I am building a set of forks for a 3 point hitch and am going to make it a true category 2 implement. Photos will show the brackets I have to create a flange that the lift arms will be received by and will be pinned through to complete the lift arm connections.
I've perused diagrams showing dimensions for Cat2 on the web, but what I am wondering, with this type of arrangement, where I should center the lift arms so what I build works universally on a cat 2 hitch. Diagrams seem to lead me to believe 32 1/2" is the center to center from each lift arm, but does that cover what it needs to reach to each side of a lift pin on an implement, you know what you need to swing past the pin, then back onto the pin ? You need extra space to do that when lined up to an implement to get the arms connected. Is there a typical, outside of lift pin to lift pin dimension for category 2 ? I then suppose once connected and you push the arms onto the pin to abut the inside of the arms against the base of the lift pins on the implement, that would work universally and could be used to center a flange connection like I am building.
I see Speeco has a quick hitch, and it receives the lift arms the same way, in a flange that a pin runs through. The center of that flange is what I am after, and I thought of contacting them for that dimension, but thought it a good one to post here just the same. It seems I could use one of these quick hitches, would hate to build my implement and not have it fit one of those.
I just want to make sure once I build the top link mast that will bolt to the flange connection as shown mocked up in the photos, I do not make it specific and only fit to this tractor, or be off enough to not work. I realize these are standard for 50 years or so now.
I can adjust the brackets each way.
I also have just picked up an McConnell Manufacturing Co. Inc. 7' 3 pt Cat 2 rear blade for snow removal, cheap way out to make use of this tractor for snow. Its a really heavy well built blade, and vintage, early 70's though I can find nothing about it on the web, was made in Prattsburg, Steuben County NY. I am wondering if I should just mirror the dimensions on that implement, at the lift pins and center my lift arms where the abut the base of the lift pin. I already have the 24" center to center of lift pin to top link pin established.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
