The first link is to a patent for a TA in 1935 that JD chose not to market. The 2nd is for the MIV transmission which stood for mechanical infinite variable transmission. Patented in 1969 but development started in 1958. It was even installed in a few 4020s and sent out to farmers for testing. It worked but the reason JD didn't market it because there was concern of the high cost and long term reliability with all of the precision parts needed. The picture is of one their rotary combines they were working on in the late 50s and early 60s. To say JD didn't spend much on R&D is idiotic. Just because they didn't put it on the market doesn't mean they weren't working on it. You can accuse them of being conservative and not being the first in innovation but they sure weren't last either. And they did have some firsts anyway. I'm betting if you take IH out of the equation JD was spending more money in R&D on AG equipment then any 3 of the others combined.
