Having trouble with engine load in tough wheat, seems like the combine is grunting and struggling 30ft. swath lots of straw engine load is at 100 plus going only 2 m.p.h?
Any help would be greatly appreciated

concave 1/4
fan speed 930

Straw is tough

Could your front end of rotors be wore out and bottle necking the system? I assume it is slug feeding more than your other combine. I have had dirt in throat of combine before that needed to be cleaned out in order to restore capacity because material was slugging over it. Just some thoughts.

It is not What you know, it is WHO you know that counts! Currency is a UNIT of debt - not value!

Have had a similar thing when the fuel cap got left off and canola pods started to choke off the fuel supply. Changed filters recently?

Turbo Intake hose is collapsing in and you are not at full power.

Get someone up on the platform and look at it when you load down the combine, it is right beside the step up to the grain tank.

Check the hoses and clamps at each end of the pipe from the turbo to intercooler are ok. I have had a broken clamp and split/torn a hose on our 9080 before. The intercooler to engine side can be checked also but less likely to be a problem there because the aur is lower temp.

Had a 9070 once that the camshaft position sensor had rotated out of place a bit. Engine ran smooth but had no power at all. More likely an air or fuel problem but something to check if those ideas don't pan out.
