(ET) Putting a back-hoe on an E20

[Chris Zach <cz alembic crystel com>]

So I was thinking: After spending a few hours working with an excavator 
in Vegas (dig this, lot of fun) I realized that what I really need on my 
E20 isn't a front-end loader, but an excavator arm with a thumb.

So.... Anyone ever thought about this one? I'm thinking mount it on the 
back swap the seat 180 degrees, and run the hydraulics off an E20 sized 
motor. That would reduce the pressure on the front wheels, how much 
weight can the rear of the tractor take?
