I currently have an old JD LT155 with bagger and high lift blades. (22 years old) I would like to purchase a new JD but was hoping to be able to mulch most of the year, but still have the option to bag for general cleanup as needed. Is this possible? Is there a JD model that I can purchase which allows me to turn mulching OFF and then allow the cuttings to exit the side into a bagger option? It would be best if I didn't have to change blades between mulching and bagging modes. Thank you in advance.
