@EvilSandmich @sickburnbro Gayk, a German company which is really the only pile driver manufacturer of note makes less than 50 machines a year and you have to get a on a waiting list about two years out if you want one. This is for solar fields, but I have a friend that ran a solar pile driving company that was telling me how impossible it is to get a machine (even a used one) of this type.

I imagine other large equipment is similar.
