Dimensions needed for Mid Mount Grader Blade Bracket

[BradKahler 275]

I'm building a mid mount grader blade for my B80 and I've found a lot of information but I'm lacking a couple of dimensions and an angle.  Any chance one of you might have access to one of these and be willing to provide the needed information?

 

Thanks!

We have a couple Mid Mount Grader Blades here. I can get you those measurements tomorrow. 

 

Have you seen the thread that shows the rest of the measurements?

Yes, I found a thread that had most dimensions but I wasn't comfortable trying to figure out the angle.  I used several different images I found and the camera angle seems to distort the angle enough that each image comes up with different angle.

 

Thanks, any help would be appreciate.

The pivot is mounted at 90 degrees to the frame. That angle is determined by the angle the blade is attached to the pivot.

I don't have factory blade to measure. The factory mounted to the top angle of the blade that gave the angle.

Go down to " wheel Horse Manuals" and look up 40" grader blade. It gives good pictures.

I agree, the parts manual appears to show what would be a 90 mounting.  I even found one picture that sort of gives that impression.  However, I've found several others t hat are distinctly not 90 degrees to the mounting arm.  Needless to say it's very confusing.

Upper distance is approximately 16".

Measuring the whole upper frame, from the front, the angled pin sets here. 

 

And the rear cross pin is at 18".

 

 

 

 

Lower distance is 3".

 

 

 

 

Angle is approximately 105⁰.

Perfect!!  Exactly what I was looking for.  

 

Thank you.

Thanks to the dimensional info from ebinmaine and the information previously posted by others I've made some progress on fabricating the grader blade components.  Other than the block that the lift arm connects to on the main support arm, it's ready to weld together.  The blade itself has previously been fabricated.  I'm currently waiting on the plate that bolts to the blade, I'm having it bent to shape in a fab shop close by.  After that I'll mill the three slots and make the pivot pin.  I'm sure the lift arm won't be exactly like an original, but it should be close enough to function.

Agreed. 

 

I'm looking forward to seeing your completed project.

Looks factory to me. Well done! 

[BradKahler 275]

I tacked welded the lift arm pieces together so I could do a trial fit and everything seems to look good.  I'm still waiting on the bracket for the blade so it might be a few days to a week or so before I can get much more done on it.  

 

Eric, could I trouble you for one more measurement?  I'd like to know the location of the lifting link tab.  I'm guessing it's centered side to side, but knowing the fore/aft location would be a big help.  Thanks!

I can get that for you sometime tomorrow.

OK sooooo tomorrow is actually 3 days...

 

 

 

 

Notice I'm measuring from the SIDE of the large round pin.

Where did you find the measurements to make the frame part I have the blade but I don't have the frame if you could give me the measurements that would be nice thank you

Along with the pictures provided by ebinmaine in this thread, these are the pictures I found on here on Red Square in a couple of different posts.  So far they have given me all the information needed to fabricate the lift arm assembly.
