That machine is out of spec on the high side.. Not sure what to make of that. That's would line up with the average of 2500 I was trying to remember for what my machine was putting out. That's a huge jump from 382 to 1000 and only 2 gpm difference.
I don't see how 8.6 hp grinds up 12" logs though. :}
