Have a 2004 60 series sts, when we engage the feederhouse in reverse to unblock a front it engages then a few seconds later very roughly 'drops' out of reverse and in to forward?? its quite cruel hearing the noise and watching the jolt as it happens, any one had this or know what im looking for to fix it? the 60s are electric to engage them instead of the older style lever below your feet so any ideas??
thanks in advance

First are you holding the header engage switch in reverser for a while or just holding it until it starts to reverser then letting to. Also check the tone wheel on the right hand side of the backshaft and make sure it hasn't come loose. If it has you can try to retighten it but most likley it will come loose or you can go to your local dealer and get the new updated tone wheel. The new one clamps onto the shaft and holds very good. I haven't had any come loose since Deere came out with them. The last thing is to make sure that you combine has had the reverser drain fix as fail PIP done to it. Look under the feeder house at teh back of the reverser and there should be TWO hoses comming out of the rear plate. If there is only one then the PIP needs to be done. The PIP was to help relieve the back pressure in the piston when oil seeped past it. When this happened the reverser wouldn't shift fully or trip out as you are describing.

that is a weird design under there. we replaced that little piston twice on both our 9560 and our 9660.

"thor1ststech" is 100% correct in what to check, sounds like dragoguy would do well to see that the pip has been done to his machines as well. Replacing the piston only fixes it for the moment until the leaked oil builds up again. Just draining this oil off will do the same with out replacing it.

WIll Deere ever have a reverser that holds up. This has been a issue since the XX20 series.

As a matter of fact since Deere has come out with the Heave Duty and the Super High Capacity both with oil coolers we have only had to go into TWO of them and we have about 100 combines out with the two reversers on them. When we inspect the machines weather they have run over 100 acres or 10,000 acres we change the reverser oil and flush out the cooler every season. The only reason the two went out is because the input shaft seal started to leak and then eventually went out. In the hills we run around here in Northeast Nebraska when that side of the machine was down hill it was pumping oil out the seal. We ALWAYS use the heavy duty synthetic reverser oil in them all. Even down to the 20 series.
We do however have some issues with the lower sheaves but that has to do alot with maintenance. We suggest that they grease the sheaves TWICE a day with either the synthetic grease or the SD Polyurea grease and make sure they speed them up and slow them down to distribute the grease.

check the inside of the reversre for fillings it maybe time to rebuild

i agree, we have very few problems with reversers, especially the new high torque units.
you can grease the sheaves 10 times a day, but if you don't work the sheaves through the speed range, it does no good

thanks guys. i'll be sure to have them do that as it is goin in for an inspection this next week
