I just when back and looked at OP’s 1st post. Particularly at type photos posted.
Some specific comments related to the photos
1) forget trying to crown your complete driveway!
Folks before you go wild!!!! go look at the 2 photos!!! She has spots shown that are mild banked curves, water will always drain to the low side. If you have a stretch of flat area, crowning would be good in those areas.
2) you need ditches! With the trees close to your drive that can be seen, you may not be able to cut ditches with your tractor. Some trees will have to go, while others are going to have roots where you need the ditch to be. Personally, if I were doing it, this is a job for a medium sized mini excavator. Once a ditch is established, by picking the ground conditions it can be maintained and shaped with your tractor and an offset rear blade.
It is difficult to tell based upon the limited view of the photos, but full length ditches may not be what best meets your needs. ‘Short’ (relative term) ditches on the bottom on the curve slope dumping into a natural low spot, built retaining pond, natural creek or other water control feature may better serve your needs.
3) with those ‘banked’ curves, you will have gravel movement. In my opinion it will be pushed to the high side by vehicles traveling too fast. As well as water flow and gravity will roll gravel down hill. You can reduce some of both effects with some fines in the gravel. You do not ever want to have ‘creek’ gravel on those areas. In my area, creek gravel is often solid my land owners that have creeks on their property. It is typically very smooth and will roll/slide always.
