changed the flipperIJ Did u rebuild or replace the yoke that bar on the hydro pump is moved byIJ Both the bar and the yoke need to be in good shape to maintain speed. Could be your cable is tretching smoehow too.
I had a combine like yours and mine did the same thing.I found that on top of the hydro pump where the cable from the cab hooks up,at this point you will find a small flat piece of steel.This piece fits through a fork like piece. I find that there is usually causing you slower speeds. I hope this is somewhat clear. At least check this before tearing into hydro.GOOD lUCK!
