Hey everyone, so I've been scouring the internet but have not been able to find an answer, so I'd much appreciate any information you could give me or point me in the right direction. I have a 5 year old Honda mower (HRR216k10VKAA) that originally came with a red plastic piece that you are supposed to insert when mulching. In one of my moves over the past so many years I've seemed to have misplace in, and I haven't been able to find it through any of my internet searches. When I try to mulch now, it creates clumps of grass on the right side of the mowing line and I have to drive back over it to get it to go away. I don't think this used to happen when I had this piece. Any suggestions on what to do or where to find this piece would be much appreciated. Thanks!
