    Default JD 4200 HST wont go forward or reverse

    Hey guys, my JD 4200 HST stopped moving yesterday afternoon. It was driving fine while box blading and just stalled out. The blade didn't have anything in it at the time and the engine RPMs remained the same. It would not move forward or backward. I engaged the PTO and it would move a little. I changed that Hydro filter and it would move a little but then would stop. I did notice some metal shavings in the old filter. Oh and there was plenty of hydro fluid in the machine. Any ideas? I'm afraid this is going to be expensive to fix, if it can be fixed, or am I going to have to replace the entire transmission? Any advise, information, and/or prayers would be greatly appreciated!

    Did you clean the Hydro screen?

    Not yet. I had a friend of mine come help me move it yesterday evening and he suggested that, but after looking at the filter he is afraid it is to far gone. He is a heavy equipment mechanic and will look at it when he gets a chance, but it was raining when he got there, so he used the crane on his service truck to get it loaded back on the trailer.

    Thanks for the fast response, KennyD and I'll make sure we do that first and see what that does.

    A complete failure of any hydrostatic tranny is pretty rare unless it is totally abused and/or the wrong fluid is put in it.

    How may hours are on it?

    USMC.27 will the machine move if you select another range using the range shifter?

    I have a 4210 and a few times I have shifted from range to range and had my hydro shift lever hang up on neutral although that position wasn't indicated. May sound stupid but how does your 4200 engage 4wd (assumes you have that feature) I am wondering if your 4wd switch may have hung up somehow. 530 hours in nothing on a hydro transmission if it has been decently maintained and not run low on fluid.

    Another possible cause of loss of drive is failure of the torsional damper in the flywheel. I have seen a lot more of these fail than the hydro. A certain amount of metal filings in filter is normal. Did hydraulics still work OK? Try to see if the shaft between the engine and transmission is turning when you try to move.

    He has a 4200 so it is mechanical, not electrical like the e-Hydro on the 4x10 series.
