I was travelling thru S.W. Ia today(with a camera) and came by where our 237 picker ended up so I took a couple pics. I still remember getting off the bus the day it was delivered and seeing it sitting in the yard for the first time. Looks a little sad now...
I have seen a little two wheeled cart used to deliver JD 227 and 237 pickers. I don't know if JD supplied the drawings to make it, or if each dealer who had one had copied it from another dealer.
The one I saw was at the JD dealer in Fremont, NE.
Up until a few years ago, one of my uncle's JD 237 pickers sat on the north side of Nebraska Highway 92, just west of Yutan. The same guy had purchased 3 of the 20 foot Behlen cribs that they also had.
