Combines What hydro oil for landN is the bestIJ

Dexron II or the Agco equivalent, N manual calls it AC401 but that is 20 years ago.

AGCO 411 is the current oil

dexron was all we ever used in l2 N7 . they switched to universal hyd. oil in the 97 r72 we run now. Not sure when the switch was made. I would be concerned about any oil except dexron in those combines.

They changed here because Dexron was not handling the high ambient temperatures we have during harvest. I would NOT use Dexron in my machine.

What oil do you use nowIJ

I would stay with the Dextron. There was some changing of orfices ect. when they went to hydralic oil. Hydralic oil has improved greatly over the years and I think that is the main reason Gleaner made the switch in '97. Not to say that hydralic oil is better now than Dextron but it is more common with the oils used in your other equipment. I know there are people that have switched oils without a problem but it wouldn't be me. Maybe check with the guy that did switch to see if they flushed system or changed anything else before making a switch.
