Cannot activate Harvester

[Sarge]

I just bought the Platinum edition and began the tutorials. In the first tutorial where I have to use the harvester, it wont let me activate the harvester head itself. Is there a control that i am missing. I am using the keys that it tells me to use but im not getting anything.

connect the head then turn it on

I've done that. Thats what the problem is. I connect the head but it won't turn on. From what I can see B is the key to operate the head. When I am sewing the seed on the machinery before the harvester tutorial I don't have a problem turning it on with the same key. I thought that there might be something that I'm not extending or another key to operate.

unfold the harverster with X key

That's it. I was focusing on the head not the harvester itself. Man i must have lost some brain cells at Christmas. Thanks for the help.
