Interesting I thought machines mostly used electric actuated valves, any particular reason this one uses hydraulic pilot?

With such a new type of excavator larger than 150, I don't think there will be any problems other than maintenance

why does doosan run Perkins engines, literally buying engines from cat to put in there own digger would be like a Scania with a Volvo engine
