Vintage farm equipment identification.

Hi,
Hope I am posting this in the correct area.
I'm looking for information on some equipment. Preferably what it's named, what it done, who made it, from what time period.
If you can help I would appreciate it a lot.

1) spike tooth harrow
2) walk behind plow. Has some other mechanism on it?
3) hiller - planter. Probably not all that old.
4) another plow
5) mower
6) terracer builds terraces, used mostly out west
7) cultivator
8) manufacturers plate for the cultivator.
9) grain drill
10) another pic of the grain drill.

Ok, what do I win?
