It is simply a plastic cover that goes in place of the drain pan. I find this expensive accessory for the so-called mulching function it provides. It prevents the grass out and forces him to be overlap with the blade. Effective when the grass is dry, but only if it is slightly longer or slightly damp for her flock. My engine has even started forcing k because I avaispas "ridden" on time. I deconseille given the price and inefficiency. If mulch is desired simply remove the drip tray.
