Posthole Digger Leinbach L7300 Post hole digger

Have you tried moving the pin that connects the toplink to the boom farther out toward the end of the boom/PHD head? Then adjust the toplink to be as short as it'll go... Your toplink may be binding, or you need a shorter toplink.

Have you tried taking the auger out, disconnecting the toplink and PTO shaft, and lifting it with just the lower lift arms. Thought it'll try to rotate the head backwards you should be able to shove it back up enough to check to see how high the lower lift arms will lift it... That'll tell you if the problem is in the way the toplink is connected.

Just a thought... thank goodness I don't have to hassle with a 3PH any more... Though, I am thinking of getting a Leinbach and putting a QA plate and hydraulic motor on it.

Here's a picture with the toplink in the lowest hole. Because Pat's lifts the lower arms up, I would think that it helps if anything....

Think of a triangle. You have lengthened the bottom of the triangle with the Pat's adaptors, thus lowering the other 2 legs of the triangle. Try it without the Pat's and see how that works.

I figured it out, sort of... It's definitely the adjustment on the height of the arms on the 3pt. I removed the stop and found that I have a lot more movement past 8 (the furthest point). I did some checking and found out that I have no movement until after I push the lever to about 3.5. Here is what it looks like when I remove the stop. Does anyone know how to adjust the 3pt for height that it lifts? For now, I'm just removing the stop.
Thanks,
Rick

I'm not much on geometry, but if it was me, I think I'd try using one of the adjustment holes closer to the gearbox. If you do that your u-frame should stay more vertical and give you more lift. Had the same problem on a used no name phd I bought, but it was going the other way. Once I had it vertical it was a foot or more off the ground. Losing the quick change ends would help to.
