Posthole Digger Leinbach L7300 Post hole digger

[rickmacheske]

I just used my Leinbach L7300 for the first time today. I'm trying to figure out if I did something wrong or if it just won't fit my tractor without modifications. Basically, when I installed it the auger bit dragged on the ground. I couldn't lift it high enough. To me, it seemed like the U shaped bar that goes on the lower links is too short. Any ideas? I'm thinking of welding on about 6" of additional material on the U shaped bar.
Thanks,
Rick

The top of the "U" should have the option of connecting to one of I think 5 holes in the plate welded along the top of the boom. Which hole is the "U" attached to? I have a 7200 and use the middle hole and this gives me adequate clearance with my tractor. The closer you connect the "U" to the tractor, the higher the boom end will lift.

I tried the one closest to the tractor. I'm thinking the U is just too short. I tried to find something in the instructions but they might as well not have any from what I've seen. I'm going to try to fit it better tomorrow to see how much material I need welded on the U....

Does your tractor have another set of holes that the boom pole can fit into? Try the lower ones if available...I agree that that the instructions are pretty poor...

Also if your in the 1st hole when you raise the boom are you sure it is not binding against the U keeping the 3 point from going all the way up your tractor shouldn't have any problem with that PHD. Post a pic so we can see what is going on

I tried the lower set of holes on the tractor. On level ground the auger drags about 4 inches.

Is there any adjustment on the tractor for the height of the arms? One thing that I have always thought was odd is that the arms don't move until I move the lever to about 5. Really the only change I get is between 5 and 8.

Ok...here are some pictures.

The first one shows how high the boom is when the 3pt is raised all the way up. The second one shows the rear end of the tractor. The third one shows what happens when you use the lowest pin setting on a L3400. Basically, I need to find a way to raise the boom..... I can either mod the U or raise the 3pt lower arms on the tractor. Suggestions would be greatly appreciated.

In the third picture, it looks like there is another lower hole in the toplink bracket. Am I seeing it correctly?
Another thought, does the Pats links push the lower arm attachment point out a little? If so, removing them would straighten out the support and possibly gain some height. It may also allow moving the support rearward into another hole closer to the tractor.

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....
