I don’t enjoy switching implements either. Some tractors (like an 8N) have a fixed lower arm, which means you have to have things perfectly lined up to push the lower arm on the pin of the implement. At some point tractor makers figured out that they could make the lower arms “extendable” so you didn’t have to line things up perfectly to get the lower arms hooked up. You just have to be within about 3" of the implement pins, with the extendable lower arms.
They make a crow’s foot extension for older tractors. I’ve not used one of the bolt on types in the vid below, but I used to have a couple old Oliver tractors and they used a crows foot hookup out of the factory. I liked that system a lot and could hook up the lower arms without getting off the tractor.
One thing I don’t like about the crow’s foot hookup in the “Pat’s Easy Change” vid is that there is not way to move the lower arms back and forth from the tractor seat. Pat’s Easy Change looks like they use some adjustable bar to set the lower arm spacing, but the problem I see is that if your different implements have different width spacing between the pins where the lower lift arm engages (likely) then you have to adjust that bar spacing each time you switch implements, on Pat’s system.
The system Oliver used had small ropes fastened on each crow’s foot which would engage the spring loaded clasp from the tractor seat. You could also use those ropes to pull the lower arm horizontally from the tractor seat, which made hookups pretty easy.
The vid shows a guy installing Pat’s system on a tractor which already has the extendable lower arms which seems pretty pointless to me, unless you have just one implement to attach and remove. But I can see an advantage of Pat’s system if the tractor doesn’t have extendable arms and one can put index marks on the different bar spacing of the lower arms, for each implement. Or perhaps one could drill index holes in the bar for the different implement pin spacing.
