Daniel, when you take the time to look into that wompy jawed hydro on the 430, please do a thread on it. My 430 did the same thing, and my other 430 did too. Im thinking it was in the worn out linkages. They both have been sold, and I didnt keep them long to have time to look into that, but I am curious to see what you find.
I checked it out today. Here's a link to the thread about it: http://gardentractor...-speed-changes/
