Hi Guys,
I'm sure this is a very simple ID for most. I picked up stump a few months ago with no info.
Vigorous grower with large leaves.
Hope the pictures help shed some light.
Thanks

reminds me of some sort of maple

Try Acer negundo. It is a very tough but quite a weedy maple and self seeds all over the place. Relatively large 3 lobed leaves.

Thanks Shibui,
A quick google image search and looks like your right on the money.
