Well just drained the hydraulic fluid out of my new to me 9N, and it's easy to see why they require it changed every 600 hours
It get dirty

Your oil is typical of water contaminated oil.
Water may come from condensation and the engine isn't used in winter to get rid of condensation.

Just my guess. May be wrong.
 
My first tractor purchase was a 9n. I went to change the transmission fluid and had to dig the slop out by hand. It would not drain.
 
Do an experiment. Let the oil sit for a while.
See if the water settles to the bottom.
Post it back.

When I drain the gear lube from my 4x4 kaw mule, it looks dirty. I left it in an oil bottle for a long time. All the dirty stuff settles to the bottom and the oil on top looks like new. I use that oil in my chain saw.

My terramite uses 10 gallons 10w40 in hydraulics and I should change it every 200-300 hours.

I save that oil in old oil bottles. After a while the oil clears up. I use the oil in my old lawn mowers.
 
just how does the air get in the tranny and cause water to form mine set in the shed so i dont have that problem even out side it would take a lot of air being forced thru the tranny to get condensation and how does the air get in the tranny where is the opening
 
The water condenses on the sides of the case, the runs down the sides. Over a few years with little use it will accumulate a fair amount of water. And each time it is used and not enough to get warm enough to evaporate it out it mixes with the oil, till it is like an emulsion. Then will not settle out for a long time. Other ways are loose fitting levers and lck of being stored inside and then if subject to heating and cooling with changes in humidity will still build up moisture in the cases.
 
My Jubilee got water in the tranny because the shiftier boot was bad.
I don't leave my tractor outside. I don't wash my tractor.
 
Way, way back oil and fuel dealers would service farm tractors at the farm. They would drain the differential and transmission oil and then pour kerosene in as a flush. Drive the tractor around a little bit, shift, back up, etc. and then drain the kerosene. Then they would put in the recommended oil. I think that might help clean up your situation.
 
I was considering putting in a mixture of kerosene and oil to wash that junk out, maybe a half and half mix. Mite try that before I pull the pump.
 
could be water leaking in round the shifter too. or other plates and covers that aren't sealed well after time.
