HST stoped working

[Nuebaden]

TC35D HST . When you let off pedal would keep going. Have to bump other pedal to stop. Forward or reverse. Then it wouldn’t stop at all unless you force it out of gear. Now want move at all. What to do?

Sounds like a bolt or pin fell out of the HST linkage tied to the HST shaft.

Check pivot points for debris build up,maybe good spray cleaner than spray lube or grease.
