Hi I'm new to the forum and just hoping there's someone who can help me out. I have a Toro z5035 zero turn that's five or six years old. Today while I was mowing it just stopped responding to the controls. I didn't hit anything nor did I hear or feel anything when it happened, it just stopped moving in forward or reverse and on both the left and right sides. I don't even hear the motor go under a load when I try to drive it. I worked the controls in the back that allow you to push the mower but that didn't help. The motor runs great still, the blades engage and it had no trouble starting. I checked the belts and neither are broken. If anyone has any ideas I would greatly appreciate it!
