I picked up a HRR model refurbished from home depot while my toro commercial is in the shop. When you lift the lid where the bag goes there is a mulch plug that goes in the back. Do some people actually take this plug out and have the mower rear discharge? I keep hearing people talk about using the rear dishcarge and it just doesnt make sense. Why would you want the mower to rear discharge all the grass clippings all over you while you mow? I guess I'm not understanding something here..
