Why this is the answer
The correct answer in the official bank: On a leveled surface, to prevent accidental movements.
Tools and trailers should be detached from a tractor on level ground. On a slope, the moment they are released they can roll or shift on their own, tip over, or crush someone nearby. What matters is that the ground is flat, not whether it is concrete or asphalt, so not just any spot is acceptable.
