I would like to tell you a little story about an old friend of mine. This takes place back in 1953, He had a farmall H and an unstyled john deere B. He bought a model AC 60 combine to harvest his wheat and oats. It was PTO driven. The wheat harvest went fine but when he got to the oats later on they were down. Without a motor on the combine he had to stop, shift into neutral, let out the clutch and clear the machine, push in the clutch, shift into gear again, let out the clutch and be on your way until the next plug happened or had to slow down to shaft into a lower gear. He went to see about an aux-engine for the combine. With cost of the engine and the labor for the change over it would be about 800 dollars. The john deere 50s and 60s had come out the fall before with independent PTO. He asked the dealer what a 50 would cost and he told him about $2000. So he bought the 50 instead. If IH would have had IPTO on the newer Hs he very well went for the newer H. I asked him if he thought about trading in the old B and he said it didn't owe him a dime and besides he liked to cultivate with it and it was cheap on fuel. he just left the cultivator on it so he didn't have to lift it on or off every year. I'll add more to the story later. thank you for listening to part of my life. john
