Good point. And thanks for the response. I want the diesel fuel locking cap because I am having some of my nephews help me grade the lane, plant trees, etc. I do NOT want the to add gas to diesel. I almost did this with my fathers J.D. Yes, he got a little excited there. Secondly, i never thought of an Anti-theft mechanism. Does Kubota make them? Is there an after market for that. I will be keeping my 'bota in the garage so I shouldn't have to worry too much......thanks for your replies....
