Repairable? Back blade pivot

[Tom Bond]

I bought a Deere back blade a while back but I need to repair or replace a few teeth on it if possible. Whatta ya think? Can this be repaired? This part is no longer available from Deere. It's off an old 88. I was thinking just have a machine shop make a whole new top plate with the teeth but you can see it's welded on pretty solid on the bottom as well as the sides. Any ideas if it could be done and what a machine shop might charge to do it? I was also thinking just angle it to where I need it for dragging snow and weld it in place permanently. The plate is 1/2". Thanks!

It must have caught on something pretty rigid and had some HP in front of it to damage it like that!

I would cut out a larger area and weld in a new piece of steel, then shape and notch it to match.

You need a fabricator not a machinist. I see no problem with torching the two broken teeth off and welding new pieces on. Take an
angle grinder and clean it up and you're back to work in half an hour.

I agree with wore out, use the opposite side to draw a template, transfer it to a new plate, and replace the complete damaged end.

I would not weld it in one position.

As I suggested before when you were asking about this, Take it to a machine shop. Let them look at it and see what they say. They might see a different way to meet your need. Maybe get rid of the bent teeth, cut a new plate and mount it on top of that one, might need longer bolts/pins if that is done. Maybe they think they can redo the teeth and reinforce underneath. Maybe just replace that side with a thicker plate, so as to weld it to the frame on the underside as well as making a flat top. Prices vary, so what I think it will cost at a machine shop means nothing. You need a quote(s) from the place(s) you might take it to, WAGs from all over the country. When I say machine shop I mean a fabrication/machine shop not a straight machine shop.

I agree with Randy. That would not be hard to fix.

That's a pretty easy fix, since you have one undamaged side as a template. Cut a curved piece of 1/2 based on the good side, so it will clear the lower structure on the inside of the curve, and matches the outside curve of the good side. Use a drill to cut the bottom of the slots, and a hacksaw for the sides of the slots (or a torch or plasma cutter). Scribe the inside line of your new plate on the damaged side, cut along the line, chamfer the new piece on both top and bottom and weld it in place. Grind it back to flat on the top and bolt it back together. steve

Use the good side as a pattern. But before cutting away the bad side teeth, use some angle irons etc.
bolted to the good outer slots on both sides to make a fit up jig that will hold the new replacement side
in the proper place.
Trace a template with a scratch awl onto a hunk of plywood.
Then from the outside of the weldment, cut the 1/2 inch plate free from the rest of the plate.
Have a fab shop or your steel supply plasma or waterjet cut a new profile to replace what was cut off.

Then butt weld the new to the old using the jig to get the new piece in the right spot.

This way your not cutting any of the old plate away from what it is welded to, you only have to butt weld
the new section of plate to the old plate.

A machine shop can make that better then new . With the
price of everything the way it is now I dont know what it might
cost 2 or 300$ maybe but who knows until they look at it

Talk to a fab shop and have a burnout made that matches the current plate. Fasten the new plate to the bottom of the
existing plate and rework the blade so that it will work with the doubled up plates.
