IZT motor, oil capacity question

This is my first post. I have a 2003 Hustler FasTrak 44" mower. The IZT drive motors are slipping badly when they get hot (183*F by heat gun); to the point of complete loss of drive power. Today I suctioned out 63 oz. of oil from each motor. It was dark brown, with a somewhat milky tint, which may mean there was some moisture in the motors. I have never serviced the motors because my owners manual states "no maintenance is required".
Now I need to know what oil to put back in the motors. My dealers says 30W motor oil. The Hustler online owners manual says to use 20W50 motor oil. Also the online manual talks about changing the oil filters on each motor, but I cannot locate any "filter".
I need advice from the experts, please.

I know it's not about the IZT hydros, but I think the EZT hydros are similar. If you Google 'ezt zt2200' you should find the PDF service guide for the EZT hydros. Hope that helps.

I've read that guys use a synthetic oil as a replacement in the EZT hydros and it is supposed to prolong the life of them.

Yes, it is 20W50. The lawnsite guy emailed me early today. He said my 2002 IZT hydros do not have a filter screen. I refilled them today and the hydros seem much crisper and more responsive. Now I have to readjust all the linkages, they somehow have gotten out. Thanks everyone for your advice, my questions are satisfied!
