Transmission differential hydraulic fluid type

[cleat]

My Dongfeng 254 uses a common reservoir for the transmission, differential and hydraulics. I keep the tractor in a slightly warmed garage (kept just slightly above freezing). Hydraulics function noticably slower when first started and moved outside than in summer. However as I use the tractor outside in cold conditions to clear snow, the hydraulics get even slower as the fluid cools even more. Everything works fine, just slow. I bought universal TDH fluid from walmart last year and that is likely my problem.

What I would like to know is, has anyone used a high quality TDH fluid and what were your experiences

I can get two different shell fluids at my local TSC store. Spirax S4 TXM and Spirax S4 CX. Would either of these help ?

Would adding some ATF help ?

Any suggestions would be appreciated.

AWE32 Hydraulic oil should be fine for cold weather, I live in Quebec and we got -40F not long ago, it was alright on my Jinma.

what is the AWE of the oil you are using?

My Dongfeng uses a universal transmission, hydraulic differential fluid in a common 25l reservoir and the walmart stuff I put in has no rating. It only says it is compatible with a wide range of manufacturers. If I had a separate hydraulic oil reservoir linke your Jinma it would make my decision on oil easier.

Pardon me for butting in, but what is AWE?

Cleat, don't use any ATF. Yes, it's basically 10w oil but it contains friction modifiers that are used in friction drives.

Spirax S4 TXM is a 10w-30 multigrade UTF, and Spirax S4 CX is a straight 10 weight UTF.

I would go with the Spirax S4 CX 10w oil.

Hi cleat,

I have the df 354 with common sump. I have used Walmart utf without any winter issues. I only have slow hydraulics at the very start. As soon as the engine comes up to a steady idle all is smooth.

Mine is smooth, just noticably slower.

Likely nothing to worry about, I was just thinking out loud.
