Default Homemade Suburban mid mount grader blade

I've been eyeballing the owner's manuals for the original mid mounts for some time now. No matter how long I stare at the pictures one never appears in the garage so...
I'm going to use a rusted out 46" dozer blade and a bunch of salvaged steel to build my own mid-mount grader blade to fit my ST/12.

4 weeks ago I pulled the dozer blade from the lean-to and cut it half.


A few weeks back I removed the skin from the top half of the blade. ( I'll use this to skin the new blade. I also cut off the remaining curved sections from the top rib to use for added support for the remaining blade.

This morning I cut up a few chunks of 1/4" plate to approximate the original mounting tabs. I used 1/2" bar and 2 washers to make the upper locating pins. I'll dress up the brackets a bit once the build is further along.
Only one is pictured, but both mounts are done and on.




I'm planing to use the remains of the tongue jack in the last 2 pics for this build as well.

I'm going to be busier than I'd like with other things for the next week or so, but I'll post updates as often as possible. I can already see the ground piling up in front of this thing. I can't wait.

Those brackets you made look really close to factory.

Thanks Guys. The brackets will look even closer to factory when I'm done. I didn't want to put too much time into them in case I scrapped them for something else before the project was finished.

What's the advantage of a mid-mount blade, or is it just cool?

The factory Mid Mount allowed you to not only angle side to side, but grade on an angle like a regular road grader did. They look cool, and work well, the only disadvantage I had with mine was that the lift mechanism got hung up when I was driving over rocks and or sticks etc.

I have been thinking about making one recently as well after I traded mine, but a much more simple design, and maybe something that the lift would tuck up into the frame.

I can't wait to see your progress!!

Supposedly easier to do a nice job too because of being between the wheels. With a back blade, if the front wheels go up a slight rise, then the back blade goes down, digging a low spot, so you have to control it with the 3 point handle.
That and as James mentioned, the ability to crown a drive. They adjust for more or less crown.

Tractor#2- I've always thought that you could get a more even grade between the axles than in front of/behind. I'm also building it for the cool factor, for more welding experience, using up scrap that I've amassed before we move this summer.

James- you bring up a good point about sticking in the up position. I'll have to ponder that one for a bit. Was there anything else that you would have changed given the chance? Eventually I want to add a couple of linear actuators for lift/downforce and blade angle. I'll still tilt the blade by hand I think... Unless...

Keith- Let's see how #0001 goes first.

I should have a few new pics tomorrow.

The model I have has a lift handle like the mower decks. They are made to spread stone or dirt, not grade hard packed ground. You can set the height unlike the rear grader with a manual hitch. The blade is also 1/2 thick steel unlike the graders.

Like most of the other attachments, you should take it off if it's not being used. The brackets say on.

I used the eathcavator with the elec. hitch today. That works nice as you can feather the switch to set the height while your moving.

I've used all three and the midmount is much nicer to use for grading than the rear or the front. It is much more consistent between the axles than 2 or 3feet infront or behind the axle, if you hit a hole with a front tire the rear blade goes way up because it is so far away from the axle. It also makes for a shorter rig wich makes it easier to manuver. The rear blade is better for pulling material away from an obsruction, like pulling snow away from a garage door, and the front blade is better for clearing snow. So if you could only have 1 the front blade can do it all but for grading the midmount is far superior. On my mid mount blade I can push down with my feet on either side to take a bigger bite of the material. Ed

ive always thought that an easy way to make a midmount would be to make a reverse A-frame, with the double end on the lower holes of the front axle. on the single end, you have the blade, then an electric actuator to lift and lower it.

i like your work so far jake, ill be interested to see how it works out, i might put in an order for number 00003

I got about 2 1/2hrs in today. I'm happy with the progress considering I'm working with hand tools and each one of these pieces is cut from a 4'x6"x1/4" plate.





All of the holes line up so it'll hang straight without pin bind.



The outer bars keep the blade frame stable and square to the tractor. The framework that locates the lift mechanism will attach to them as well. The inner bars will reinforce the connection to the "C" frame that will attach to the blade pivot tube.



The more I look at it the more I don't like the ears that attach to the tractor frame. I feel that 1-1/4"x1/4" tabs will bend if the blade gets hung up on something. I'm debating constructing stronger tabs.

Tomorrow I'll start constructing the frame that the blade pivot tube will attach to.

I've just started restoring a Pennsylvania tow behind 3 gang reel mower for my Custom 6 so you'll see a thread start for that soon. I'm also waiting for an electric assist 3pt hitch plate to arrive as well- yet another project I want to get started on. See ADD can be a good thing- sometimes...
