Well, pulled the trigger; made the deal on a new 9 ton Wacker Neuson. They delivered it on Wednesday, and took my 420D back with them, Sad to see it go, it was a great machine, but looking forward to bigger and better things (I hope!) with the ET-90. Been practicing: digging out snow banks and picking scrap steel out of the recycle trailer with the nifty hydraulic thumb. About all we can do right now as everything is frozen solid with about 4 feet of snow on the level.
Also nifty is the hydraulic pin grabber. Thanks for the advice guys.
