Rated 5.0 out of 5.0 by GOODBYE BAGGER, HELLO MULCH KIT!!! I was unsure if the kit would fit my Ariens mower (as my model number wasn't listed. As it turns out, I was lucky and it fit PERFECT! I can mow in peace and not get up to dump bags every ten minutes! May 5, 2015
Rated 4.0 out of 5.0 by Fairly easy to install; works pretty well The basic installation process is pretty easy; the blades are held on with a nut, and the discharge cover is held on with hooks and elastic. The discharge cover makes a loose connection with the deck and can be jostled out of place a little. Mulching performance is fine. I did not want the discharge shield on my [Ariens] mower to stick out past the deck, so I removed it. This was a little difficult because it required prying off the cap on the hinge pin. Then the problem was that grass and dust gets shot up through a little hole in the top of the discharge cover part of the mulching kit. My previous mower had a bolt-on discharge cover with no gaps or holes, and it worked better. July 11, 2012
Rated 5.0 out of 5.0 by Great addition to great mower Wow. Loved the mower. Then added the mulch kit. Super easy to install. And I can now mow the yard in less time due to no stopping and emptying bags of clippings. Lawn looks just as good as bagging. Great investment!! May 16, 2015
Rated 5.0 out of 5.0 by good product. did what it promised to do and i have had no problems with using this product easy for my son to install. not sure how much i can say about the ease of this installation May 5, 2015
Rated 4.0 out of 5.0 by great product (mulch kit) easy to install and a great value. makes the yard look great without having to bag the clippings. April 28, 2015
Rated 4.0 out of 5.0 by In Florida all you do is cut grass on the weekends! Package came quickly. Installed on my new Ariens 42" rider I bought at HD. This unit has several round tabs at the bottom I assume for a different style deck, I simply ground those plastic tabs off in a couple seconds and it fits flat. September 18, 2014
Rated 4.0 out of 5.0 by works well The mulching kit goes on easy and works pretty well. You can't cut too short or it will clump. The cover doesn't fit super snug so clippings get caught in it. Otherwise, it works well. Overall happy with it. July 2, 2014
Rated 4.0 out of 5.0 by Excellent Mulch Kit An excellent addition to the Ariens 42in tractor if you prefer mulching to bagging. We definitely noticed the difference since the blades repeatedly chop up our clippings and oak leaves. Out of curiosity, I ran the mower over a pile of oak debris and reduced its volume 10 fold. Less than 10 minutes install time, although I did have to close off a small hole where the spring clip attaches to the mower housing because of excess dirt and dust. I used a small piece of rubber matting and wedged it into the space. May 2, 2011
