I'm performing the 50 hour fluid change on my tractor. The manual says change the oil, front diff, transmission/hydraulic, and read diff fluids. That's a lot of fluid (10 gallons or so).

Anyway, the manual isn't real clear on the type of fluid to use. They specify some LG specific brand that of course isn't available anywhere around here, so I would like to know specifically what type of fluid the Front and Read diff are suppose to have. I'm guessing 80w90 gear oil, but I would like to do better then guess. I'm pretty sure the Main Transimission takes standard Tractor hydraulic/transmission oil.

I'm also a little confused on the rear diff drain and fill spots. It seems there's an inner and outer rear diff. I see how to drain the outer, but not sure how you drain the inner. Any help would be appreciated!
