Hydraulic Oil for Zetor 5211

[Motohaid]

Just wondering if the problems with my hydraulics could be that the oil used did not meet the specs required by my tractor. Can anyone tell what the hydraulic oil specs are for a Zetor 5211? I thought I would drain and clean everything in the hydraulic system and refill with the proper oil to see if it works before going any farther. Any help would be greatly appreciated.:confused2::tractor:

This gearbox has no wet clutch or wet brakes so 80W90 Gl4/5 will be ok.

SAE 80would be gearbox oil!
The op is asking for HYDRAULIC oil, I have TDH universal tractor fluid in my ZETOR 8011 (gearbox and hydraulic, dry brakes)
