Putting 60 weight oil in Hydro-Gear EZT-2200 transaxle on Husqvarna Z248F mower.
The left hydrostatic transaxle on my Husqvarna Z248F mower has gotten weak and slips bad after it is warmed up. (It runs ok until I've been mowing around 20 minutes or more) Artificial intelligence has suggested I drain the transaxle and put 20W-60 oil in it. Do y'all think this would help or am I likely to do more damage? The exact model number for the transaxle is a Hydro-Gear ZC-DUBB-3D8C-2WPX. The mower is 11 years old and probably has about 700 hours of run time on it.
