Have to second the comment about EE Bota's great post. Just to support what he said for Scotty, I likewise have a BX2230 with a standard sized 48" box blade, and have moved quite a bit of dirt with it over the last 5 years. You can absolutely fill it so full the tractor won't pull it.
As EE notes, keep the rpm's up so the hydraulic flow is strong. If you baby the throttle in the misplaced hope of taking it easy on the machine, you increase the chance of doing damage. Learn to feather the HST treadle instead of backing off the rpm's.
As long as you do good maintenance and don't misuse the throttle/hst, as noted by EE, your BX will work as long and as hard as you will ever need.
Also, it takes some practice working with the 3 pt lift control. It's quite easy to get too much in the box, followed by raising it too high so it all drops out again. But keep trying; it does get easier.
