Unfortunately they all had some type of herbicide in them. Most of them have just resisual in them. Few have more than five gallons in them. Still deciding what to do with that. I can tell you what, a tractor couldn't come soon enough. Pulling those things off the trailer and stacking them on top of one another wore me out.
damm that sucks. Well you if you can find a way to dump it and clean it safely you might be able to sell them. Did you do the rolling-end-over-end method to move them? Why did you stack them on top of each other?
End over end and some dragging. I dont have a logical answer for why I stacked them. I suppose to minimize space usage? Thats the best I can come with.
Looks like you got plenty of space over there. Good luck with the new tractor! I would absolutely love to have a tractor but that's not going to happen unless I move.
Look on the bright side. You won't need to buy any weedkiller for a while! Decant it into five gallon jugs. Just check the safety data info before using it and don't expose yourself to anything nasty. Or post pictures of the IBC labels here and I'm sure the members will tell you what you've got or help research it.
That's exactly what I do. 3 lag bolts down the center through the bottom into a pallet, top already cut off to cover wood stacked in the IBC cages. Drill holes in the sides to your heart's content. One bladder holds lots of shorts and uglies.
