3PH top link... which mounting hole

[LouNY]

So no draft control, the mounting position will only effect how the implement raises.
See the last sentence in @wirlybird s post for each position.

Last two posts are interesting. @RayIN's manual says to "go lower" as load increases, and @wirlybird's says to "go higher" as load increases.

@RayIN what kind of tractor you have?

@wirlybird On your photo of the manual page, it looks like the mounting holes move forward as they move up. Is that correct? Mine all line up vertically.

Thanks for the all the responses.

My MF cat2 top casting looks like this:

It pivots at the bottom, the top is attached to a very strong spring that activates the hyd sensor.
BTW, that is not a picture of my tractor, it's a copy N paste from the web.

Yes, and for me anyways, I select the bottom one for things like my brush hog which I want the rear to raise more when I lift it, whereas, with my box blade or land plane I may want it to raise more parallel to the ground while I am using them.

I have always used the center hole on my non draft control equipped tractors. My pole barn (built last year) required me to use the bottom hole to lift implements high enough to clear the entryway ramp to the barn.
The barn was built on an existing slab that required the wonky ramp, but I should have made the entry ramp longer than the 3' concrete ramp that I poured.

Typically, with non-draft control 3pt hitches, the only reason to use the different pin location on the tractor side is to change how the implement is raised.
Top pin hole normally lifts the implement relatively parallel to the ground. As you lower the pin location, the implement is raised in an arc as well as being raised higher.
The lowest pin location will raise the implement the highest when in the fully raised position.

True. If on relatively flat/level ground it may never be an issue, but if in hills or need to cross ditches a few inches of extra lift may be the difference between continuing on your way and the rear axle being losing traction.

I only have "position control" on my Kubota L5030 ... But I have mine in the top hole of three ... Have only used it with a brush hog so far ...

My TC45DA says “Attach the link using the lower hole, 1; for light draft loads, such as mowers.

Attach the link to the top hole, 2, for heavier draft loads, such as ground engaging equipment.

 

[ksbrdmkr]

For inground the draft actually forces the the top arm towards the tractor depending on how much draft. So if there is a draft sensor in the top think leverage.
