You could get a roll of 12/2 G or 10/2 G UF copper cable and run that. Better conductance than extension cords.
There are problems with that arrangement. It would deny the opportunity to put up and put down cords every time I mow. It would make fencing less vulnerable to overloading outlet during storms. It would be smart. Some things simply are not to be on my little farm.
I will be on that likely next year. Really pondering photovoltaic charger to run barn ventilation and lighting. The micro-scale aquaculture could be powered off that. Night flying insects have some serious potential almost 8 months of the year. During half that, temperature too low for fish consumption to keep up.
Insect drift I have really been aware as very significant protein source for my free-range juvenile chickens.
