FAHR M600 combine

The original is believed to be a giants mod from FS15 converted

The original Fahr M600 combine had a bug in the positioning of the header

On perfectly flat ground like Goldcrest you dont see any problems with
the original but with uneven or rolling fields like Altenstein field
#2 the header goes so low it lifts the drive wheels off the ground

I have adjusted the header lower angle by 5 degrees so this no longer happens
