We have a new to us JD 1910 air cart and I am wondering if there are any tricks to cleaning it out. It's the first time running JD for us and the cart is very different than our old one. Generally I just blow air everywhere and pressure wash it and call it good. Do the meters need any special attention or do I just remove them, blow them out, and they should be good next spring? Is it worthwhile spraying diesel on any parts? Thanks for any tips or comments.
