When I bought my FT 80(now 675) the drive train had 3 year warrenty. This does not include the clutch. And I think that's the norm on most tractor brands today.
Now if you are in question about the Farmtrac warrenty, I wouldn't worry. I can tell you first hand they bend over backwards if something goes wrong. example: My loader after 2 years started leaking on one of the lift cylinders. Called my dealer to get a new cylinder shipped in. When checking for the part number I found I had miss matched cylinders only by part number. They were the same length and dia. Just had a different rod end cap. Got the cylinder info to the dealer. He said he'd get one moving fast. Called me the next day to come by and pick up the cylinder. Got there and there was two brand new cylinders in two boxes and they were a match. My dealer told me to take them both and bring back the cylinders off my loader. I said how much? $$$. He said no charge. Farmtrac would make the mix up right at no charge. I was grinning.
Now the dealer may make a difference. I have a great dealer. I can also tell you Farmtrac is no fly by night co. too. They aim to to make their mark and sell a good product and stand behind it too. They are here to stay.
I think the mix up on my cylinders happened because they had just started up the new plant in Tarboro when I ordered my tractor. They were rushed up trying to fill orders and get the new plant up and running.
If I needed another tractor, I'd buy another Farmtrac in a heart beat.
