Just finished fabricating a backdrag edge for my Fisher Plow.

wrightway---may sound a lil stupid but even at the same angle, it cleans much better because the backblade is thinner than the front cutting edge and scrapes more. also, the front cutting edge is always flat from all the pushing, the backblade with some time is going to make its own edge and will clean better. i have backdragged without a backblade and then converted to a backblade like the one the OP built and cleans much better than the cutting edge. it may sound stupid but im saying it out of experience, correct me if im wrong.

Back drags like a pro. wont change anything about the design or angle.

[jimcouture]

There are 4 mounts, on 3/4" pins, in which the mounts are welded directly to the back of the trip edge with 10-12" of weld per mount. Muliple that by 4 mounts.....thats 40-48" of weld holding the back blade on. If you have ever used your plow feet, the hiits the ground before the blade does and isn' t attached nearly as well as these backdrag mounts.

It scrapes very well and functions as i need it to.

looks very similar to the one on my old truck, loved it. you will be enjoying yours. as a bonus when pushing gravel you drop your blade, roll forward till plow is on the ground then lift up a tich, now the back drag edge sweeps the gravel and your blade pushes the snow. also sweeps curbs clean as you lift over them.

So I was having a guy make me one just like this and he says he cant weld to the edge he took off my front to use as a backblade because it is hardened steel and you cant weld to it. Others have, what is the secret to welding brackets to hardened steel so they dont break off.

[chevyzrule810]

Heat it up with a torch before you weld it.This will weaken the steel and make it brittle and it could break like the one below.

I under stand what your saying I did not think about it being ground to a knife edge
But I still think adding some stops and standing it up more will help it not climb over the hard packed snow

looks great. hopefully it works well for you

Did you by any chance make Print

Nice lookin' blade you've got there. I put an oem back drag blade on my Western 8' Pro. Added about 70 lbs and took $90.00 out of my pocket. Works ok but not great.
