I have been working on putting up t-posts for a 4 wire electric fence to contain goats & my LGD. I am fencing about 5 acres, in an "L" shape. One side has very shallow topsoil, with shale about a foot or slightly less down, It's been a real bugger pounding t=posts through the shale. The other half of the pasture has a lot more topsoil, not sure how deep but I have pounded in some long t-posts probably 2 or 3 feet down without hitting the shale. Will the fence still shock with this shallow soil & rock underneath? Also, I have three grounding rods that are 9 foot long. I know there is no way I'm going to get anywhere close to that far down, Should I cut them in half & pound six of them in if I can only get a few feet down? BTW - Charger is a 50 mile , I believe it is 2 joules. Thanks!
