I had the drive coupler between the engine and the transmission break in my f935 mower and I replaced it. I drove the mower for less than 3 minutes and all the hydraulics quit, steering ,lift and drive. The transmission never made any abnormal noise , the drive shaft is turning unimpeded , nothing works. Any ideas ? By the way I was driving on level ground and the mower was not under any strain.
I don't believe in coincidences is there something I may have done installing the rubber u-joint? It seemed pretty straight forward to me.

Any help would be greatly appreciated

Tim,

You may need to start believing in coincidences.....

The coupler is a pretty fool proof replacement, How long has it been since you changed the hydro fluid and filter ?
