Raposo 530 #1 Posted January 22, 2021 Hey guys, this is going to be my build thread for my mid mount grader blade. I am using a 42" dozer blade for the majority of the build that I got for free. Its missing the angle level handle and brackets, so I figured its a great candidate for this! Wanted to also have people post up mid mount grader blades they have building. So far I have cut the A frame down to about 20" and have it welded together. I will get some pictures and post it up. Next I will be cutting the blade down to about 6" in height. and removing the trip springs and welding it solid. 5 1 Share this post Link to post Share on other sites
Pullstart 62,805 #2 Posted January 22, 2021 Will this still mount like a snow blade? Maybe replacing the springs with adjustment arms would be advantageous? Share this post Link to post Share on other sites

Yes, it will mount to the rear axle mounts like dozer blade. I thought about that but I don't think I will have enough height since the blade will only be 6" tall or so. 2 Share this post Link to post Share on other sites

I have a mid mount grader on my Commando 6 right now. If you need any measurements... 2 Share this post Link to post Share on other sites

Raposo 530 #13 Posted January 22, 2021 One thing I can't seem to find is when the factory blade is angled what is the clearance from the front and rear tires to the blade in both directions. Share this post Link to post Share on other sites
Skipper 1,788 #14 Posted January 22, 2021 (edited) A guess would be somewhere close to a 30 deg. angle. Edited January 22, 2021 by Skipper 2 Share this post Link to post Share on other sites

Skipper 1,788 #16 Posted January 22, 2021 I got a nice 50" laying here, if you need some measurements etc. 1 Share this post Link to post Share on other sites
Raposo 530 #17 Posted January 22, 2021 Also, what is every doing for replacement cutting edges for the dozer blades? I would like to add a slightly thicker and taller one to this mid mount i'm building. Just get some flat stock and drill it out? 1 Share this post Link to post Share on other sites
Skipper 1,788 #18 Posted January 22, 2021 (edited) Yes. Or if you want it more durable, you could go stainless or take it to the max and use hardox. That you might want to order with the holes in though. Personally I would go stainless. Plenty strong, and will stay nice to look at.

ebinmaine 67,310 #19 Posted January 22, 2021 Older factory mid-mount grader blades like what I have do not have a cutting edge. I'd absolutely recommend the flat stock. The entire blade is able to be flipped but that's the only chance you get until you add something yourself 1 Share this post Link to post Share on other sites

8ntruck 6,991 #21 Posted January 22, 2021 I'd look at some 4140 pre hard steel for a cutting edge. It wears well, but is still machineable. Another choice would be some abrasion resistant steel. Much harder to drill and cut than the 4140 pre hard, though. Both of these should be available in bar stock from suitable for a cutting edge. Share this post Link to post Share on other sites

I had a 50” mid mount grader blade at one time and it did not have a cutting edge. However, the blade itself was probably 3:/8” inch thick so it was much heavier than a dozer blade.

Raposo 530 #23 Posted January 23, 2021 Cut a large section out of the plow a frame and saved the rear section that has the reinforcements. That is what I’m going to use to mount to the rear plow frame. Next up is fit it under the tractor 2 Share this post Link to post Share on other sites
Raposo 530 #24 Posted January 23, 2021 This is roughly where it will sit under the tractor (obviously higher, it’s just sitting on the floor) You can see the diagonal line drawn on the card board will be the blade when it’s angled. I kept the same 21” dimension from the axle mount to the pivot pin found on the factory mid mount blade. 2 Share this post Link to post Share on other sites
Raposo 530 #25 Posted January 23, 2021 This sharpie line is about 7” tall. That is what I’m planning to cut the blade down to. Then I will run a piece of 1.5” square tube steel on top of the blade to box it in and stiffen it up. 3 1 Share this post Link to post Share on other sites
