Mower Trailer

Its economy is a trailer that has a slide up the tailgate. Little black trailer that you pull behind mower for leaves and dirt and others. Any help would be appreciated.

Search for the trailer manufacturer's identification plate.
It must have all the information that the model number etc.
Then google the brand name and visit their website, they should have that information there, or at least an e-mail you can write to for more information.

try a local store mower or they have some extra or they can tell you the manufacturers and their number to get one!
