We decided to put in a zip line on the upper field, not a long one just about 160 feet. I figured on 4 foot hole for the posts. I’ve dug many 3 ft square 3-4 ft deep hole for trees over the years so I figured 2 stupid 12” x4ft holes no problem...broke out the one man gas powered auger and fought all the way to about 30” then said screw this.. with a bit more colorful language, went to tractor supply and bought a 3 point auger with a 12”x48” auger bit.. when I got it home I uncreated and assembled it, fought with it to get it attached then eagerly drove down to my waiting hole to dig the final 18ish inches... and promptly got the f-ing thing stuck. So tomorrow morning I will be digging it out... any advice from those who have experienced this would be greatly appreciated!
