My Murray Riding Tractor will not go forward or reverse when in gear. The engine is running but when you go through the gears it just runs through them with no movement forward or reverse. I replace the belts and still nothing.
You didn't say what model you have but if it has a push mode lever it could be jamed or just not working. if it is an older model that has a varable speed transmission take the floor panel off and see if the varable speed pully is not moving.
