Ive got a kubota l345DT 4x4 that will go into low range perfectly and work all day. The second I put it into high range it’ll move about an inch then stop. Tractor has around 800ish hours on it. I’m new to the site and kubotas. Help would be muchly appreciated. High range did work till I fired it up today to take to my house and all of a sudden high pretty much stopped working.
