1850 fluids

[550Doug]

My 1850 manual says to use SAE 10W or ATF type A in the hydraulics and the over/under. My other tractors just use hyd oil 32 or 55 weight just fine. Will this work also on the 1850?

It's OK in the hydraulics. I'd use Mercon ATF in the Over Under.

I don't know if you think you will have JD, IH, or CASEIH tractors down the road but I would give thought to using either JD's or CASEIH hydraulic-transmission fluid in the 1850 hydraulic system as those tractors are negatively sensitive to any other oils. This way implements could be shared w/o affecting tractors.

I knew the guy at the case ih store and he would bring to me. Made it so easy I just changed everything hydraulic to it. No problems. Kubota's,
Oliver's, Caterpillars and of course the case combine and such get it. ATF in the over/ under.

Doug, I used universal hydraulic oil in my 1800. Never had a problem. As the 2 speed hydraulic shift slipped
a little in low side I changed it to type F transmission fluid. It has a different additive in it that causes
the clutches to grab better. Stopped the slipping.
