When you say "significant leaks" what is that exactly?
The reason I ask, I had what I thought was a significant oil leak and wanted it repaired under warranty BEFORE the warranty expired. I spoke with my dealer, and his first question was "what is significant?" To him, a leak that is flowing a stream of oil, or spraying oil, is a significant leak. A few drips every few minutes is "typical leak" is a seep, where it might drip, but more just gets things dirty under there.
I forget what the military uses to classify a leak. Its like a class 1 is a weep - just wet around the seal, class 2 is a drip, class 3 is a small stream, class 4 is a spray under pressure... or something like that, its been years. Anyway...
My tractor was leaking at the seal at the front drive shaft as it enters the transmission. It was a a class 2, a drip every few minutes. My dealer was NOT concerned about this leak and deprioritized it. My tractor sat at the dealership for a few months simply waiting to be looked at, when the mechanics got slow. Then they had to get the parts ordered, and then they fixed the leak... kind of. I can see where the paint was taken off the bolts, indicating a wrench was used, but the leak was about the same. Not sure they did the work or not. To this day, that seal leaks, a drip every few minutes while the tractor is running. Its just one of those things.
Now I could have taken the tractor back to the dealership and asked to have it actually fixed. And they would probably hold on to the tractor for a few months, order parts, "fix" the leak, and the cycle continues. It wasn't worth it at the time, and that was a few years ago now. It still leaks, and maybe when I have to replace the clutch or do other work down there, I'll replace that seal or otherwise fix the leak.... or sell the tractor for a new one. Either way, it doesn't bother me. Just have to have a drip pan under the tractor when I park it on the concrete.
So that's why I ask, what is a "significant leak," because you may not get the tractor back before the snow flies.
