Oil & Fuel YM 180D transmission fluid

I think that's a little pessimistic, in this case where he has an all-gear transmission.

UTF (Universal Tractor Fluid) from any of the major oil companies, or from NAPA, anybody with a first class reputation, should be adequate for a gear transmission.
NAPA was in the class action lawsuit with their hydraulic fluid damaging machines. I wouldn't go there.

There are only 3 possible fluids to put in your YM180(D).

Hygard = JDM J20C
Yanmar TF500A = JDM J20C
Kubota UDT original = JDM J20C

Ashland-Valvoline makes JDM J20C

Only buy brands that STATE, MEETS J20C and never never never 'compatible' nor 'recommended'.

I guess there are several thousand of us that are in serious trouble that have been using other brands of J20C for the last 25yrs without problems.

This is what I have compiled in my notes for my Yanmar YM2500, and this is what I’ll stay with.
