the ped mower i use the most is a 3 in 1 huski just like a proper mulching deck with a hatch on the side to fit collection bag or side discharge shoot. as for roller mulchers 99% sure there isn't one, if your cutting fortnightly in the summer you'll see the cut grass if its wet you'll see the cut grass as it clumps if i'm mulching i just spend 10mins with the blower to get rid of any clumps that may be left
i have some sites that take me 6 hours to ped mow imagine if i had to empty the bag all the time aswell!!!
not one single client has ever said anything about strips to me
i would say that all of my residential clients want it collected, commercial not so much, infact i don't offer them a choice, more waste = more cost and in a competative market muching is the way for me
rideons are all mulchers aswell
