Back to the Junior with the mounted cultivator pulling the swather. It did look odd but back in he late 50's and into the 60's, I remember Dad and Grandpa pulling the rear cultivator gangs off the tractor so they could pull something or use the PTO. If they needed to do other fieldwork such as roteryhoeing, making hay or even pulling the combine for oats they would also remove the front gangs leaving the main frame on the tractor.
They had hydraulic lift two row cultivators mounted on the 30, 33 and 44. There were just four front gangs. The lift rods were held on with a spring pin and the gangs were held onto the beam with a breakover latch. It only took about 10 or 15 minutes to put the cultivator on or take it off. So in June or July it wasn't uncommon to see a tractor with all or part of a cultivator mounted on it pulling another implement.
