Hustler Super Z LS Hydro stopped working suddenly

[mowing4me]

I was out mowing today and as I was making a pass I suddenly notice I no longer have any forward or reverse on Left Side Drive. I see no signs of burst lines, Fluid reservoir is full. Drive belt must be intact or else RS would not work. From what I have looked up it could be the wheel motor or the Hydro-Gear pump. Any Hydraulic specialists out there that can give me a what to check first list. Once I can get it back in the driveway I will jack it up and test if there is anything flowing that will allow the wheel to turn under no load.

Thanks in advance

Hydro pumps and pump motors don’t suddenly go bad. So check hub as stated for starters.

Thank you for the tips! I will check that out. When I was looking for new motors I noticed they had a shear key type connection. That will be much more cost effective than a new pump or motor.
