3 point connections

Nyquil Junkie · May 25, 2023

I'm rigging up a counterweight on the 3 point and it suddenly occurred to me that I'm not real sure how to properly do it.

First up is this top link connector, it has 3 holes. Before I break something, which hole is for what? I'm hooking up a counterweight that is going to be set and chained up at a good height. So which hole should a hook the toplink to?

Speaking of chains... I assumed those 2 hooks on the side of the rearend were to hook the limiter chains to and the other end of the chains hooking to the end of the lift arms at the pins. I actually have no idea id that is correct or what those hooks are suppose to be used for.

Help me out here w some info and maybe some pics how you guys do it.

Thanks.

Hooks were bolted there by some previous user and would be fine for chains. I use the lowest top link hole because any pulling force to top link, then places less stress on the draft linkage.

The three position top link was for different draft implements. Heavy draft, like a 2 bottom plow,
would be connected to the lowest hole; medium draft, maybe a disc, would be connected to the middle
hole; light draft, like a cultivator, would be connected to the top hole.

My understanding was the top most hole wasn't
used for draft work.
More like for use with a sickle mower.
Not for hauling around a heavy counter weight
either.
I'm forgetting my N history tho...
Was the 3 hole rocker optional?
And maybe didn't come out till the 8Ns?

Did not come out until the 8N with position control And the hooks were to keep the 3 point hitch from droping when engine not running. Use the bottom hole to lower the load on it to keep from breaking.

Heavy work like plowing and discing are done with implement set to bottom hole position. Lighter work such as cultivating can use top hole position. What exactly are you
planning a counterweight for? Got a FEL? The 3-Hole Rocker was changed in 1949 at s/n 215759 and the Long Pin 8N-486-A, was obsolete in 1950 at s/n 237336 as part of
the main issue for the infamous Ferguson/Ford Lawsuit. The shorter 8N-486-B was now effective. The rear end diffy case was also changed too for the ears to use the
shorter pin. Note in your top photo the furthest bottom hole. This is where the 486 Pin goes but yours doesn't look right. It should be solid, not hollow like a bushing.
In 1955 Rocker was changed to a 2-Hole Unit. Denny Carpenter makes both the Long Pin and the newer shorter pin. The hooks are not Ford parts; they never had them.
Somebody probably had check chains added for limiter chains BUT, with the 8N came POSITION CONTROL and thus no need to use limiter chains.

t has to be a hollow tub for the long pin to go thru ears and rocker.

Position control only worked if engine running. Would not help with engine not running as tractor setting for some time and oil leaking past cylinder letting load drop, probably why hooks added. But may have had implement mounted with pto shaft that would not let lift be operated without disconnection pto shaft.

Do you have a loader? What are you counterweighting on an N?
