Drill a small hole at the end of each crack first. Prevents the crack from spreading

Yes, and V out the crack some with your angle grinder wheel so your bead gets down a little deeper.

got it, easy to do, like cleaning out a tooth cavity...

I really don't have to be a perfectionist here because whoever who used this deck before just brutalized it.
This will be a showpiece frankly, there aren't many Gravely wing mowers out there. And I have two...
now for a seriously cool project, I'd like to weld/fab/build a custom towing bracket and have a 50 plus 2 40 inch wing mowers
all going at once. Maybe....but always wanted to take that to my local Grange Fair.
I have almost eight acres of lawn and short fields; I could actually use a big mower like that in a few areas.
Whoever owned this before must have hit every tree on his property every week.

drill and edge grind, I can do that. thanks

I have finished making the new metal to cover the holes and add strength. Not trying to be exact original but not too far off. Will look like a fabbed deck...all the rage right?
what rods would you all recommend for the cracks and for welding this metal to the not perfectly clean metal underneath? Plus I'm sure I have to put some tack welds in the middle; two pieces of flat metal on top of each other. I will have them clamped tightly for sure. Never done this before so suggestions welcome.

I do have one more cut to make on that one long piece, odd angle.

weld both sides of the crack and as said drill 1/8 holes at the ends of the cracks if you just put a plate on top and not weld underneath moisture will rot underneath your doubler plate after welding bottom grind smooth so as clippings don't stack up on the weld.

I'm not a stick welder but easy rod for this job could be 6013. Although any type rod will work fine. Everyone has their favorite. Run a couple beads with several types and find your favorite for this application.

If the metal you are using to patch with is galvanize drink milk or eat ice cream after your finished helps to seatle your gut

While I have heard that advice several times to combat the zinc poisoning from welding galvanized steel, I think an even better advice when and if you absolutely have to weld galvanized metal is to weld it outside, and keep a fan blowing the smoke away and make sure your head is not in the smoke plume.
The very few times I have had to weld galvanized steel, I have used a fan outdoors, and seem to totally avoid the "fume fever" from welding such metal.

If you can avoid welding galvanized metal you can avoid the problem, if you cannot avoid it, then avoid the smoke, and I guess if you get sick, try the milk.

For mild steel I 2nd the idea of pretty much anything. I would use whatever you have on hand and like to run, 6010, 6011, 6013, 7014, 7018, 7018ac, 309, 316, 316L, 99ni...for me, that's usually 7014.

I would second the motion that the 7014 is hard to beat for filling holes and cracks, It is a high deposition rate and seems to me to "wet out" better than some. In any case it is what I grab when wanting to fill a hole. Although anything could be used.
