I bought a used 2019 Grasshopper diesel zero turn mower with 189 hours on it last summer. I had all kinds of problems with it initially including a starter that didn't always turn over. I realized after I bought it that the mower had been buried pretty deep in mud or something as the dashboard was full of mud.

I had the starter rebuilt this spring and the rebuilder said it was full of dirt. The mower had to be buried pretty deep to get dirt into the starter. I started it about ten times since the rebuild and the dang starter quit again! The volt meter was showing the voltage dropping quite a bit when turning the key so the solenoid seemed to be engaging. I rapped the starter very gently and it started right up after that. I think this mower is cursed. I am sure the shop will fix it for me, but I don't really want to be without a mower for nearly two weeks during peak mowing season.
