If I might summarize the conventional wisdom of the pros here:
1) it's hydro fluid (not motor oil) so apparently not a big problem with a little old stuff mixing with new stuff (unlike motor oil)
2) dump the entire rear-end and filter, have a beverage of your choice while you wait
for it to drain
3) clean out the rear end of any "goo" you see AND clean all gasket mating surfaces (rear-end and filter...I use plain old rubbing alcohol)
4) replace the rear-end cover with a new gasket (question for the pros here...dealer told me the silicone "form a gasket" was fine for the rear-plate).
5) replace the filter (with a light film of hydro on the gasket). Just a hint...popping that valley cover pan between the seat and steering wheel makes things easier for old guys like me)
6) get your wallet out and go find a Cub Dealer to buy 8 qts (question for the pros here...we live in JD Green land here...I assume Cub Cadet and IH used the same hydro and also assume JD uses the same...right or not???) Roland says you can buy bulk if you take clean containers.
7) get a funnel with an attached tube, open up the drain plug on the rear cover (I think it's a 3/8" square that works with a standard SAE socket extension). Start filling until you get a hair shy of over-fill (finger test).
8) clean and replace the plug, fire it up and run it through the motions a little bit. Pull the plug out again and top up if you lost any fluid in the process. Replace the plug.
9) Pros here say to simply change the filter periodically from there...you need about a qt of fluid when you do that.
ok pros!!! how'd I do for amatuer explaining the process???
