Like B2400, I also liked having a suspension seat because of my bumpy terrain. Mine is a 2002 B7500 and I liked the original seat, just not the 2 springs they use for a suspension. I also bought the suspension seat from TSC, but didn't like the seat, especially the wrap-arounds on the back piece. Luckily, the original Kubota seat, made in my home state of Michigan, easily came apart and allowed me to drill holes and weld nuts on the inside of the metal shell to line up with the holes on the suspension mechanism. Some simple cross pieces had to be made to adapt the mechanism to the tractor. And like B2400, the seat is higher but it more comfortable and gives me a better view (I'm only 5' 10"). If the angle of the seat is an issue I would think that some shimming underneath could solve that problem.
