by-side HST pedals simply worked for me where other setups don't. The difference is meaningless to many, it meant a lot to me.
To make you feel better, I've since looked at small backhoe attachments from green and orange, and to my mind orange kicks butt in that category. So everybody does some things I like better than others, it appears. That's what makes the world go round!
