Toro bagger fix

[Lawn Ranger Don]

I have a Toro My Ride 50 inch zero turn with a bagger attachment. Almost every time I go to open the back end, the whole back slides off. It has become a nuisance so I fix it so it won't come off. I drilled holes through those tiny stub it sits on and put a cotter pin in the holes. I did it to both sides. I can remove it easily to hook up my rear attachments.
