So I took your advice about using the FEL to drive T-posts. I remembered someone had said to do that, but couldn't remember who. I looked it up on my other thread about stuff you have to have to start farming... and it was you. That seems like forever ago. Anways, I don't have the longer tubes like you have, and as such I wound bending the first one I tried. Stupid mistake actually. After than I kind of got the knack for it:
I also didn't have a good way to judge height, so I had to use the hood:
We got about 6 inches of rain over 4 days, so the ground was relatively soft. That helped. last week would have been like driving them in concrete. I pushed a little, then let off to let the post relax and scoot under the FEL if needed. Over all, worked like a charm. Thank you VERY much for the tip there.
One of my cows decided to pay a neighbor a visit. She must have been looking for her calg because as soon as she saw it, she hopped back over the fence and hasn't been a problem. The place where I was driving these is an internal fence that just isn't quite high enough to make me feel good. I dropped about 50 posts along this existing fence row and will run a couple strands of barbed wire when I can get back out there.
I also learned a valuable lesson, horns don't conduct electricity. There's another internal fence, 3 strand high tensile electric on T-posts...

You can see in the picture there's taller grass in the fence line. The polled animals don't go near it, but mine are wanting that grass so they graze right up there. Their horns will push the wire out of the way, and they can reach it. Without even meaning too Shooter pulled the feed wire (the one supplying electricity) off the post over the gate. I wonder if they've ever been shocked because they don't seem to respect it the way the other cattle do. They could easily lift up while grazing and strip all 3 wires off the posts. I'm going to have to have something more permanent in the back and figure out a way to make the electric work with those horns. I think a higher top strand would be fine as they'd likely sniff with their nose up in the air or touch their neck while looking over and they'd get a jolt, but down low the horns seem to help them a bit.
