My John Deere LT155 needed new belts. I took the 38" deck off and changed that belt, I placed the LT155 on blocks got underneath the unit and changed the main drive belt. When I tried to start the tractor, the breaks no longer work and the unit will not start. I assume the tractor is not starting because the breaks are not operational. So I put the LT155 back on the blocks and removed the LS driving rear tire to see how the breaks are operating. I'm just not sure what to do next!
