Toplink top link

[dvan1966]

Just courious on where the top link connects to the tractor there are 3 holes.
What is the reason for having 3 holes and which one to use?

They are for attachments of different weights. I think the top one is for light weight, middle for medium weight, and bottom for heavy weight. I could have that backwards though, I dont have my owners manual with me. It works with the draft control.

Here is what my manual lists for a kubota 3130...

My JD 3320 has three holes. The manual says:

ｷ For light and medium draft loads: Install center link in bottom hole of mounting bracket. Example of light and medium draft load implements would include a landscape rake.

ｷ For medium and heavy draft loads: Install center link in middle hole of mounting bracket. Example of medium and heavy draft load implements would include a tiller or box blade.

ｷ For very heavy draft loads: Install center link in top hole of mounting bracket. Example of very heavy draft load implements would include a plow or ripper.

That explanation needs qualification, it's only relative to the use of draft control (if so equipped). And the B6200 is an 80s vintage sub-compact, too old to find full specs on. As such, I seriously doubt it's got draft control

Otherwise it's a matter of matching the geometry of the toplink with the lower lift arms - when the attached implement at it's operating height. The idea is to pick the holes that align the toplink as closely parallel as possible with the lower lift arms.

Thanks for the info. My manual dosen't say anything about it. I don't have draft control and the only thing 3pt implement I have is a RB. I was just courious if there was any reason to move it.

...the only thing 3pt implement I have is a RB. I was just courious if there was any reason to move it.

Not too much stress imposed by a rear blade, so in this case it probably doesn't make much difference. The main thing to take away from this, is that aligning the toplink as closely parallel as possible to the lower lift arms will produce a working geometry that transfers the most horsepower to the job.

You might also find that your RB will lift higher (depending on your individual set-up)when the top link is in the upper hole as the upper and lower links are no longer parallel. This can be a big help when trying to get it up out of the snow, just like shortening your top link.
