I found it on tractor house when browsing one day. I was looking for a four row 30 inch spacing planter for doing plots (can legally drive down the road with it on a trailer with just a standard overwidth permit) with and came across it at what I think was a heck of a price. I am riggin it up with the no till coulters and trash whippers and liquid fertilizer. It has the dry fertilizer on it already. It is a 1990 model 6100 and is in excellent shape. Extremely rare no doubt and mouch easier to service/clean out than the maximerge planter boxes.
