Old Farm Equipment I have Seen

My wife and I recently went to see an exhibit, Becoming Van Gogh, at the Denver Art Museum. On the way to Denver we drove past many old abandoned farms and I took photos of old farm equipment that I could see from our car speeding along at 65 mph. 

We drove past coyotes,

past many windmills,

 

and past abandoned farm equipment.

 

 

The photo of a piece of equipment shown above appears to consist of an old hay rake and another part with large straight spikes. The latter part would appear to stab or pierce the hard earth as it was pulled across a field. Now I wish I could go back and look for the manufacturers name.
