Help! John Deere 750 3Point Hitch Wont Raise

[beenthere]

Time to get a pressure gauge and get some pressure output from your pump.
I don't read where you said if the FEL works normal, or not.

Also, if taking the 750 to the dealer is not an option, getting the service tech manual seems to be another next step.

Does it have a front end loader? Are you sure you have hydraulic pressure?
