John Deere Mulching Kit Fits Many 54-inch Decks
Brand John Deere


54" mulching kit from John Deere. The mulching attachment allows converting the mower so it can be used to mulch grass or leaves. Remember you will have to follow the 1/3rd rule. No more than 1/3 of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height can't be achieved by cutting off 1/3, or there is clumping of the clippings, it may be required to cut higher; wait a day, then lower the mower and make a second pass. Mow at proper intervals approximately every 4 to 5 days.

 This kit includes two deflector ramps that are used to redirect the clippings into the blades for recutting. Specially shaped mulch blades with longer cutting edges that are designed to cut grass into fine clippings and direct them into the turf

 This kit also includes installation instructions. This kit does not fit 54C decks. If you are unsure which deck you have on your tractor email or call us so we can help you determine which deck you have.

Great Mulching Kit
This kit is so worth the money! I purchased an older 54" WB mower that had never been maintained and the cutting showed the effects of the neglect. I cleaned it up and sharpened the blades and it cut a lot better; however, the cut grass still clumped and was left in rows that had to be picked up. Once I purchased this mulching kit I had no sign at all of cut grass and it left my yard looking like a golf course. The best use, so far, I have gotten from this kit is the job is did on the leaves. First year ever when my rake didn't "leave" the shed!

We have an acre and a half just outside of town. My wife likes to cut the grass with our 54" JD 345 except for in the fall when we have to rake/sweep the leaves. I shopped around and found the Green Dealer had the best price, and the order was easy and on time. Original JD parts easily bolted right on using existing deck holes. This mulch kit works awesome. My wife never imagined that it could be so easy and clean, and we have (had) a ton of leaves!

Mulch Kit
Everything seems to be working. I did not have to drill any holes in deck. Took a little longer to install than I had read, but works well. Should have done it years ago.

Great Multcher
I have been bagging my 1 acre yard for many years because I do not like the look of grass clippings laying around, and I wish I would have bought this mulching kit a long time ago. The yard still looks great and I do not need to stop to empty the bagger multiple times while mowing. Even when the grass got a little longer than I intended, the mulcher still did a great job. I had to slow down a little while mowing, but it was still faster than dumping the bagger. Great upgrade!

Mulching blades
I wanted to be able to mow more with the tractor and less with the trim mower and this kit did the trick. I can now get up close to most anything and not have the problem of throwing cut grass all over. I don't have the issue of mounding grass after cutting but then my grass is not thick. Kit fit exactly as stated but I did have to remove some parts that were not mentioned in the directions. Keeping the blades sharp definitely helps.
