My riding lawnmower (tractor) has 5 gears forward position and one gear for reverse. When I was mowing the lawn today and went over some rough grass and weeds, the tractor stopped and wouldn't move. I moved the gear to every gear but the tractor wouldn't move. With the help of my son, I pushed the tractor back into the garage. I did notice that, even though the tractor was in gear, I was able to push it. Before today, when the tractor was in gear, it could not be pushed. There isn't much room to look under the tractor, so it is hard to see what's not working. From what I can see before taking the tractor apart (which is BIG job), there is some sort of belt that depressing the clutch pushes against. Any idea would be appreciate it.

After looking at under the tractor for a bit and playing with the clutch, I found the problem. The drive belt came off the drive pulley. This drive pulley is located in the rear of the tractor. There is a metal door in the back covering the pulley, and a metal rod next to the pulley to keep the belt from slipping off. I opened both to be able to relocate the belt on the drive pulley.

Honda Harmony 2013 will not go in reverse what is the problem?
