There is a spring on the throttle shift lever of this mower. The mower is a hydrostatic drive and there appears to be a broken spring wrapped around the throttle lever but I cannot figure out if it is broken, where it goes or find it on the parts diagram.

On this diagram, it could part 82 or 55 or it could be somewhere else...not sure. It looks more like 82 but I cannot tell for sure since the quality of the image is so poor. Also, there does not seem to be any information about how this spring would slip onto the throttle lever and then connect to the chassis to keep the lever to return to its home position.

Any help would be greatly appreciated in identifying the part, how to put it on, etc. The mower is 14 years old and still going strong. I can probably get by without this spring if it is too much of a hassle but i like to keep things in proper working order.

 

I'm trying to figure out what you're talking about, but I have no idea what you mean by "throttle shift lever". The term "throttle lever" is normally considered part of the throttle control cable on the dash or on top of the carburetor. To further complicate matters, neither are in the pic you linked. #82 and 55 are vastly different in appearance and position. 82 holds the transmission gear shifter against the shift quadrant to keep it from flopping and #55 goes to the clutch pedal to keep tension on the transmission belt. If your spring has come off the throttle, that will be at the engine. There is a tiny spring at the top of the throttle shaft that closes the throttle when pressure from the throttle linkage is released, and there is a long spring that goes over the throttle linkage to hold the slack out of the linkage connections.

If you are talking about a problem with the shifter, what problem are you having? Did this spring fall off the mower or something? There is no spring that makes the shifter return to "home position".

Please clarify.
