Oh i remember my neighbor complaining about this a while back.ZD21 how to disengage the hydrostats for moving machine with no engine running. I have looked thru the manual and find no mention of it.
I have the same question, did you find out how to disengage so you can move the mower?I've got the same issue/question on my G2160. I've owned 2 other hydro machines and both had a way to disengage but I cannot find any such way on the G2160
