Robert, I don't recall an LA, but our John Deere L did not have a PTO or hydraulics at all. You raised and lowered a single bottom plow with a strictly mechanical linkage. Of course I've mentioned before on here about that being the first tractor I ever used. And since they were a little earlier than the Cubs, I doubt that the specs were very similar. I've found one place on the Internet that lists the L as a drawbar HP of about 7 and a "belt" hp of about 9, and made from 1937 to 1946, but we had no belt on ours; don't even know where you'd attach one. I do recall my Dad joking about the horsepower because we got it used about 1952, it was supposedly a 1940 model, and he said it was supposed to be 11 hp, but was worn enough that he figured it was about one mule power. /forums/images/graemlins/wink.gif However, he did later have the engine overhauled and it did a lot of work on our place. Two cylinder gas, 3-speed forward, one reverse, hand crank in the front end.
