G'day MM
I don't specifically know who repairs them but when I did a search I got the following.
Hydraulic rebuild specialists in Australia that typically service Eaton hydro units:
Hydraulic Services Australia – operates nationwide, handle Eaton/Char-Lynn/Toro hydro rebuilds.
K-Tech Hydraulics – rebuild hydro pumps/motors for turf and industrial machinery.
Toro-authorized service centers – some of them do full Eaton hydro rebuilds or can ship out to Eaton specialists.
Rex Hydraulics / Hydroline Hydraulics – Sydney/Melbourne, handle hydrostatic transmissions including Eaton models.
Tip: When calling, mention:
Eaton 6/7 series hydrostatic transmission
Metal flakes in the oil
Toro 724Z zero-turn
Ask if they do “full tear-down and rebuild” rather than just replacing seals—metal flakes indicate internal component wear, not just a seal issue.
Cheers
