    650J blade will not lift

    Has anyone ever seen a solenoid that looks like this? The far left one is the blade lift and I’m not as familiar with John Deere but I think that might be an aftermarket solenoid. I’ve tested everything, including the rigged wiring and I’m failing the solenoid.

    650J no fuse box cover, can't find TCU or ECU pin out anywhere

    Hey yall, TCU is losing can communication with the infamous 91.9 ecu and 609.9 sdu codes. Dont have the serial number for this dozer, it's got a 4.5L power tech in it. I have access to the fuse panel, but it doesn't have a cover on it to show what fuse goes to what. Can anyone send me a fuse...

    Johne Deere 650J Fuel Rail Pressure

    I just replaced the high pressure fuel pump on a 650J. I was wondering what the normal operating fuel rail pressure is supposed to be? I’m getting a reading of 7540 psi at full throttle. Thanks Joe

    650J stutter above idle.

    I bought a 650J a year ago, ran it 5 hours noticed a fuel return fitting leaking, parked it and the next day crank no start. Long story short RDO did a ecm (not the issue) I pinned the motor, made sure I could pin the pump, sent it in in for a rebuild, put new injectors in, new filters and it...

    650J XLT Blade problem

    Hi. I just bought a 2006 650J early model. Ran it in the parking lot where I bought it until it hot warm and no issues. Today I had it in the dirt for the first time. The blade cycle times are so slow it's frustrating. With a blade full of topsoil you can barely function the blade. The tractor...
