Disc Harrow Alterations

[deere5105]

Hope to get it taken back down this week and work on it again. I thought about the Loctite and wondered if it would work as stated. I do not have a lot of experience working with it. The tabs were purchased from a local tractor dealership. The hole in the center of the tab is round so it spins around on the axle. The collar behind it doesn't seem to be locking down squarely on the axle and may be the culprit too. I picked up a new spare collar yesterday while in town. May try substituting it to see if that helps. I would question if I was doing something wrong on this axle, but it is consistent with what I have done on the other three axles that have not had any issues.

The lock tab usually has an internal tab too that engages a keyway in the axle. I think if that were mine I'd snug it up and drill and pin right through the nut, shaft and all. Better yet, get you a castle nut and just drill the axle and pin it.

Have never seen one of these done that way, but sure sounds like it would work and be easy to undo.

Wondering if anyone has tried this on a disc axle?

What about something like this. It uses the axle to hold it without spinning

Had one similiar on. You can see it in the pictures in previous post. Makes me wonder if collar is not going onto the shaft where the two square pieces would join preventing the spinning. Picked up another one to replace a spare one had. The new one looks just like the one in the link. May give it a try and try it one more time. The Castle Nut idea seemed sensible.

Was able to take down and re-tighten the axle nut. I chose to try the new collar instead of the old one. One thing I noticed was the collar didn't go far on the square part of the axle. By hand, I was able to get it far enough on to not spin freely so I believe it is on enough. I







run the nut on with the impact and tapped on blades with 4 lb hammer and kept tightening. Beat the keeper down with same hammer. Got a good bit of plowing planned for this weekend. Will be a good test. Made a paint mark to help see if it is moving. If this doesn't hold, I am seriously considering the Castle nut idea and drilling the axle.

The indicator paint is a good idea. Its too bad there is not enough thread length to allow use of two nuts locked together. My JD has that, there is no way its coming apart on its own.

Many times a new axle will also stretch a bit as everything wears in and you will need to tighten the nut many times till all the parts mesh tightly together. I think you have the right spacer on the end now so the nut should not loosen. Using a hammer to "ring" each blade as you tighten is also standard practice for tightening.

Any thoughts on effectiveness of the nylock, think thats correct terminology, lock nuts in conjunction with the lock washer?

I understand the stretching issue, but waited a while before folding the tabs over and so far have had no issues with any of the other three axles. Makes me wonder if, even though I re-cut them after they were damaged, there is a thread issue. Would question the installation if were having issues with more than just this one axle. Could have got the axles longer when/since I ordered and replaced them all, but at that the time didn't seem necessary.

deere5105,
Have you considered the possibility of shaving the outside spacer spool just enough to get an extra thread or two? If you can do this it should help with getting the square shoulder more room to lock on too. I am referring to the spacer between the last two blades on this gang.
