This just says something about this machine. It is about 20 years old, and still going. Stuff wears out - like bearings, casters, etc., but so what? The machine is so accessible and yes, there ARE many sources for parts still available. These are like and are in the same caliber as the old Buntons that JD used (I still have one of those - a 1984 model). I would say check it put.
Thank you, Dad - for always being the dad that you were. You truly are my hero. You always were.
