Just a note about box scraper use: I used the scraper with the hydraulic top link for the first time several days ago. Between the link and the lift, I was able to do some decent grading without getting off the tractor except to change the lower link level. If I was doing a bunch of this type work, a hydraulic lower link leveler might be good, except I can see myself ending up with a tractor festooned with hydraulic hose.

I was building up a previously graded pad for a mobile with gravel. The job was mostly dragging material around, so I wasn't using the link much to adjust between cutting and spreading. Even so, I made several dozen adjustments. The link makes a big difference. For example, the best tilts for dragging material and for dozing with the rear cutter are different. Without the hydraulic link, I probably would have set a tilt that sort of worked for each, rather than getting off the tractor to change the tilt.

I even found that the scraper does a better job of smoothing than the back of a loader bucket. With the link fully extended, the scraper can be floated on the back of its rear cutter. I'm not sure a standard link would extend far enough for that trick. A lot of the way a scraper behaves seems to depend on whether the surface is packed enough so the side plates will float. Of course, they just sank in the newly spread gravel, so I had to use position control most of the time.
