Unable to reverse machines!?

[Plantman2000]

Hi all, I guess this is something I am missing but I cannot for the life of me work out how to reverse any machine (tractor/combine etc).

This must be possible.

I have tried keypad and keyboard but there isn't a clear reverse mapping key/button and even trying the Stop&Go Braking makes no difference.
The Reverse direction mapping does not do anything.

How can you get a machine to go backwards please?
Are there gears?

Cheers!

Well looks like a bug in the game with mapping keys. As soon as I map the brake key to any other key you are unable to brake/reverse a vehicle.
Walking if fine with an alternative mapping.

I have had to leave the default keys to WSAD, which is ok but not my preference, just to get the option to be able to reverse.

Certainly a bug where as soon as you map that Brake key from 'S' you cannot map it to any other key.

It is more than likely a keybind error, you will likely find the key you are trying to use is tied to another control in a vehicle that does not exist on foot
