I bought the 350 a couple weeks ago and it had neither, just a side discharge. I image because of covid all mulch control kits were out of stock and no shipping dates at the time i bought. In fact, i ordered a electronic one touch mulch kit from green tractor and was sent a note of what i wanted to do because no one had them and Deere had no production dates for new ones., I said leave it on back order and then the next day I received a tracking number. ??. I picked up a collection kit and chute and installed them the day i bought the mower. I have since received the electronic mulch control kit. I would like to put the mulch kit it on and have the ability to do either when i need to. The bagger kit said I needed to take off the rear mulch plate if i had it. I started reading about gator blades also. From what i read , Gator blades are not supposed to be used with a mulch kit because of their high lift. Can you leave the high lift bagging blades on with the mulch kit or use the JD mulcher blades for both bagging and mulch. Can you use the gator blades with the bagging kit the way its currently set up? Open for suggestions here from someone that's been through this.
