I am working on neighbors 2950 with cab. The hydraulic clutch stopped working so I opened the bleed on the slave cyl to see if it had air in the system. No air and no pressure. I put a new clutch master cyl on, bleed the system and still no clutch and no pressure. There is a 1/8 line from the slave cyl to the bleed on the Hi Lo trans. Opened that bleed and got plenty of hyd oil but no pressure. I am more than sure I have all the air out of the system. If the slave cyl was bad I should see some leakage but I do not see any. But I do not know where the hyd oil goes on that HI Lo system. Could I be losing pressure somewhere on the HI LO and how do I determine I do or do not. My IT shop manual says to bleed the HI LO bleeder but says no more about it. It doesn't even show anything about the HI Lo and I do not want to start ripping into things without having an idea what I am doing. Can I simply plug the line going to the Hi Lo and get the tractor working just to get the corn planted. I don't care if the HI Lo doesn't work just to finish the corn. Any info will be appreciated.

Clutch on JD 2950 is hyd operated with brake fluid BUT is no way a hydraulic clutch. Clutch disk should dry as the Mohave desert.

I forgot to ask while bleeding have you been keeping reservoir full of brake fluid. Slave cylinder is very difficult to bleed.
TX Jim: Yes the reservoir was kept full or 1/2 full. And you are correct this is a Hydraulic activated clutch and the disk is dry. I have done several web searches and
found a lot of info on the 2950 hyd clutch and the difficulties associated with bleeding it. I will probably jump right back into this sometime on Sunday and give an
update on my progress.

The line to the hi-lo is just an interlock if I remember right. I think there was a service bulletin to eliminate that anyway. Remove the line to the hi-lo and plug the fittings that it connects to on each end. It was something to do with preventing shifting of the hi-lo with the clutch disengaged.

Take a pump oil can fill it with brake fluid,and put a hose on it and bleed from the bottom up with the oin can pressureing the fluid up to the master cylinder.I trier it and it works well.
