Bearding

A build-up of grass leaf material and residue on a cylinder. This is a result of grass blades which have not been cut cleanly due to either an incorrect setting of the bottom blade to cylinder, a relatively blunt cylinder and or bottom blade (which will need sharpening / regrinding), or where a cylinder mower is used to cut grass which is too long for the setting, or just too long for using cylinder mowers, especially in wet conditions. The result is effectively a tearing and squashing-stretching of some of the grass instead of providing a nice clean cut.
