ABSTRACT:
A self propelled lawnmower protective component used to support the grass catcher door is formed of a plastic material that is more flexible than the polyethylene material used in the prior art. By using co-extrusion, two different plastics are extruded into one shape. When applied to the lawnmower structure, the adhesion between the basic profile and a co-extruded ball or flap is extremely tight. Metallocene olefin is the plastic material which, when compressed under load and heat, recovers its original shape, similar to a soft rubber product and still has the capability of adhering to the polyethylene profile, so as not to separate after continuous or repeated use.
