I have a John Deere X300 bagger with a M120610 lid that has a bad seal. It looks like a regular (car type) weatherstrip. When ever I mow, grass blows up through the seal and I'm covered with grass. I checked on partscatalog.deere.com trying to come up with a part number and didn't score. Previous to this, I ordered what I thought was a correct part number and ended up with a UC12571; which didn't look like the cross section of the seal that is there, is about 20" long and is about 3' too short. Any help would be appreciated.
