Looking at walkers,navigators etc I see that Grasshoppers have rather large collection units and dump from the seat. Ive only seen one crew use these mowers and they seem to be a good bang for the buck. And can also discharge clippings if needed. Large yes, but I hate having to dump every pass especially in leaf season. Scag seems to have the largest capacity 3-bag unit which has its merits also. Sorry for such a common themed thread as I didn't find to much searching around. Thanks!
