716H wont move

The first thing I would look at is to make sure the two little plungers under the seat are up. They are located under a spring loaded lever that you push down to free wheel the tractor

I think I found what you're talking about they don't seem to move I took them out to clean but doesn't seem like they come apart should the buttons go down easy or are they stuck? Also have a sound coming from centrifugal clutch and have no pullys spinning

if your belt isn’t spinning it’s not the buttons. And yes they do stick if you don’t use them. Soak them in penetrating oil

bad news then. That gear box is out. And it’s expensive to rebuild. But in my opinion worth fixing the ole girl

well do you have an old small engine repair shop with experience with them. Or you working on it yourself. If you don’t have parts books, you can look up parts tree. Type in 7016 and look for simplicity and look for bevel gear box. A lot of folks on here use sandy lake implement and ask for Brenda

I just searched around for a pair of gears for you. They are not cheap.
