Their manuals are available on line through Mathews Company website. Go to resources, then look for discontinued models. Your model is the same lower flail cutter as the Lawn Genie Models and parts are available. If you are replacing bearings, they are available through your local bearing supply store. Flail knives are available through MC, but have to be ordered through a local dealership and sent to them. I think they will ship to just about any dealer. Good luck.
