John Deere bale thrower.

I have a Deere 346 small square baler with I believe a #30 ejector. last summer the pan would trip, but stay up in the air. What I did was clean and grease the detent cap held on by 2 allen screws, behind the number disc for bale throw distance that didn't do anything, I pulled the entire valve assembly off, brought home took it apart, cleaned it, looked for anything broken ect, changed the hydrulic oil in the tank on the thrower. I do have the manual for the thrower, although it is not very helpful. Put is back on, still does the exact same thing. I called Deere to see about replacing the detent cap, its $700.00, thats not a problem, but. I hate to buy it and find out that's not what's wrong with the valve. Any ideas or problem anyone may have had like this, thanks.
 
I have no knowledge of JD bale ejectors as very few were used where I live. If you have a model 30 ejector I suggest to get a JD TM 1311. BUT JD parts shows ""model 346 baler has a model 42 ejector"" which lists several different operators manuals & a different Tech manual # 1584(2nd photo below)

My friend was having problems with his. After a few different episodes and trying different things he told me that it took completely dismantling and cleaning the valve.

Yes that is the manual I have TM1584, I was wrong, its not a 30 ejector.
 
My thrower pans stay up if they trip at an idle so I assume it’s related to the pressure when tripped. You say you changed out the fluid but did you clean the screen filter in the tank? Also, the 2 small springs under the latch break occasionally. Check them. I believe the arms won’t latch correctly and act as you described too.

One other thought, check the spring in the base of the thrower cylinder. If that spring is broken, pan does not return to the set position either. I’m not sure where you are but my balers sit outside. However I have sheets of rubber roofing on them to keep rain out of the control valve. They will corrode

Im in upstate NY, I was JayinNY on here in the past, but svcummins and I got blocked, but im back on. My baler is stored in side. If you mean the two little springs to keep the latch cylinder locked until it throws, they are not broke.

I will change the filter, as i did not do that last summer.

I also forget to mention, my thrower has the yellow side screens, and the sides do not flip up.

The spring inside the throwing cylinder is probably broken unless the spool in valve is not returning home and pressure is keeping pan from returning home.
42 ejector is newer model with biggest difference is the screens.

This is interesting, as it reminds me it was 50 years ago I worked on one of these! The only thing I remember is the bushing which the valve actuating arm pivoted on started to set up. I believe it was on a 3/8 inch carriage bolt. I had hand tripped it and it worked OK. But once in the field it didn't work. All I did was loosen the bolt temporarily, and it worked until I could fix it correctly. I doubt this is your problem, but it wouldn't hurt to check it.

I replaced that spring 5 years ago, but thats worth looking, into the old one was in pieces, thank you.

Hi Jay, good to see you posting! SV was posting now and then under a different handle, I don't recall what it was. I haven't seen a post from him in maybe six months though. How is the diner doing?

Check the springs near the tiny latch cylinder, it has to be fully down and latched to cycle properly.

Hi, the diner is doing good. I text SV, he is still staying busy, I went to Macfaddens winter auction, not the same as they once were. Hope everything is going good for you!

Cannot operate properly when tripping at idle. Needs pto speed.
 
When the pan is in the air....after you reset the safety, does it not reset?
I do not remember. I know when i shut off the pto it drops back in place, but Id like to know what your saying, what could be the problem. Thank You.
 
Ours would do that periodically. We simply reset it with the safety or lockout (pan can't kick) and it reset and would work just fine.

The pan is returned home by the spring my b inside the cylinder. It has to be at pto speed when tripped so the pan is thrown with enough force to compress the spring to return the pan to latch home.
