Always in search of realism, here is a light mod that will require you an extra effort to harness your equipment, since it will have to be done by hand. Finished pressing A to attach all of a sudden, it is now necessary to couple the 3 points then the PTO, in which case your tool will not be functional. Be careful, however, in rare cases, the mod crashes the game (nothing bad, just the game does not start.).
In the opposite direction, to unhitch, you will have to remove the power take-off and then detach the tool. Note that the hydraulics remain automatic. Colored markers help you spot hitch triggers. Finally, a key on "Left Shift + Q" allows you to switch between manual mode and the original automatic mode.
