Bob,Shawn, post a picture of it. I don't have any of those tractors and can't offer solutions (sometimes poor ones) without knowing more about the situation.
For the overall length you’ll be creating, I think a 3/8 rod would serve you better. Thread the top end and put on a knob to make it easier to grip.
Was the week to mow with it again. What I'm thinking about doing is putting a lever on the front right corder of the battery box. Gave some thought and a big tall lever might just bounce out of engagement like was mentioned. Still going to give it a thought, but front right corner seems handy and would be kind of out of the way.Funny you should mention that darn lever....I am going to do the same thing. Awkward and a real reach. I was just going to thread the current rod, but on one of those connecting collars and attach a 18" (or so) rod that is bent 60 degrees to the right for about 6" and vertical again. That's the plan. Although a one piece rod would probably be better. Let me know how it goes!
