Satoh S750 3 pt stopped working

[jimnelson]

Was running a brush hog yesterday and all went well. Parked the tractor last night and lowered the brush hog to the ground. Went out this morning and the 3 point hitch wouldn't lift it. Hydraulic oil level was down only about a pint, but still no joy. Control and draft levers still operate normally. Is there an easy way to check hydraulic oil pressure on this tractor? Any help much appreciated.

Is there anything else hydraulic on the tractor beside the 3 pt hitch?

Post some photos of the pump. Any rear remotes?

Possibly you knocked the pump's suction pipe while bush hogging and now it is sucking air.,

No other hydraulic attachments. No rear remotes. Can't see any indication of loose fittings.

By some mystery, I fixed it. Don't know how, but with the tractor off and on, I went back and lifted the 3 pt by hand a few times with the draft and position controls in the down position and for some reason, it started working. Had air trapped in the system somewhere??? I'll probably never know, but I appreciate you taking the time to help.
