Other construction grader blade

Other construction grader blade.

Is it for snow, or gravel. Does not look very beefy for gravel. My Volvo with a new cutting edge on a flat surface will swing without having to touch the blade height. But as the cutting edge wears, I have to compensate for the downward angle on the drawbar when I swing. How would you keep that on grade.

This is for gravel and other material. I read the report in the German grader forum today.

if you look close, there is no circle, so the blade has a hinge in the middle, letting you select your blade angle/angles with the cylinders. It doesn't look like it has curl or blade slide functions.


been a few times I could have a used a blade that did that.

True, but the angle would still change as you raise or lower the blade. Look at the picture with her in full V. The sides are on the ground and the center is up. Have to see it in person I guess.

Here is a video from that type of blade:

Hm, there is no sideshift anymore, that is not so good I think... I know a grader operator , which use very often the site shift and the circle rotation.

First, I am not saying the blade won't work, and I can't really judge it's geometery without seeing better pictures of it on the grader. In the video, it is on a 3 point hitch, and the draw bar can be lowered at the front. Now I know that other grader operators know what I mean, but in order for the blade to work, the draw bar needs to be level from where it pivots behind the front wheels to the center of the blade. A conventional grader blade will work with the draw bar at any angle because you can compensate by raising one side, and or lowering the other. Kind of like picking the blade up for walking her up and down the road. If you raise the blade up full height, and turn the circle as tight as you can, the leading edge of the blade will be close to the ground, and the heel of the blade will a lot higher. With the draw bar off level, and this blade in full V, front or back, the center will either dig in, or raise up, and no matter what you do to the right or left side, it can't make full contact. The only way it can work in V, is if the blade can stay 90 degrees with the ground, or if the draw bar can be kept level by adjusting the pivot in the front...Someone tell me that the know what I am trying to say.....

Yes I think, that we should see better videos/photos from a real grader to see all the function. I think with the V-Moves you can work like a sideshift when you have a barrier on the way or tree etc. The blade is max 4 metres long the reaches away from the wheels are 1,25 m.

That would be what the pitch cylinder in the center is for, I would guess.

It also still has center shift, so I can see it working fairly well. Like anything, you trade somethings off to gain others. The option of being able to V plow, or U doze would be handy at times.

on edit:
After watching the video posted above, it seems that I was wrong and it is not a pitch cylinder, so now I too question how well it works in any position other than ideal.

Exactly. It would be ok for some applications, but for fine grading, unless the blade was in the straight position, it would either dig out the center, or leave it high. An example would be watching a V snow plow. On the ground, as you move the V, the linkage moves up or down in order to allow for the changing angle of the plow.

Here is a video from the blade on a motorgrader:

I hope they will show another video with earthmoving works, for example like this type of works, the circle is used here:

Ok. This video answers my question. As I said, in order for the V to work, the draw bar must be level, or the pivot point of the V must be 90 degrees to the ground. About 1:45 into the video you can see that the front of the draw bar can raise, and lower in order to address this. I wondered how they would do this, and now I know.

im sure it would have its advantages, it also has its disadvantages. with the wide flat bottom of the blade, I think it would make cutting hard material a little problem. using your blade to reach out and gouge some thing I think is out. don't know how well it would work with gps, as there is no rotation sensor but im sure someone will figure it out.

Do you think that those type of grader jobs are possible too?

Stehr in the German forum gives no answer about that and how much the blade can change.... I think they loose lots of important grader functions... but the german people don't understand that.... they think a grader can only move gravel.......

I agree that the grader will loose lots of functions. Just a quick view through some of the posts of the forums here, or some of the videos on youtube will show some of what a grader can do. some times operators are only limited by their imagination.

As a front dozer blade, I think it would be super helpful. but its not some thing new. Ive seen a few companies that make blades like that for the front.

Im still not sold on that style of blade. I like the traditional style of blade that has a sharp edge to grade, shape, cut, pick out large rocks, asphalt , do concrete break out, stack gravel, or snow, cut ice, ditching, use the corner to rip/gouge, trench,. lift signs, reset manholes, water valves. these are just a small list to of things that grader operators do daily with there machines. ( i know im missing a LOT of things. but that's all that comes to mind)

Thanks for picts and video. something to think about.

Stehr want to show next time a better video with more functions, they will make some test on a bigger place. I think then we will know more.

Excellent. Cant wait to see them. I enjoy the database. keep up the good work.

I'm glad that you like my database collection about different graders, thanks We in Germany have most graders with dozerblade, so I wonder, why not all graders have those interesting blade for making small bulldozing jobs.

I have find a better photo from the universal blade:

I think taluld works are possible too.

How it works.

The idea with this type of blade is not new, here are videos from this older type of blade:

Interesting that Stehr steal this idea....
