</font><font color="blue" class="small">( Don, that is an older model, I'm not sure what model number that is, but I understand it is the generation older than the model I have (it may be the early version of what I have or it may be a generation older). I emailed him several times, he does the same thing that the guy I got my unit from in that he takes apart large units and makes 2 row planters out of them. He seems to also do a quality job based on the emails we traded several months ago and his photos. I don't know if those units use the same seed plates as the Model 71 Flex or not, I never got that far into his units. After I figured out what it would cost to ship one of his units from Kansas to Indiana I figured out that I needed to look closer to home.
I picked mine for 2 reasons, one was location as he is close to me (30 miles). The main reason was that when I started searching around the net, the 71 Flex units seemed to be idiot proof and so that fits me pretty well.

The unit Don refered to appears to be a cut down JD 494 planter, typically 4 row. Would not be so handy as the wheels are so wide, and you need hyd to lift it. They were about the most popular planter of the '60s so there are tons of parts sources tho.
Your 71 units were made into the '90s, and JD now sold the rights to Yetter, who continues to make them. See
www.yetterco.com - kinda burried in there, but they are in there....
Many places make plastic seed plates, I believe Lincoln Ag is a popular place, they are on the web but I can't even spell their name right, much less remember the web site... /forums/images/graemlins/wink.gif
IHC made a series of planter units similar to the JD 71 - I have a bean planter with IHC 295 units for planting soybeans. New Idea / Agco also made a popular planter unit, I think it is in the 300 range for a model number?
The deal with these planter units is that the rear press wheel is what drives the planter plate. So they do not need any other wheel drive, metering, etc. Bolt them on a frame, and good to go.
Other planters such as that cut down JD 494 use the large carrying wheels with chains, sprockets, shafts, & more chains to drive the planter units. These really only work with the frame they came with, can't just bolt the planter unit on anything - you need all the driving mechinisms...
