Weifang CP 504, AKA TY series tractors, AKA defunct TMT brand in Australia - what hydraulic fluids should I use and where?

[catmanjan]

Hello this question has been asked a million different times but a lot of them are conflicting - what is the latest advice on what fluids to use?

In particular, my tractor has two pumps, one for the steering and one for the loader etc.

Should I use an ISO 46 in the steering and a UTTF in the transmission sump?

If your transmission and hydraulic system share the same oil then use UTF, which you can also use in your power steering.
