I don't work in the department that sells the tractors, so I am not an expert in them at all. I will say that we had a Christmas sale on the tractors and the prices posted were very close to our best employee price (5% above our cost). I don't have the ad in my hand right now, so I can't quote any prices.
Also, if you buy a tractor in one Cabela's store, you can get it repaired at any other Cabela's store(that has a shop/sells them). I am not sure about if they can be fixed at any other shops. I just texted a person in that department to get an answer. If they are available and answer, I will post it up soon.
