Camera needs to be on a tripod.  Or at least braced against something.  Use delayed shutter or a remote release if possible.

Disable Auto focus and manual focus if that option is available.
Open the lens as much as you dare.  Depending on the field of view all the way if possible.
Take a shot.  If digital you can Chimp it and then adjust the exposure.  I do not know what type of camera you are using but if it has full Manual now would be a good time to learn the exposure triangle and use manual exposure.  Take several shots at different exposures.  Shoot in Raw mode if possible and adjust the exposure in photo shop.   Or the software that came with your camera.
The shots with the stars in the background was a long exposure.  Probably over 30 seconds or many shots stacked.  Very little lighting would be required for the tractor.  The moon in back of the camera or a flash light could be used for lighting.  Or you can do multiple exposures on one frame either in the camera or with Photoshop.

Did say a tripod and remote shutter release is a good Idea. :-}
You can get good results with almost any equipment if you experiment a little.
