1992 jd 855 mfwd front diferential lube ?

Hi , I have a 1992 855 mfwd and I want to change the fluid in the front diff also interested in changing hydraulic filter in rear ? and ask if anyone has the procedure and fluid amounts ??? thanks in advance ! This tractor is going to be used all winter long almost daily and want to do some standard maintenance before I leave it on the property so if you know of anything else that should be done PLEASE let me know The new Property is 60 miles away and I want to do whatever I can beforehand ! , Grumpy :thumbsup:

The owners manual doesn't specify any of the fluid info? I would also check the antifreeze freeze rating.

Sorry , I don't have a manual or service book , just trying to find someone who does ! thanks
