Can't start this thing it is a great tractor but have been having trouble starting it with key. I turn the key to glow plug, it sets, turn to start position and nothing. Battery is up but no start. It's like the transmission is not returning to neutral position or a bad neutral safety switch. I had to dealer some months ago and it worked about a week or so and returned to same problem. I have to go 100 miles to get it back to them. Any help or idea on what to do or what is not happening so I can use my Kubota ?
