The farm is on a TT system. The cable from the cut-out runs for 30m underground, then up a pole to 7 spans of aerial bundled conductor (ABC), then underground for 60m before running up another pole and along 3 spans of copper overhead.
The feed is teed off to the local transformer along the route somewhere too.
You are also correct about the newer single phase meter being for the domestic dwelling. They didn't have a trip switch in there either......
