Repairs Z4200 drive won't engage

[tlw]

I was mowing with my Z4200 mower yesterday and while using it the drive quit working. I checked the belts all look fine and no leaks anywhere. Mower runs but won't go anywhere any suggestions? All cables appear to be fine is there a relay that could of went out? levers are hard to move when mower s running like there no pressure.

Recheck the drive belt it goes from motor to the hydros. It probably needs replaced.
