It was submitted to the modhub....ask Giants Software why they won't release it.
I checked the xml, it is automatic:
<transmission autoGearChangeTime="1" gearChangeTime="0.4" name="$l10n_info_transmission_automatic" axleRatio="8" startGearThreshold="0.1">
Mygamesteam will take a look at this, but overall this tractor is not designed to lift heavy items via the 3point.
If the models you mentioned are not physically smaller then the 190, and it's just engine/horsepower changes...then yes, easy to add. Would require decal changes as well.
Done
UK vehicle, right hand drive
What is it?...new or older model of the 3200 tigre ?
