Summary

I had a lawnmower with a very non-ergonomic throttle bar. The throttle bar had to be held in constantly, and with substantial pressure. Using this lawnmower always left me with tired thumbs and utter disappointment.

This clip was designed to attach to the handle from where the lawnmower was steered. This part is clipped onto that handle. Once the throttle is engaged, the smaller side of the clip flips down to hold the spring-loaded throttle bar in.

It's a small part to fix a small problem, but it did the trick.
