I cut probably 30’ of wire off close to the stump. Wire in the wood gets ground, wire on the ground wraps around the axle and isn’t ideal.
A fence post in wood isn’t fun to grind, but it isn’t the end of the world, usually. Thicker metal becomes a problem pretty quickly.
I left the stumps tall to keep from running the saw into metal. The stumps were cut last year, same as that tall pine stump. Until I ground the pine stump, I figured I was going to have to bite the bullet on cutting the wire/metal, but after the pine I figured I’d give it a shot.
I didn’t grind the stumps very deep, there’s a 100 pair phone line under them that I dug up once before (locate didn’t mark it).
