I have had a wheeled Drott 40 for years. Mine was setup originally as a feller buncher? Then it was a county machine cleaning ditches, it has a tilt wrist. It has so many pedals, switchs, I have to look at the diagram every time I run it. We had an old timer that could run like he was born in it and he broke everything including the extenda boom. No lights no heat stuck in second high patched up boom and outriggers etc etc. We have not had the bucket on it in years, we use it as a crane. If its moving I think its gonna tip I hate running it. On the other hand it always starts, 4 weeks a year I run it 10 hrs a day and it does the job. Around here we like old Detroits... but you have to like fixing crap! We put an additional counterweight on it and drive it around on two wheels, it has crazy power. Dig a pond no sweat, 9500 no way! As far as scrap goes the counterweight is concrete.
