I have a single stage, dad had it powered by a gas motor. I made it run off a hydraulic motor. This way my tractor on the swing augar can use the hydraulics to run the grain cleaner. Would a 2 stage be able to do this? How many motors on a 2 stage that also has an augar to send the trash into a wagon? Does a 2 stage clean out fines then the larger crap? Thanks
