Yep, still working and still with the same issues, though I might have solved it a little - earlier this week. I don't use it with the collector on the back, because it tends to jam the duct up with it's own cuttings, when ever the grass is too moist. Until this week, I have simply carried a stick, to poke the duct clear. ...
This week, I fashioned a U shaped a short replacement for the entire plastic duct, from stainless steel, so it discharged the grass back on the ground. The stainless steel was repurposed cooker hood duct, which was just the right width of U. My initial tests of the modification, suggest it's the right sort of idea, it just needs a deflector panel, or flap, added at the rear, to reduce the small amount of cuttings, still going out through the square hole at the very back.
