Used my GC1710 to trench between two buildings. Dug from the edge of one building to the center. Then turned around and did the same with the second building. That left the tractor as a helpless orphan straddling the 2 foot deep trench with no way out.
Finally used some 4x4's, 3/4 plywood, the front hydro and the backhoe to drive/lift/push the tractor back to driveable land.
