G1800S Hydrastat Pedal Linkage adjustment?

[philav8r]

The hydrostat control pedal has lost control of changing speeds or direction. Its as if the linkage has become disconnected, but its not because there is a wee bit of on/off control in the reverses direction.

I am able to drive the tractor in the forward direction with the speed control on the right hand side rear fender.

Any suggestions where to look for a solution? Is there an adjustment somewhere?

Found the problem. There is a pin through the pedal shaft which fixes the shaft to a lever arm which activates the linkage. For some reason the pin had worked its way out. Couldn't see the problem until I removed the mower deck and crawled underneath to have a closer look.

Ordered a new pin from Kubota.
