Oops… Dang!

I was recruited to assist with undoing this unfortunate mishap.
My friend went to get a hydraulic jack and a piece of heavy lumber, while I guarded the mired rig.
We managed to jack up the bed of the trailer enough to get a wooden beam under the wheel.
Once the wheel was up on the ramp, even with the load still aboard, the tractor easily pulled the trailer out of the lake.

No harm done and we had a bit fun repairing the situation.
