See if you can get that video to your dealer. That's not right.
I agree. Getting the dealer aware before considering taking it there is needed.
1. While your tractor isn't the way it is suposed to be . . it also doesn't appear to be a failure in the lines . . It appears to be a failure in a couple of connections. That "likely" makes it an easy fix (again . . I said . . . "likely").
2. Optimism. Don't let your history with car dealers taint the situation or attitude. If you contact the dealer today . . remember its Christmas for him too and this is the FIRST he is hearing about it. Howver long you've had the problem . . he's hearing about it today. They will likely be shorthanded . . hectic . . Big holiday and weekend and family committments too.
3. Before you call . . Any idea how much it has leaked since you 1st discovered it? Dealer will want to know "how many days, how much leaking, did anything happen to start the leaking" ? Knowing answers to those 3 things plus the video will tell the dealer likely time and items needed to repair and how it should or could be handled.
4. Its likely they are making deliveries regularly and aybe some might be at least in your direction. So they "might" be able to schedule a stop at your location during those deliveries to either fix it at your place or take it with them. But their schedule maybe based on a 10 day cycle too. Or maybe someone might be going in your general direction for other reasons ( family gathering or major repair or supply pickup etc.)
5. In another career area I've seen this all too often in my business. A call comes in . . a problem has existed for two or three weeks but they didn't call till just today and they want it fixed today or tommorrow or really soon. Those are the calls that drive a dealer crazy because they have made committments to others that called many days ago when vacations haven't started.
6. You may still need to haul it to them . . but using steps 1 thru 5 "may" eliminate that need.
Assuming this is a very small leak . . its probably a fast and minor repair and then adding a little hydraulic fluid. So the issues are about when someone can be available to work on it with everything else going on . . and where it can be worked on.
My action would have been to notice the problem . . plug and unplug a couple times to see if that fixed it . . then observe for 24 hours. If still leaking and knowing holidays and end of year are coming up - I'd call dealer to get their input right away and see what kind of plan can be setup to fix it. The dealer is your friend until proven different.
