(ET) dozer blade and driveway maintenance

[SteveS <ssawtelle erols com>]

I've been using my dozer blade a fair amount; reworking the gravel 
driveway and clearing out a decent snow (finally!). During all that 
quality time I've noticed some things about the dozer blade that seem 
wrong for what I want to do, or maybe I'm doing something wrong, so let 
me explain what I'm trying to do and maybe you all can tell me how to do 
it better...

I have a long gravel driveway (~1/4 mile) and it has (when graded right) 
 a bit of crown and small ditches on each side. Over time gravel moves 
towards the sides and fills the ditches. So what I want to do is push 
the gravel back into the drive and clean out the ditches. I set the 
blade angled pointed towards the center of the drive and drive down one 
side of the drive with the edge of the blade in the ditch. However when 
the blade is angled it also tilts a bit (side to side) and the tilt is 
the wrong way (high side on the ditch end). When pushing snow, I want to 
angle the blade the other way to push snow off the drive, but here, the 
low side is in the ditch and it leaves snow in the middle. I would think 
both problems would be solved if the blade tilted the opposite way in 
each case.

As I see it, the blade tilts because the support actually has some 
upward  angle to it (from back to front) even when lowered to the 
ground. The blade tilt is even more pronounced when it is lifted. If the 
support angled down from back to front when lowered I would think the 
blade would tilt the way I want. I'm thinking of making a new blade 
mount that has the pivot bar raised up higher, but I'd like to get 
thoughts from the group. Maybe I'm just doing soemthing wrong?

Thoughts?
