Ariens 93603800 19Hp Kohler engine..42inch deck
Getting used to the forum,.patience please. I just acquired an Ariens 42inch cut 19hp kohler powered lawn tractor. Used but runs fine. Needed only to replace the deck belt that was broken. I want to replace the transmission fluid in the machine. Youtube has vids on replacing fluids, but did not see a machine with the exact tranny. It has a Hydro- Gear transmission 12-AABC-1x1A 1GX7 followed by 9167k20251. I did find the fill plug on the top of the transmission and was able to view the level, seems fine, but unknown how long it has been in there. Does this unit take the 20-50w fluid or is it something else. I have tried to view a service manual, no luck as yet..thanks for any help given..
