I have a Super Z 60/28 EFI, just tripped 50 hrs. I want to change Hydralic filter and fluid. Form your experience, what is the beat way to access the filter for removal. Looks like the filter will have to be removed from the bottom of the mower or remove battery and possibly remove from the top side. How would you raise mower high enough to get under and keep mower level to remove filter and drain fluid? Thanks for your replies.
