I have owned a 411B for 30 years. I truly love this older tractor and it has been very good to me. I have a re-curring problem that I finally figured I would post about. The "case-o-matic" kinda stops working correctly for me. Maybe someone on this thread can help me out. Every time the transmission stops working correctly it is almost impossible to get it in gear. even lowering the rpm's to minimum still almost impossible to get in gear or even shift quickly to another gear. I sometimes have to shut off the tractor, put it in gear and then start up. The strange fix that I found to correct this problem is as follows: I disconnect the hydraulic line in the front left corner of the forward compartment. I think its the oil line that goes into the btm of the radiator oil cooling section. I inject 120 psi compressed air into this line and quickly release the pressure. once pressure is released and oil flys out everywhere, I re-connect the line and the darn transmission works perfectly for maybe an hr or 2. When my case-o-matic pressure gage did work, the gage read normal, but when the tranny acted up it read zero. Once I did the pressure injection into that line, the gage would read normal. What is causing the system to loose pressure, then regain its operating pressure after I pressurize the lines? Any thoughts?
