Starting safety switches

[Burl hand]

I have a massey, 231, I believe that tractor to have 2 safety switches that control its starting. Where can I find them On the tractor and part numbers for each would be a joy.

Does the clutch have to be engaged?...do you have to be in the seat?...does it have to be in neutral?
Does the PTO need to be in neutral?...

Either near the range lever or transmission lever on the transmission housing - it will probably screw into the transmission housing and have a couple wires coming out of it.
