I thought I would see what others do and think about yearly tractor maintenance. I very seldom put enough hours on my machines to change fluids on that schedule. So, that got me to the default of being on the yearly schedule. I tend to lean towards doing my maintenance in the fall. But, it got me to thinking that others may do it in the spring. I guess my thinking is the dirtiest time is the summer and I would like to clean and maintain the equipment in the fall giving me a refreshed machine for the winter and leading into spring. So, what say ya, Fall or Spring?
