I don't blame you for wanting to vent your frustration. That's one of the things this forum is great for. When we feel we have been "burned" we can come hear and gripe about it and have some sympathetic listeners.
I bought a brand new Honda motorcycle on a Saturday afternoon. Went by my Mother in Law's house to show it to my wife who was over there visiting. When I tried to leave it wouldn't start, dead battery. Got out the jumper cables and charged the battery a while and finally made it home. I was feeling pretty upset by then. The dealership had already closed so it would have been Monday before I could have taken it in and I had to be a work Monday.
I decided to try to at least take a shot at diagnosis myself. Alternator was not charging but following a wire I found where the wire from the alternator was not connected. Plugged it in, alternator started charging, problem solved.
I tell the story for a couple of reasons:
1. I feel your pain because I have been there/done that.
2. It might be worth a shot at trying to tighten the fitting (if you haven't done so already) and if that doesn't work disconnect it and see if you can see what the problem is. It might be something you can fix yourself in 10 or 15 minutes.
If it is a bad flare job on a line fitting maybe you could take the line to them , have them re-flare it or give you a replacement line, and reinstall it yourself.
When I got my new
B7510 it developed a small hydraulic leak on one of the loader lines, I just tightened it a bit and it stopped. By the way, since then I have been clearing woods and have pulled on the hydraulic lines with branches and developed 2 or 3 leaks where the line twisted and came loose just enough to leak. I figure that is what the toolbox under the seat is for, to carry a crescent wrench, pliers, screwdriver, and rag. When I spot a leak I just jump off and tighten it and continue on my merry way. Hydraulic leaks are a way of life with tractors.
I suspect that the absence of the tractor for a week and a half is more frustrating than the leak itself. Doiing it yourself will eliminate that frustration.
Good luck with it and don't "throw the baby out with the bathwater".
