Ratcheting Top Link

Inspector507 · Apr 17, 2003

The way that I thought it worked was........
To shorten the link, open valve and raise 3ph. Shortens link. Close valve.
To lengthen link, while raised, open valve and lower 3ph. Then close valve when lengthened to desired length.

Thats the way it was explained to me once, but I never saw it in action.

I thought it is opposite of what you said. Because the weight is behind the lower pins, when you lift it up the weight would pull the top link apart?

I have a Woods box blade and grading blade. To raise or lower the implement beyond gravity you could drive forward or back slightly. This provides the extra push/pull you need.

BTW...I have remote hydraulics and ordered thier unit for that.

You are correct.

Raise implement to lengthen toplink.

Drop implement to shorten toplink.

I just got on this thread and the concept seems good for some applications. I am specifically interested in using a hyd. top link on the box blade (if it ever shows up). Correct me if I'm all wet, but the unit should work pretty well for the box operation as described below.

If you wanted to rock the box forward to rip you would start moving and open the valve to allow the drag of the box to rotate it forward and close the link, and that would dig the scarifers in. You would be able to slowly ease into the scarifers by throttling the valve as you move forward until you get the cut desired.

To open the link, raise the box, or back up with the box down, while opening the valve in the opposite direction, thereby opening the link before you started grading.

Keep in mind that the valve can be located on the tractor so the reach should not be a problem.

Am I all wet or will this work???
