96145001102 Husqvarna Lawn Mower - Overview

Hi Anne, thank you for your inquiry. The mulch plug prevents the grass from shooting through into the collection bag. This allows your mower to shred the grass continually and eject it back onto your lawn. The end result is a fine layer of grass clippings that will act as mulch for your lawn. Therefore; a mulch plug effectively transforms a lawnmower into a mulching mower. For mulching, the rear door should be closed and the mulcher door should be closed and locked. We hope this information helps!
