Z330R Quit Moving

[Kenbu]

First mowing of season 2 with this machine. 22 hours on the clock. Starts right up and running along fine for about 15 minutes on even ground and suddenly it stops moving. The levers move normally, but no response from the hydros. No change in engine rpm.

What would cause this kind of failure?

Thanks.

Hydro drive belt came off or broke,

That's it! A little stick jumped up there and threw the belt off the left hydro pulley. Nice diagram on Weingartz showing the belt path. Found a Youtube video on how to back off the tensioner to slacken the belt and get it back on the pulley.

Thanks!
