when these older balers first came decades ago many farms didn't have a tractor with a pto as it wasn't the norm yet; hence a engine (e.g Wisconsin 16hp) to be the power for the baler...
They had PTO (I had a 1930 F-30 and a 1941 M Farmall) but the PTO was not live. When you depressed the clutch to stop the tractor motion, the PTO stopped. Live PTO was developed in early 50’s.
1960's factory built...... I have not seen anything like this in modern production. You may have to find one in an old barn somewhere. New Holland also made a similar version with flywheel running perpendicular to the JD version. They both used Wisconsin 2cyl motors....
+l337pwnage It is important to note that most motorized equipment is powered for motion/transport. Powering the PTO and attached equipment requires much less. There is a lot of unused HP in most mechanical applications. Using draft animals for motive power, in combination with small motors for direct power for PTO (etc.) is a very effective and efficient strategy..... all scale dependent mind you.... If horses are used for both motive and mechanical power, such as a ground drive implement, it becomes much more difficult.
Carl Russell : Well, from my anecdotal experience, most of the time we used full throttle on the tractor was when powering equipment, even in stationary applications. Using full throttle simply for moving, even with heavy trailers, would result in unsafe speeds quite quickly. Now that I think about it, though, we could get away with pretty small tractors on a baler, not so much on a chopper. I think in the case of a baler, the huge flywheels they normally have probably do a lot of the work. All the balers we used had massive flywheels.
