Jim....Details are pretty much what we are discussing here I believe... Since the tractor is gone now, we don't know if it was "hot wired" so-to-speak, or if they had a key, but Heavy equip. keys are all like this... one fits all. This one was under a protective shed in PLAIN view of many homes, and on a moderately travelled primary road. Whoever took it was doped up or hard up...maybe both. The reward must have far outweighed the consequences of them being caught. The empty beer bottle helped a bit too I'm sure.
I guess all the farm machinery manufacturers feel this way...The chance of having to pay for an insured piece of equipment being stolen will cost less than the tooling for automotive style ignition switches. This tractor was insured through Kubota, but the owner is still having to pay a monthly payment until 30 days has past(since it was stolen), and still has to foot the bill for a rental. I'm gonna' watch this closely as I too have the same insurance!
We all are in the same boat here. Anything that will hinder a thief could be useful. I think I'll hook a 110 to a seperate piece of metal around my switch, and plug 'er in at night...and let 'em have it! I just have to remember to flip the switch off before I crank it!
