I think I'd look for a place to put up a walk through gate.
That gate is big enough to move equipment through, so for less than 50 bucks you could buy a 36" or 42" walk through gate and put it up in a better place, maybe 50 yards down on higher ground.
Or, in other words, you'll spend more money trying to fix that than to put up a new gate. Leave that one where it is.
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
