My 2 cents here. Page 22 of my owner's book show the basics of this. Have to admit I bought the tractor thinking it was a real tractor with the usual three point that most of the tractors I have had. Of course my stops were out of adjustment and set too far in. Even with them adjusted, my grading is very difficult with the rear blade. So, if I see someone trying to decide about the B or BX, I relate my opinion.
