I discovered a buried t-post on a piece of land that I own in southern New Mexico. It is in an area where I want to expand the driveway into the propery and needs to be removed or othewise dealt with. It has about 10-inches of the post above ground and an unknown amount buried.
The ground is unbelievably hard. It is a mixture of small flake rocks from decomposed sandstone, some fines (sand and soil), and probably 25% caliche clay. The ground is nearly impossible to penetrate - I have NO idea how someone got the t-post in as far as it is. For example, we were putting in some geotextile and had to use rebar to make holes for the pins. It took about 30-40 full hits with a 3 pound hammer on the rebar to drive it 6-inches into the ground....we put in about 250 pins.....
For the t-post I tried: pushing it back and forth with my tractor using the bucket to loosen it - didn't budge just bent the post. Lifting up on the post using the bucket - didn't move. Pulling it out with my F350 4x4 in 4wd low range - didn't budge it an inch.
My next thought is to use my 10-ton porta-power to try and lift it straight up - or, lastly - dig around it with the back hoe and cut it off 10 or so inches below ground.
Any other ideas?
