What`s this switch for?

[Dman2]

Hi
There is a switch on our JD3800, which seems to do nothing
The black one in the middle
Anyone know what it is?

Takes it out of drive when you press the brake?

As said, it should disengage drive when the brakes are pressed.
You may find though you have to press the brake quite hard before it disengages drive, I have a feeling it works on brake pressure not the brake light switch.
Our 3200 you need the pedal virtually to the floor before it disengages, it’s on my list of things to try and adjust

Thats the 'RTFM' switch

It’s the ejector seat button...press it three times 2 seconds apart and it’ll fire you out
