Do you know what this is?

Have you ever seen those sections in a magazine that show some old piece of farm equipment that nobody uses anymore? Well what is that blue thing in the picture attached to that tractor? No it is not a counter weight.... We did a little cultivating of some corn on corn ground with a volunteer corn problem. Also did another 60 acres in place of second ignite  herbicide application, the cultivating was cheaper by my math even with the extended time of labor needed. I told Roger the neighbors might laugh at our little 6 row cultivator, he said the are probably just jealous and wish they had one. You can scream with this thing up to 7mph in tall corn, a far cry from the old S tine machine I spent months of my life on growing up. It is also important to have a cultivating buddy, one of mine is pictured here. Pretty brave guy perched high on the buddy seat with no shoes. When it gets really bumpy he likes to have the assurance of his hand in dads.
