Hydro-Gear ZT 5400 Transaxle 

Greatest invention in mowers.So efficient!

Awesome. Was wondering how these things work!

Just replaced the center section in mine. These are pretty simple, but ingenious.

Excellent

I have left side hydro-gear that doesn't have full power after overheating due to fan failure. Anyone have any idea what I need to replace to fix that? Tia

J'ai tout compris

Volume doesn't work??

Those planetary gears don't do anything here

Great video so the whole thing is immersed in 20/50 weight oil and it’s sucked in and transfered from where to where ? I see how it flows so is the drive pulley spinning a swirling it around ?! Great video I need to tear an old one down I’m slow forgive me
