my friend said he had figured it out, but i didnt try the fix myself. he said that certain components of the vehicle weigh too much in the XML, so he adjusted the weights and got it working well. i dont know which components he adjusted, but that info might be a start.
Hey idk if you got it figured out or not or moved onto FS25 but pretty much what onehellofasandwich said. The mass on the components for the carriage need to be lowered. That'll be found in the XML for the carriage not the main machine.
