My only issue in cutting the top off the cup MF is I'm nor sure if it might start spreading. I have contemplated doing it over the years but I thought I would have to weld a ring around the top. They are not a bad mower for lawn maintenance where the lawn is cut every few weeks. I find catchers for them always an issue so I fit Victa catchers to them. Bit of work but it helps me get rid of the volumes of Victa catchers here and gets another mower out of the place
