JD 30 bale thrower not working ??

Baled 100 bales and thrower just stopped throwing bales. Came back on after missing a few bales then stopped altogether. Trip mechanism actuates but nothing happens. Any suggestions what is causing this?

Spring broke inside the valve so it is not returning. I can not post you a picture since JD changed their parts sight. Maybe TxJim will see and post a picture.

JD, the old site is still up, if you use the direct link...

Will it trip by using the handle on the outside (left) of the ejector?

no

Here's photo of control valve JD Seller requested. My knowledge of bale ejectors is very limited as none were ever sold in my area.

IF it will not trip using the outside handle, and the spool is moving, you have no flow from the pump. Even if the relief valve is stuck, it should move a little. the relief valve is the one with the number wheel.

Need to take hose off at the valve coming from the pump and see if oil does come out. Don't dead head the hose or you will fail the pump as then there is no relief valve in the circuit.

Is the pump turning? Belts tight? Oil in reservoir? Recent filter change in the tank?

On my #42 ejector, the handle wouldn't move after the ejector got warm - even then, cold, it was very difficult to trip. I was thinking, how is it possible for a bale to push the tab at the pan.

I took the cap off where the dial goes on (hope I'm describing this correct) and cleaned/greased the 4 spring loaded pins the spool moves against. Reading the manual, it is an annual service as I recall. Anyhow, once I cleaned and greased everything, it kicks everytime.

However, I'm not out of the woods, I've got a fair amount of "hum" from the system. At first, I thought it was in the tank and now I think it is at the pump - or maybe both. The hydro fluid and filter are new, but very warm to the touch. Won't burn you, but you know it's hot when baling.

Some of the noise I think is just the belts running across the flywheel and on their backside on the idler at the pump. Whatever it is - the kicker is working great; concern is 2nd cutting and/or next year, the pump or something else goes out.

But back to the OP's question - I had success getting my ejector to reliably kick everytime by cleaning/greasing the 4 pointed/spring loaded pins that the spool pushes into when actuated.

Good luck,
Bill

Take the cap off #10 and see if parts are all rusted. Clean and replace.

OK I haven't had a chance to work on it yet but will look at all was suggested when I do. I did have the spool out of it a few years ago because it was very weak kicking. I greased it and it worked fine. I only use it for a few hundred bales a year now so that could be part of the problem. Thank you for your help.
