That is REALLY cheap as far as parts go. Any reasonably good welder can make that BETTER then new.

Way better than new. That looks like a typical cold weld. Even a hack welder like me can do a better job than that.

Looks to me as an excuse to buy a welder.

It would be an excuse for me to buy a new tractor! (LOL)

Broke a hanger bracket on my 6' MMM....... B3200 has 400 hours & most of that is mowing, so who knows how I managed to break a weld on steel plate. Dealer wants $120 for a new bracket & of course they'd have to order it...... I think I'll see if it can be re-welded.......

Sand blast both pieces and assume that all the welds need to be beefed up.

Did the base metal shear right off? It's hard to tell from the photo if the break is "ball in cup" or base metal brittle shear/fracture.

If its the first break type, re-welding will be no problem.

The second is indicating a whole different problem and you will need to be extra careful with pre&post heat when re-welding. I suspect this bracket isn't plain old mild steel.

There are 2 breaks there:
1. The side brace (going roughly left to right on the piece that is flat on the truck bed in the picture, both sides are rusty) had no penetration and broke a while ago.
2. The main weld (going roughly up and down on the piece that is flat on the truck bed in the picture, both sides are shiny) broke just outside the heat affected zone from the weld due to the side to side flexing caused by the lack of support from the side brace.

I would never expect anything other than A36 grade mild steel in any farm equipment. Alloy metals are reserved for critical things like roll bars on racing cars.
The reason for breaking is typical of MIG welds that are improperly done, lack of penetration and cold lap.

I would definitely grind and repair the other weld while working on the broke one. It is likely of the same quality. I would grind off one side completely, reweld, then grind off the other side completely and reweld it also. Then you can put some of that expensive Kubota orange paint on and reasonably expect it to never break again.

Yep. We see this all the time. Never properly welded in the first place. MIG guns are NOT hot glue guns. To weld means to penetrate the parent metal and liquefy it also. Not just stick hot cream up against it.

I broke a weld on the deck wheel mount on my Kubota MMM. I just ground it clean and re-welded it (Arc) and sprayed it orange. Doubt I had more than an hour in it from start to finish and the metal was just normal mild steel. I won't expect yours in any different there.
