Greetings, I am retired and have a 5 acre patch of paradise. I inherited my Cub Cadet lawn tractor with the house. It is a great mower. It has a double bag grass catcher. The tube that goes from the mower deck to the bag attachment keeps getting clogged by grass. It does matter if it is wet or dry grass it plugs after one or two runs up and back on my lawn. I’ve cleaned it out checked for obstructions but can’t get it to keep from plugging up. Any thoughts?
