I consider it one of my better ideas to own only a single tractor, which I use to intermittently feed hay in the winter ... hay bought from someone else and delivered to my place.
I do not have the capital expense of owning equipment. I don't have the time hassle of actually baling, much less the cost of fixing equipment. I don't need to buy / build extra barns to store the equipment in. I can bankrupt someone elses' soil ... or ... if they fertilize, I don't have to buy fertilizer. Etc. Whatever market rate is for hay sure seems cheap to me whenever I think about all of the nonsense I don't have to put up with.
Sure makes my time with my critters that much more enjoyable since I don't have to fiddle with depreciating and breaking equipment.
