Totally agree. A good utility tractor is as handy as a pocket on a shirt, rough riding or not. If you're going to make your living from the operators station, then pay some mind to ergonomics and comfort. If you're only in the seat for a few hours every month, then simply do the best you can, seat/suspension wise, and go on.
I firmly believe that tractors are like chainsaws, firearms, and Lays potato chips.....one is never enough. Soon, you grow tired of switching implements. Sure would be nice to have a dedicated machine for the box blade/ bushhog/ FEL/......
