This is a cultivator. It's purpose is to cut out weeds. There are a wide variety of blades, shovels, and points that can be attached in all kinds of ways. No two will be exactly alike. On the right you can see two yellow wheels. These are important for keeping the implement strait so that it only cuts out weeds. There are two points behind the wheels that make sure that the wheels don't pack down the dirt too much.
If you refer back to the top picture, you can see that there are two rows of blades that come after the wheels. As you can see here, they run quite close to the little corn plants. Their blades curve away from the crops and are intended to cut any weeds. After that comes a row of points that cut the weeds in the bottom of the corrugates and bringing up the rear is a row of shovels that clean out the corrugates to make sure the water runs down them without any blockages.
On the very front of the tractor is a corrugator bar so that when the driver reaches the end of the field, he can clean out the corrugates on the ends without having to turn around. This helps save time, which is good.
The entire machine (as well as the driver) has to be properly aligned otherwise you'll either miss weeds, or worse, cut out some crops! It's somewhat slow work, but it's a heck of a lot faster than weeding with a hoe.
