Well here is my first attempt at a back blade. All I did is take an old tractors front blade and reverse how the push tube attaches. Welded on a trailer coupler ( upside down ). Drilled a hole through the coupler and pinned it so that I would have up and down, but it would not rotate on the ball. It will also be able to detach and then I can use the winch system for something else or just as a winch. Where the cable runs across the top two bolts there is now a pulley and where the hook attaches to the blade there is an eyebolt. Pretty much all I have to do now is paint it. One thing I do need to do is figure out someway of getting a little down pressure. Put a weight on it ?? Car shock absorber ? I also need to figure out a way to make a quick disconnect for the winch wires. Then I can transfer it to the tractor or 4 wheeler easily ( yes, I do have a 2" receiver on the tractor !! ).
