Abstract
A highly durable engine grass screen assembly is disclosed. The assembly includes a grass screen for covering an air intake port of the engine, a grass screen stiffening mechanism for supporting the grass screen, a washer mechanism for compressing the screen such that the screen is pre-stressed during manufacture and such that the screen remains in compression during engine operation. The assembly can include one or more stud mechanisms which are securable to either an engine flywheel assembly or an engine fan assembly. The washer mechanism, the grass screen and the grass screen stiffening mechanism are engaged in a secured fashion to one or more stud mechanisms. A method of assembling and positioning a grass screen assembly in an engine is also disclosed.
