[AT] history of PTO's on tractors .... when LIVE PTO

[Spencer Yost]

I always wanted a Roto Baler. I don’t have a single sane, logical reason other than I just love to watch them in action. Since I have small acreage I thought it would be interesting to try to use one.  Unfortunately they were never popular around here so I would have to haul one in from afar and they are difficult to transport. So I’ve never had the opportunity to buy one that was in good enough shape to be worth the effort to transport.

Plus it would take up a lot of my nonexistent shed space.  (-:  I could not keep it out of the rain without erecting a shed.   The lumber would cost more than the rotobaler (-:

The 'new' A (pressed steel frame instead of cast iron) *might* have had live PTO; I just don't recall. The 620 and everything later that we had, all definitely had live PTO. We used the 620 and 730s to power our AC roto baler.  The IH 300 would have had enough power, but lacked the live PTO, so it got relegated to rake duty. My dad said this of the original AC roto baler design: "I never baled with it without something breaking during the day. But I also never failed to finish baling what we had raked and ready." Admittedly, ours was old, and had been extensively rebuilt. Even at that, the latch plates that held the upper and lower belt gangs in the 'roll a bale" position had some wear, and would occasionally release without being tripped - either while we were running twine, or even before that. I always thought of it as the baler "throwing up" on us.

Lots of manual operation (stopping to feed twine manually, then tripping the release to eject the bale every time. I heard some tales that there was a later version, never produced or built only in small quantities, that had a way to 'hold' hay while the twine feed was running, so the operator didn't have to stop for each bale. I can only imagine the mechanical complexity of such a beast. Can anybody confirm or deny?
