How we got the JCB!!
The tractor moved along an absolutely dry road, not in the lowland, not along a swamp, but still fell into a small “water lens” under a layer of dry earth. To get out of the way the muddy generator belt, which also turns the pump and the lack of possibility to help yourself hydraulics, interfered to get out of the way, for when trying to raise an arrow or frontal head, the tractor simply sank. Thanks to all the participants.
