John Deere X300 Mulching Mower
Today I learned an expensive lesson about choosing the correct replacement blades for a John Deere X300 mulching mower. I own a John Deere X300 with a 42″ mowing deck. You can actually buy this machine with two different decks apparently, a regular 42″ deck or a 42″ mulching deck. All this time I thought I had the 42″ mulching deck, but thats because I have the regular deck with the mulching kit.
So if you’re looking to buy new blades for your John Deere X300 mower then you need to be careful which deck you actually have. The following is what you need:
John Deere X300 42″M (actual mulching deck)
- AM137330 – 42M Mulch Blade Kit, This kit contains a left and right blade.
John Deere X300 42″ (with Mulching Kit)
- AM137328 – 42C Mulch Blade Kit
Needless to say I’m not happy that I own these extra blades (One is actually the blade I need so it will be a good spare) but it’s my own darn fault. Hopefully this article will help others order the correct blades the first time!
