It sounds like you have both oars in the water and your tiller is set in the right direction. Keep on doing what you are doing. In my humble opinion, you can never get enough education and you will be learning new stuff for the rest of your life. Only you can determine what type of training will give you the biggest bang for your buck. You said you already have good mechanical skills which should get you through most farm related repairs. How important is engine and tranny work on your farmIJ In 30 years of farming I havent run into the first major engine job and the tranny jobs, I did have required special tools that I couldnt afford to buy for the limited use I had for them. So for me, additional mechanical training wouldnt have helped much. Here are a couple of suggestions I would give my son if he were in your shoes: As you may know already, marketing is becoming increasingly important to todays farmer and having a full understanding of how markets work is almost a necessity. If you havent already gotten into marketing, you might consider a course or two in this field. You mentioned Ag Econ. Does that program include things like the rule of 72sIJ If not, I would suggest you get some advanced economics training that will enable you to make long range decisions that are every bit as important and maybe even more important than saving money on repairs. Here is another thought on major engine_tranny work. You dont have to do all of it yourself; you can hire a professional to get you started or review what you have done. I do this all the time on stuff that is over my head and the total cost over the years hasnt put me in the poor house yet. Good luck to you.
