Leaks and issues like that are one reason I prefer to buy new-warranty. Seems like if there is to be an issue, it will be in the first year or so. Went out to the shop yesterday and spotted a small puddle of hdro fluid under the 3520. Well, as anyone who has had to trace a very small leak knows, fluids migrate back and forth as they drip down over the various parts and the breeze from the radiator fan tends to send them in odd places. Think I finally found it coming from where the rubber manifold attaches to the top of the power steering pump. Cleaned the area, moved the band clamp around a bit, and tried to get it to do it while I was watching. Nope, it's one of those things that only happen when your back is turned. Guess I'll take the tractor out and work it in the cold to see if it'll repeat. As it is I hate to call the dealer and say I HAD a leak, fix it.
