Oil & Fuel Deutz Fahr Agro Plus 67 (2013) hydraulics

[Erle]

Tractor has 1130 hours. Hydraulics work great for about an hour. After they get hot they will not lift(3 point or hydraulic ports) Have purchased all new filters, although I would expect this to be more of a pump issue than a filter problem. Need to know what kind of hydraulic fluid to replace with as I can't find Akros Multi fluid. Also pump location, testing / verification and possibly where to find a service manual for the tractor. Finding info for this tractor online is almost impossible. Only other problem with tractor is the M6 alarm.

Build yourself a hydraulic system pressure gauge and test the live pressure in as many places as you can, both hot and cold.

Make a thoughtful table of the recorded values and see where the information takes you.

It may be a priority valve malfunctioning. Or a Pressure regulator not behaving properly. "filters or the exact type of fluid? I doubt it!

Thanks for your reply. I ordered a test gauge this morning. Should have it Friday or Monday.
