I am not sure how a dealership is supposed to know who wants to be pestered and who wants to be left alone, and many times, there are people like me, who would prefer to not be pestered until I ask for help. I would judge their eagerness to help you after you actually go to the desk, counter, or reception area, and _ask_ for a salesman to help you. Lots of people standing around in dealerships are not shopping for anything - they are just there waiting for the parts guy to fetch their order, or just dropped off their machine in the service department, or are standing around waiting for their buddy to finish his business with the dealer, etc. If you ask for assistance and none is forthcoming, then you can judge them to be rude. In general, my experience is that a tractor dealership is going to be a bit less of a high pressure environment. I wouldn't exactly expect eager, young, salespeople running out the door in the rain to kick the tires with everybody they see get out of their truck on the far side of the lot.
As far as when the salesman was already with a customer, well it was just plain rude for him to go off and help somebody else. Unless they have a set appointment, Miss Manners would say that each customer deserves the courtesy of being assisted in the order they arrived. Of course, they should always be courteous enough to let them know how long the expected wait will be with a "Somebody will be with you in a minute", or "I will be with you next," or even "I am afraid we are swamped today, there are three other people waiting already - please help yourself to some coffee and the brochures on the rack if you care to wait..."
As far as making sure the dealership will do what they promise after the sale, the best advice is "GET IT IN WRITING" After that, "GET IT SIGNED". Make sure everything on your side of the deal is included in the paperwork and not left to "oh thats our standard policy", or "of course thats included, we just don't write it down here" If there is any resistance to your request that something be added in writing, well then maybe they didn't intend it to be part of the deal.
You may find some resistance to put it in the paperwork if the salesman is "unofficially" promising you something his boss would never approve. Its basically an offer to make you an accomplice in stealing the promised item. If you feel OK with that, thats your decision. If he gets caught in the attempt, or doesn't follow through, you might not have any recourse.
For example, when we purchased my Wife's Ford, I asked for an extra (3rd) set of keys including the remote because I know they are expensive if lost, but probably have a pretty low actual cost, so I negotiated those into the deal. Sure enough, when the truck was delivered, no extra (3rd) set of keys and the explanation from the guy in the prep department was, "They come with two, not three". The original saleman was not working that day. Referencing the paperwork with "Extra (3rd) set of keys and remote" listed on it solved the dispute in seconds with no hard feelings either way. Without that paperwork, the scenario would have been a bit different: If they don't give me the keys, I think they are cheating me, and if they cave in, they think I might be trying to cheat them...
Salespeople may have great intentions, but if something is disputed that may have serious financial consequences, then they really don't have the authority to make that promise. Nor are they the one who has to back it up. Salespeople leave dealerships all the time. Also, believe it or not, customers lie about such verbal promises all the time, so it always is an awkward situation when you are not dealing with the original promiser. I'd expect the salesman to follow through on the things under his personal control - like when he will call you back, but not on some significant monetary promise like "free service for life". Get those kind of promises in writing if they really intend to follow through on it - its part of the deal. If they are offended by you asking for it in writing, then maybe they didn't really mean what they promised, now, did they?
