Apologies, as Im sure its out there, and I have spent time looking but have had difficulty. My experience on working on tractors is limited.

Having trouble understanding all fluids and recommended modern types to use.

Also not sure What is meant by transmission oil vs rear-end oil vs PTO pan oil

I think I got engine oil.lol

I believe hydraulic oil is simply used for hydraulics and power steering and type is basically a UTF type deal.

Confusion on rear end vs transmission vs differential

I am led to believe the oil for hydraul portion of trans is separate from the rest of transmission.

Is there more then one point of fill for transmission fluid .

Thats the basics of what I dont understand. Thanks all!
 


The hydraul (three speed over/under) is mounted right behind the engine. Takes ATF.

Rear end/transmission/differential/PTO? is all semantics. It's the same thing. 80-90w gear oil. You PTO uses this reservoir for lubrication. The filler is on the floor board by the gear shift lever.

The hydraulic unit sits under the seat above the rear end. The dipstick/fill is right there in front of the seat. Universal hydraulic fluid will work.

Now if you get fancy you can use Mobil 424 or the like in everything but the engine. But I don't have those kind of dollars.
 
Thx scootergmc! That helps. I might have been
confused as well as i was YouTubing it and referencing a
1600 in a video and it must have a little different layout
than 1655 in regards to fill points.
