Duragrader Update

   / Duragrader Update #11  
I am not sure how they set up their blades in relation to the side rails on the Duragrader, but I built my own grader box that is similar to the one shown on their website. On mine, I placed the cutting edge of the front blade about 3/4" below the side rails and the rear blade is set flush with the side rails. It takes a little bit of trial and error to set the toplink up properly to control the cut. I found that by setting it up initially on my garage floor, I could get it pretty close to the sweet spot right from the start. Once you are in the "zone", a fairly small adjustment on my toplink has a pretty large impact on the way mine cuts. I let the impliment rest on the garage floor with the 3PH in "Float". Setting on the garage floor, the only points on the impliment that are touching are the cutting edge and the rear ends of the side rails/skids. I lengthen the toplink till it is tight and the cutting edge just starts to lift off the concrete floor. On a level surface, that will be the no-cut position. I only have to shorten the toplink a small ammount to increase the ammount of cut to it's maximum where the siderails will be sliding completely on the ground and the blade cutting in 3/4". I think that only takes about 3-4 full turns on the toplink on mine so it is pretty sensetive. If I shorten it too much, the grader will actually start to ride up on the side rails ahead of the blade which will cause the blade to cut less(but not so much on mine as I put the front blade pretty far foreward).

This thread is a review of a Duragrader a few months ago. There have been other members with posts about them. You might make a few PM's to find out about adjustments...
Glad to hear you finally got the thing!

<font color="blue"> They sure make it sound like you don't have to fiddle with adjustments like you do with a boxblade, don't they? If I had bought it, I'd be asking the same questions. From their advertizing, you just drop it and go. It'll put a great crown and finish on your road. </font>

Yes, and I believe they also said quick shipping too. /forums/images/graemlins/crazy.gif

Wayne,
Actually, the blade side closest to the tractor should be the side that goes to the center of the road since you will be picking up the front just a little. That means the right side will dig less than the left if the front is raised just a little. The dirt displaced should ride to the left as it builds up against the blade, but fills in the low spots as the right side will be higher due to being closer to the front.
Hope that makes sense. The duragrader is built to appear level, and that is very misleading. I dragged it all around the south before a stanger pointed out to me that it wasn't going to cut a level path with the blades angled like that unless you kept it exactly level. After figuring that out, it made perfect sense.
Good luck with it, and let me know if you have any problems with it.
Since I bought those extra blades, I will probably go ahead and build one soon.
I started building myself another computer last night.
Been years since I did that, and it isn't as easy as it used to be. Getting tired of not being able to acess the 'net. Wish me luck replacing that old dead computer.

It is good to see you are at least back on line! I remember your instructions and have been playing with the setup. Obviously there is a sweet spot that I have not found yet. Looking at the thing it seems to defy gravity. I can tell you it works very well but I just don't have the setup/crown thing figured out yet. Thnks again for your help.
