1 row picker

recently purchased a model m12h ser#7630.Can anyone help?/? cannot find anything on this cotton picker,it is on a super M,gas tractor.found ops manual formod 120.it has 2 fans,mine has 1 fan.top of header is cast aliminium.

Can't help you; just enjoy having it. The MAJOR difference, iirc, between them and the JDs was that the gears (or the rear-end) could be changed so that you had 5 forward gears, whereas with the JD, what you had, was what you kept (one forward gear with the letter and number series, 2 or 3 with the new generation tractors).
Don't know the picker model, but there's an old one mounted on an "H" rusting down behind my shop. It belonged to my wife's uncle and it was vandalized about 35 years ago. After a couple of years with it sitting in the turn row, he gave it to me to get it out of the way; don't know what I thought I was gonna do with it..........

Tim,

M12H was built in Memphis. Numbers built by years: 1945, 1; 1946, 0; 1947, 175 (made in Memphis but prior to Memphis plant dedication in April 1948); 1948, 1120; 1949, 1459; 1950, 667; 1951, 2146; 1952, 1845; and 1953, there were 150 sold in addition to M120 models. There were about 152 pickers made prior to the M12H and the first serial number was 501. Early picker serial numbers were consecutive by all records I found at WHS. I have picker serial numbers in a spreadsheet. The chassis serial number under the operators platform and the row unit serial number should be the same if the row units have not been swapped. If the tractor was made for the picker it will have a CH in the serial number and tractor year will be same as picker. Some tractors were a few years old and converted to pickers by a dealer or the Memphis factory. Most M12H pickers were single fan models; some were modified to dual fans. The M12H began and ended as an aluminum housing over the row unit; earlier units had cast iron covers with limited experimentation with cast aluminum as early as 1942. The M 120 had a steel plate cover. I have a manual I can scan for you. The M 120 manual is very similar. I have several pickers and some parts if you need something. Where are you located? Email open.
