Some shots of the progress on the 3pt hook up and the up and down adj. for the blades. At first I was going to just put a ridgid 3pt. but then decided that a "floating" top link might help the blade follow the grade changes (up/down hill), thinking that this will keep the blade on the ground and keep it from cutting in (or lifting up) when the tractor is not on the same "plane" as the grader, I was thinking about how a properly adjusted bush hog or rear finish mower has that type of top link adjustment to keep the mower from doing as described. I thought about just using a chain, but with a little thinking I came up with a swinging link that allows about 10" of travel before the top link reaches it limit. I hope that this is not too much. I figure that I'll set it in the middle and have equal movement in either direction. I also made to lay flat by pulling one pin when using it on the skid steer. (the first 4 pics) The other 4 show the blade adjustment. I just went for simplicity and used a pc. of 1" all thread and made a crank/handle for it. It is all bolt on in case I later find that frequent adjustments are handy and hydraulics are needed. I tried to show the adjustability with the one photo showing the blade all the way down for spreading, about 3.5" and the other (hard to see) shows the other extreme, with a 1.5" cut (runners above the cutting edge). It ended up with 5" total vertical travel, and I'm wondering if I should have split the travel (2.5" above or below) and be able to get more wear out of the cutting edges ($350/pair). If this proves to be a problem, I'll drill another set of mounting holes below the existing ones to gain more blade life.
