I plan to change the fluid in my machine, since I don't know if it has ever been done. My service manual says to use Melroe hyd/ hyd transmission fluid no. 6563328, and if not available use 10-30 or 10-40 (SE or SF) motor oil. Is the Melroe fluid your regular universal tractor fluid that comes in gallon, 2-gallon, or 5-gallon cans, or something altogether different? The stuff I use in my Ford tractors has a long list of different manufacturers specifications it meets, but Melroe isn't listed. On a related note, I don't look forward to purchasing a transfer pump to suck the fluid from the reservoir. Can I just thread a Tee fitting into the outlet hose, and drain it? It sounds so simple I wonder why it wasn't designed that way.
