grader blade size?

I used it for the first time today, fixing the county road that goes to my farm. I have a lot to learn as far as technique and efficiency goes, but I am really happy with it. 8ft is actually a good size. For what I was doing, I could angle it sharply and not need any offset. For most of my work, it’ll be angled the full extent. Tractor felt plenty heavy enough.

I have a 55hp TYM t574, about 65" wide. We have probably a couple of miles of dirt roads on our property in east texas, red clay soil. With heavy rains the roads get a lot of runoff washouts. Ive been smoothing them with a box blade, but think a grader blade that i could cut a runoff ditch on the sides and try to keep crowned a bit would be a better option. Should i look at a 7' with offset ability or an 8'? Or would a regular 7' be wide enough when angled?

Can you use the 3-pt leveling feature to raise one end of your box-blade? If you can, you can make a pass on each side and it will build the crown, just don't try to make it all at once (shallow cuts), make several passes to "sneak up" on the crown.
I do that with my crushed stone driveway because it's easier to make a mistake doing it all at once.
