Hydraulic fluid choice?

(quoted from post at 11:05:06 11/16/12) Forum members,
I have chosen a 10 weight hydraulic fluid for use in my 8N Ford. I know this seems light but in the cold temps of Minnesota it works a lot faster than heavier weights. My question is, is this weight hydraulic fluid a good fit for the gear components of the tractor? The tractor does not get extremely hard use nor prolonged use-snowplowing and hauling wood with a FEL. Any thoughts are appreciated.

• [*:32f07264c4]Regardless of viscosity whatever you use it should be a combination type oil designed for common sump use in a manual transmission, drive axle, and hydraulic system. Do not use a conventional hydraulic oil.[*:32f07264c4]My recommendation for general all season use is a good Universal Tractor Transmission Fluid. There are a number of different brands and they are all similar with only minor differences. Most claim to be suitable for use in applications specifying M2C-134D (and a host of other OEM specifications). [*:32f07264c4]The viscosity of most UTTF type oils is somewhere bettween 9 and 11 cSt @ 100C and they typically have a viscosity index in the 130-140 range makiing them excelllent cold weather performers. For those that insist on speaking in SAE gear and motor oil grades I'll leave looking up the the equivalency to them.[/list:32f07264c4]

Forum Members,
The label says, AW 32 Hydraulic Fluid. It is farm rated. Fleet Farm said it is equivalent to a 10 weight oil. Like I said, the tractor does not get extreme use. Any other thoughts are welcome!
