Those tractors look really good! Detailed!!
My best regards, Kodiak.
Now needless to say these are not the default tractors but mods I have downloaded which are by far more realistic.
Interior of the New Holland tractor...
Climbing in from ground

Front Panel

Right Panel
And if you hit the space bar many of those interior controls work by clicking on them and do what they are supposed to.
And as you use the tractor it gets dirtier and dirtier and you can then bring it back to the farm and use a power washer o it to clean it up.Also as it gets used you have to change the oil after a certain amount of time used.
Not all mods go into this level of use and detail but most are much better than the stock equipment.
