next IRL example :
This picture comes from "tony167" (forum.grostracteurspassion.com)
The road is slightly wet, and the John Deere can't move anymore.
As you can see, the slope gradient doesn't seem very steep.
This has nothing to do with Hagensted (nothing to compare with the ingame raod gradient), but still, the tractor can't make it
Of course, the road is "steeper" than what we think it is by looking at the picture.
example for those who think a tractor should keep its speed for a longer time before losing speed (inertia) :
Watch this video from 4:50 to 5:402012 Grain Harvest Dalmeny Estate Scotland
Please note the trailer is far from being fully loaded (less than 10T of canola). And as usual, the slope gradient is not at the same level as what we can encounter ingame.
