I mean lifting the front wheels of the Terratrac when the model steers. But I agree that lifting the header will require quite some force.
A lexion terratrac does not have that feature it’s to heavy, a forage harvester have the same weight the hole time, a combine can have up to 18000 L (13 T) in the grain Bunker, plus it’s own weight, which is, depending on header, over 20 T,
