i am trying to change hydraulic fluid and filter on a 9020 simplicity and cannot find a drain plug..looked under the rear axel housing...it has a rear pto and can i loosen other hose fittings to get as much of the old stuff out,,,poor thing is needin love...

Need to remove bottom frame cover plate exposing hydro unit. Then on forward bottom of rear differential casting there should be temp sensor that you remove. It doubles as drain plug. Some times the temp sensor has been replaced with standard plug.

Good luck Mike

well it was tough to get the sensor off after king kong tightened it last.....had to put a breaker bar on it...it dont have to be that tight i hope.....the rear cylinder still leaks down but no were near as fast....i think it may be a bad seal unless you have any other ideas....and thanks again for the help...

make SURE you bleed the hydro per the manual.
