Combine not working with corn header like it should

[Howfarmswork]

https://youtu.be/ZUfDdx58g48 This is a video I uploaded showcasing the case international 1660 (or case ih 1660) combine using the capello Diamant HS8 trying to harvest up hill on ravenport on the northeast side of field six, I’m in need of help in trying to figure out why it doesn’t seem to want to reverse or go forwards. Please someone help me with this problem that would be much appreciated. Thank you.

The combine does not have enough power to run that large a header. Unlike FS17 where you can run large headers on small combines FS19 you need the appropriate header for the machine. Use the smallest corn header for the Case 1660.
