Combines new header problen on K2

I would almost bet on a dirty hyd filter. They go quickly when they go a the small machines. If not filter then check the belt driving the hyd pump. If that belt gets just a touch loose things don't happen. I push a 4-38" head around with a K2 and believe me that filter has to be clean and belt tight. A K2 should waddle through 3-30"ers like there is nothing there.

Thanks alot, I had forgot about the hyd. filter. I'll change it out and see what happens. Again, thanks for the reminder.
