Then I tried the 6 minute set JB weld, that held about a week then started leaking again and the JB weld peeled off.

About a week ago, I took the tank off again. Cleaned it really well with dish soap and water, then "plastic welded" it a little with the soldering iron, then sanded it with some sand paper, then wiped it with acetone, then put two coats of JB weld on it. So far, it's been holding. I was trying to avoid buying a $75 replacement gas tank if I could.

I agree, sure I could just go buy another tank, but it would be much cheaper to fix it!
Thanks for the info Guys

I've used permatex "plastic tank repair kit" with great luck in the past. You can find it at any auto parts store. Comes with everything you need including sand paper and patch.

It does say not reccomended for fuel tanks but it has worked well for me

I have used JB weld in the past, lastedfor awhile but peeled off. Then I found the Seal All at Oreillys, and it works.

Yeah crazy the pitchfork fell off its hook and wedged itstelf in the side pass door well. It then worked its way down the side of the tank until the last tine punctured the tank.

How in the heck could the weight of a pitch fork stab through a hard plastic fuel tank? The only way I could see that happening is if the mower was not secured and it bounced around and hit the pitch fork. Always keep mowers secured regardless of open or enclosed trailer.
