Well, I decided to build myself a rear grader blade like the one i built for Hugh, with a few small changes. I learned from the last one, and hopefully I have better steel this time so the pivot rod doesn't bend the first time it gets used.

Here is what I have done so far- cut the tank (plow will be 36" long 12 1/2 inches high) welded some 3/4 x 3/4 angle on the top for rigidity, and near the bottom on the back, and installed the cutting edge on the bottom.

You don't think the steel is too thin? I cut an old water pump up into a BBQ pit, and it just seems too thin for dirt work. My rear grader blade is 1/4".

Hugh used his succesfully for a while and the tank did not bend at all. The steel is 1/8" but it is very strong as it was an air tank and had to hold over 150 psi of air. I guess we'll find out :) Hugh build is HERE

Well if it works, I may be cutting up my BBQ!

Thinking of changing the design a little on this one... I saw this
box blade idea.JPG
Agri-fab box blade and i am going to model mine after theirs. should be sweet- the ends will be removeable, and i will make my scarfier adjustable.

Better yet, I may make two of these--- One like a gannon, and one just a rear blade!! I have some good ideas on how to make a Gannon type!!!!! I would still have to get off the tractor to roll it over, but it wouldn't bother me!!!

More pictures!!! I decided to go a different route with this one- I was going to cut the tool bar up and weld it so it looked like the 3 point mount that I made for Hugh but i decided it would be bad to cut up an actual sears part. So i drilled a few holes in it, mounted these brackets I had lying around, and decided to make it more like the box blade. I will make the pivot mounted on the back of the frame, and drill some holes in the ends of the blade so i can bolt ends on it, and or extend it to make it wider. I will save the "james"-cavator for my next project :)

So here you go...

I made this mount a little stronger than the last one... I used a 3/4" steering shaft from my partially stripped SS16 and welded that to the supports on the plow, and welded it right to the plow as well. I decided that I will weld the plow pivot to the pivot plate on this one too. Don't know if anyone has seen the blade on vintagesearsgarden tractors, but I want the pivot to be like his, but again, I want it to be more like a box blade.

Looking good James!

Just a thought for you, i have a harbor freight powder coat gun. If you were to powder coat your plow and parts they will last a lot longer ( and look cool too!)
I would let you use it if you want to. On smaller parts I have used a torpedo heater to cure the powder but for the plow you might get away with that, or you could use one of the curing lamps they have.

Thats an idea! I will let you know! I may just spray it with Rustoleum Almond- I have a couple quarts of that.

Let me challenge everybody's fabrication skills,,,, I want a grader that will allow me to do this: Drive across the slope of a hill ( about 7 degree slope ) with a grader that will grade level: as it I am creating a flat path to drive on..
and to make it more challenging: place some sensors on the blade along with a actuator that will, as the mower leans left and right, keep the blade level..

I have a few ideas in my head,, I will put them to paper later

well the angling is easy- you just need a pipe that rotates the mount of the plow vertically end to end (my mid mount was set up like that) and you could probably use ride height sensors from a Lincoln Mark 8 or similar car to accomplish the leveling feature

this thing is gonna be pretty heavy, and the platform on th back allows for a weight box or cinder blocks as well.

To make it a box blade, I am simply going to add some 90 degree brackets to the ends of the blade, and bolt a flat piece of steel to those.
