Another Synthetic Oil Question

[DWCox]

Does this same reasoning apply to synthetic hydraulic fluid as well? I am getting ready to swap out the hydraulic fluid and recently even bought five gallons of the JD hydraulic fluid (and filter) for which the JD is spec'd. I have noticed that if it is below freezing, my power steering is jerky and makes a bit of a noise until the fluid warms up considerably--which can take a while (this is after I have let the tractor engine warm up for five minutes or so at idle). This does not happen in warmer outside temps.

In other words, could I eliminate this factor as well by buying synthetic hydraulic fluid (four gallons at more than double the cost)?

Thanks.

Either Amsoil synthetic hydro fluid or JD Low Viscosity Hygard should help a good bit with that. I believe from the factory, most of the tractors come filled with regular Hygard, which is like having 15w-40 in an engine, unless they are sent to a specifically colder climate.

Thanks. I picked up the JD Low Viscosity and I think I will go with it.

Thanks again.

Amsoil makes hydraulic transmission fluid for tractors. It isn't much more than regular fluid at the dealer but ain't cheap. Be carefull though, they sell several different kinds of transmission fluid.

I used the Amsoil hydraulic fluid in my JD 2320 - But later on I read somewhere (but couldnt verify it) that the JD Low Viscosity was also a synthetic.. We havent had enough cold weather here in VA for me to see if the transmission fluid make a difference or not..

Can any one verify or deny that the JD low viscosity is a synthetic??

one of the advantages of any synthetic fluid is that the flow is much better than a dino oil at low temperatures.. Right now I have switched over my truck differentials to Amsoil and will soo switch over the transmission...

The tractor is now running Rotella 5w40 synthetic in the engine, but amsoil in the transmission and front axle.. I just bought a case of Amsoil 15w40 for the next tractor oil change and that case will last me the next 4 years probably..

>>I had 15 w40 in mine and it hardly turned over<<

That's interesting, as I've used Amsoil 15/40 Diesel-Marine synthetic in my Kubota L2250 for over 20 yrs. now, and it's never failed to turn over and/or start.

I used Amsoil 15w-40 HDD&M for years and went to there Series 3000..way smoother engine.

Sw3 it's nice to know it is smoother. I put it in mine and it starts easlily. Yesterday it was -12 and started just a little bit slow. Last year I had 15w40 dino and then came a -5 cold snap and it hardly started.

Hey Mr. Cox, my JD 5105 did the same thing, so I removed the sump filter and it was completely clogged! I sprayed it out with high pressure hose, then hit it with low heat hair dryer till bone dry, then replaced it...and POOF - like new!
