Yes videos can be misleading. No question. I think the point that I am trying to convey is that in this case, the video does reflect actual use.
The Deutz engines are rated to 45 degrees. Not a dry a sump. I believe that it is done with a larger than typical oil pan. The engines are technically oil cooled, so they have relatively more oil. Only the model 1850 is rated to 45 degrees, while the other models are 25-40 degrees, some limited by the engine, some by the HP and center of gravity.
In the EU, Aebi makes a machine for similar uses.
All the best,
