Walk Behind Lawn Mowers

I decided to replace my 23 year old craftsman mower and treat myself.bought a 550fh after a lot of debating.after five uses on a 60x80 back yard. I have to say love the mower easy start great cut,great drive system,BUT THE CATCH BAG SUCKS .!!!! After you get past the pull rope in the way of removing and reinstalling the bag,after five weeks of mowing bag dragging on the ground.looked for better supported bag no luck.is a better bag offered???i don't think this mower will last me 23 years or better put I will not keep this mower with this probable constant problem.poor design thanks Kevin shade
