Hello Kye
I don't recognise this one at all.
There is something wrong with it though ...
The aperture or opening of catchers are designed to match
the chute size on the mower. The opening on this one is
enormous, and does not conform to any design I know.
My best opinion is that this is a backyard job made to
fit crudely to an unknown mower or purpose. It is even unclear
as to how it might have attached.
