Somewhere around here is a thread on using a boxblade, you should read that if you haven't already. I had manual adjust top and side links, drove me nuts and I had a terrible time sorting things out and getting the BB to work properly. Cried when I wrote the check for hydraulic top and side links, now it is a piece of cake to get what I want the blade to do. BUT, if you don't already have rear hydraulics, then the hydraulic Top and Tilt just got about twice as expensive. Since it looks like you are stuck with manual adjustments, make small adjustments, take small bites with the BB and go about as slow as the tractor can. I have found going slow will take longer to get results, but you will get better results. I did buy a large tilt gauge that I attached to the BB so I knew what sort of a grade I was putting on my road.
