MF285 Open or Closed Center?

IFF · May 29, 2016

I am getting conflicting information on whether my 1976 Massey Ferguson 285 has open or closed center hydraulics. Does anyone know what it is? Thanks.

The auxiliary hydraulics are an open center system on your tractor.

Thank you Dieseltech. By the way, you answered a question about the priming of my 285 after changing fuel filters. You nailed it on the head with that one, some knucklehead put an o'ring on top of the filter and choked off the fuel flow.

I've lost count of how many service calls I've made with the NAPA-WIX fuel filter top inlet groove plugged with an O ring. Never a problem with the CAV filters.

I made that same direction in a Facebook group to a guy that was having the same issuesa month or 2 back, and boy did I get scolded by some of the know it all's.... then a short while later another one of them suggested the same thing but worded it differently, and was met with open minds...
