I have a 2015 Gravely Pro Turn 160 with the 60" deck, 500 hrs. It was just in the shop for a few weeks because it would shake really bad. Come to find out it was the PTO Clutch. I mowed with it yesterday, and it runs and cuts fine, just when I was done and brought back to idle, it still has the same shake it seems like. The drive belt, one side is just shaking back and forth. Also the mower deck seems to have excessive play from side to side. Has anyone else experienced the deck having a lot of play? There are two arms that come off the back of the deck and mount to the frame. I'm wondering if these are worn out or some type of bearing gone bad?
Normally deck shake boils down to bad belt, pulleys, spindles or blades. Think about what might not be running straight and true when changing speeds, causing a wobble.
