I have asked the same question of the Case IH Dealers - nobody knows. In fact, they have never seen one before. Even when I showed them the pics/sketches in the manuals, they looked out to lunch on that one.
If anyone knows I sure would be interested in the explanation. Be nice to have one too - even if it was just a conversation piece.
The cultivator I sold Ike had one. It replaced the spring loaded lift arms. The center of the arch attaches to the rock shaft arm, and each end to the cultvator gang.

That is what I originally thought, but with the pic, it clearly shows and the instructions call for the pressure rods to be used in conjunction with the arch.
Could it be to provide extra stiffening for say hard clay type soils
You have the general idea. I think it was used in some of the harder soils or where large sweeps or wider sets of teeth were used. It would make the 2 sides help support each other in side thrust.
I did have to get pressure rods to add to the cultivators that I bought from John.
I agree that the purpose of the jockey arch seemingly is to limit side to side movement of the individual rear gangs.
I agree, I think its the side move ment stablizer, With the wheel packing the soil the cultivator loosing it again it might have a tendency to slide frome one side to another. This would give pull from the cultivator on the other side and stop the slide off the trak
I want one
A 1952 cultivator brochure states: "JOCKEY ARCH FOR REAR SECTION. Gives added rigidity when more than one sweep is used on each rear tool bar, or when spring-tooth gangs are used. For Cub-144, A-144. Regular on AV-144."
I knew I had it here somewhere. By the way, in 1954, the jockey arch was a $3 option.
I was born in 1954. My Dad was making $0.98/hour plus shift and underground differential - I think he made $1.15 or something for going down 6200 feet in a gold mine -- not me -- EVER
Wish it was still available and still available for the 1954 price
Btw., what is the part number of that catalogue - I would love to find a copy....
