Ok, this is for all the manufacturers out there. Why don't we have a rear bagging walk behind?? The side bags just get in the way big time! Trac Vac is costly, complicated and cumbersome looking (to me). How hard can it be? Hell, my 21" Craftsman has one! LOL! Seriously though, seems to me that it has to be possible somehow. This is the year 2001. Soon we're all gonna be hovering around. Surely someone can design a commercial walk behind mower that can do the same things that a 21" push mower can do?! What do ya say guys? Thoughts?
