I managed to lose my key while I was driving the tractor. It's still out there in the field, somewhere. The dealer charged me $5.50 for two new ones, and she gave me a Kubota-orange key ring to hang them from, just so I wouldn't do that again.
How did u misplace the key while driving the tractor? Can u remove the key and it will keep running? Never tried. I had an ole amc hornet that u could do that with.
