Glueing pot metal ???????

I have a toy tractor that some how has gotten broken in half. Is there a glue, epoxy, or J B Weld that will work to put this back together. It will just set on a shelf for display & will not be played with. Thanks for any info.
 
What kind of break? Along the seam or fell off a shelf and broke kind of thing?

If its a rough break, where you can see the pores of the metal, I have had great luck with JB Weld. I even glued a barrel on an air gun with KwikWeld. KwikWeld is a little weaker mix than regular JB Weld but the Quik will come loose at 300 degrees. Its comforting to know that if you screw it up, you can take off the meltable stuff, put it in the oven and everything releases just fine.
 
Can you drill a couple deep holes in each half, stick a wire in, and use JB weld on the wire, in the hole, and split halves, to hold it together? BTDT with small stuff.
 
You don't say what kind of toy tractor, but you should have no problems glueing it back together. If it was me, I would try to work some wire or headless nails into the joint for extra strength. I would use JB weld. Its easy (comparatively easy) to sand off the excess before you repaint it.
 
I've successfully used JB Weld on a couple of pot metal carburetor parts over the years where ears had snapped off bolt hole bosses due to careless tightening by previous owners. Cleaned them well, made up a clamping fixture out of a piece of flat scrap metal to hold everything true, "V"'d out the crack a bit to get more grip area, let everything dry for a couple days to ensure a full cure, took extra care in reassembly, and they've held up fine. Didn't have much to lose, as the equipment had been scrapped anyway and new parts were either unavailable or cost far more than I'd paid for the whole machine.
