Pics of what you have would be the only way to give any really good advice. The best advice so far is to remove the broken piece and have a few inches shorter spear. But by what you've said there is a possibility that a weld would hold. To break that straight it is certainly hardened steel, but impossible to tell exactly what. If you weld it use 7018 on dc or 7018ac for an ac welder. I don't like to weld around something like that so I would grind it flat from the sides so the weld was vertical when the spear is installed. Leave about 1/4 inch of flat in the middle to weld against. I usually paint a line down the middle, fit the pieces together so the line transfers, then grind to the line. That way the pieces will match after it's ground. Start welding by tacking one side, then weld a good weld on the other side. Then grind out the tacked side enough to ensure 100% penetration. Then weld that side some, switching from side to side til done. No need to try to clamp it to something for straightness because it will pull back and forth as you weld it. Just lay it on something flat and start it as straight as you can, doing a final straitening after the first 2 welds. As you weld watch for pulling and weld the long side to pull it back straight. When done allow it to cool slowly. You can drape a blanket or leather over it to slow the cooling. Don't pour sand or anything like that on it tho. That will give you about as good a weld as you will get without gusseting of some sort. If you could gusset it for a few inches that would make a better than new repair and wouldn't likely interfear with the bales on that end. Good luck with what ever you choose. Just cuz I'm curious, did you look at the break to see if it was all new or was it cracked before. I'm suspicious that what you did would break a good spear.
