Sc60tx problem ( won’t move forward or backwards)

[treedebris.jv]

Hello everyone, I am new to this page and am already coming here with a problem in hopes to get some feedback. I have a 2008 sc60tx stump grinder and it recently stopped moving forward or backwards. The machine starts up just fine and there’s no problem there but as soon as it’s on for a few seconds it will flash a the wheel cutting light and stop moving forwards or backwards. Thankfully I got it on the trailer when it did this now it’s now coming down on its own and I’m down a machine.

Any feedback appreciated
