Bought the aerator (Landpride CA1548) last January and I also added the casters to the flat metal discs.I just have a thing for keeping everything clean and waxed.I did the tractor this weekend and probably spent 10 to 15 hours cleaning and waxing it,wheels ,engine and even under side of it then there was the MMM also.I know to some people its just a tractor:confused3: but its easier for me to keep it looking new and shiny.:cool2::drink::cool2:
