Buy a large diameter PVC pipe or conduit 90 degree elbow and wire it to your subsoiler. 5 or 6 dollars.
Your top link does that by adjusting that by shortening or lengthening the link.Has anyone fabricated extra weight for their single tyne ripper for burying pipe? I need mine to go deeper than it seems to want to. I thought about welding arms on to pick up the ballast box. 400lb of weight should help it somewhat.
That's about what I'm planning on doing. I've about a 300 foot run so I might be pushing the limit of cat6.I built one from scrap and dragged in irrigation pipe. It was cheap to do. I then pulled Cat 5 into the pipe. I would caution you on this though, I lost equipment twice from local lightning strikes. They didn't need to be real close to fry my network gear. I replaced the copper with fiber and a transceiver at each end, cost maybe $100 but no more lost equipment.

Be very careful about burying Ethernet. You can get ground loop issues between different buildings.
