John Deere 9R 640 Tractor pulling an Unverferth Zone Builder | Ripping the Fields

In this video I am out in a harvested soybean field in Northwest Ohio with a John Deere 9R 640 tractor on LSW Tires pulling a 12 shank Unverferth Zone Builder. The are ripping the field around 1214 inches deep fracturing the hard pan below.

This farm was also running one of their Case IH 620 Quad Track tractors down the road pulling another 12 shank ripper and I'll have that in a future video.
