Ty (Mr. Davis) is the main man on that problem, but he's not on much lately due to pressure of business.
You probably know how that catcher works: lift up the rear door by using the pivot lever on the right side, slide the catcher forward so the bracket inside the catcher on the right side supports the door, do a weird twist of the catcher to manoeuvre the bottom lip of the catcher around an obstacle on the bottom right side of the rear opening in the base, then slide the catcher forward while holding the thumb catch down. You know whether you have put it on correctly because the front top edge of the catcher drops all the way down to flush over the full-width ridge on the top rear of the base. If it does not drop all the way down, you did not engage the thumb catch correctly, and the catcher will fall off. It took me several mows to get the hang of it when I first got one of those mowers. Fortunately mine was a 4 stroke or I wouldn't have bothered, it would have been on the nature strip for the council to worry about.
