John Deere 410
I started her up, drove over to my fuel tank, started filling the tank, the engine seemed to bog down and then smoothed out and ran back a idle just fine. I finished the fueling, got back in the seat and none of the hydraulics have worked since. I checked the hydraulic pump at the front of the machine and it was fine (I happen to have a new spare that I installed). I checked the filters and topped off the reservoir, everything seemed OK but nothing works but the engine and electrical. I know there is a primary pump for low pressure hydraulics located behind the reverser , but I don't know how to even test it. Any suggestions would be truly appreciated. Jerry

Sounds like the pump flow got blocked then by-passed perhaps? There are test ports I remember reading one. Have you looked at the connector that drives the main pump off the crankshaft to determine if it is turning?
