Bobcat 310 will not stay still. Control levers do not stay in neutral, either wants to go forward or reverse. Instructions for adjustment are confusing and I haven't figured out. Cant begin to adjust if I don't even know where neutral is. Have searched everywhere on internet etc but can't find video or pics of adjustment (just service manual that I have). Any help someone would be able to give would be much appreciated. As a last resort, I was thinking attaching a spring to each handle to have it come back to neutral? when released.
