  My 7020 gas passer swap is great but as the experts here suggested it can be better with a tractor governor.
   Can anyone give me an idea of what parts are necessary to swap ? It looks like the parts are mostly external so no major surgery needed.
    Maybe a photo?

The governor weights inside are different between tractor and combine. You need all the tractor internal and external parts to do this.

It's not a bad job at all. You just need a donor engine for the parts.

The difference is how the governor is designed to operate.

The combine power unit is intended to run the combine at a preset constant speed... it has a low-idle position, but when time to operate, it runs at that preset speed, not 'somewhere in-between.

The tractor engine is intended to be variable in it's speed setting... any point between low idle, and full speed.

The combine governor in a tractor application will work, but it will NOT be particularly stable at any point other than full governed speed.  It will be VERY stable at that speed... meaning... a very slight change in load will be responded to.

The variable governor of a tractor allows choosing the setpoint, but in doing so, sacrifices sensitivity and accuracy.

The constant speed governor of a power unit sacrifices adjustability for sensitivity and accuracy.
Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest.

So governor parts from a 190XT’s G2800 301 only?
What about the G2500’s governor parts used in either the 180gas or 190gas ??

180-190-190XT all the same parts. 180 might have a weaker spring.

I would not put up with a combine gov in a tractor! You may not find one close but there has to be plenty in salvage in the states. It can't be that cost prohibitive.
