KOMATSU D155AX- 6 Vs. Cat D8R

I'm sure the operators will be willing to switch seats in the name of science. Might be a few months before I can give you guys a clear account, but I'll be sure to fill you in once we know for sure (in a new thread). In the meantime, anyone care to weigh in on a similar question? This time with a KOMATSU D155AX-6 w/ outfitted with a single shank adjustable ripper vs. the D9G detailed above? Thanks again! Edit: Side
