Selling this for my dad as he has downsized to a condo. Commercial quality lawn mower with a blade brake. This unit has an aluminum deck and 3 speeds for the self propel system. it also has a bade control system so you don't need to shut it down while you empty the bag or move something off the yard. Large rear bag and starts easily. Runs perfectly. Great mower if you have a big yard! I don't need this mower as it is too big for my small yard at a townhouse...open to offers.
