John Deere Riding Lawn Mower Standard Blades - 42-in - 2-Pk is rated 4.7 out of 5 by 61.
Rated 5 out of 5 by from A Good Purchase I have a John Deere D-100 mower about four years old. I have hit a few rocks over the years and decided to change the blades. I bought a 2-pack of blades and put them on myself. The old ones were very worn. It required some basic mechanical skills, basic tools, and a couple of hours of time to replace the blades myself. To get to the old blades, I removed the mowing deck from the tractor and lubed the spindles while I was at it. My only regret is that I didn't replace the blades sooner. I can tell a noticeable improvement in the cutting and with less vibration.

Rated 5 out of 5 by from Came pre-sharpened all ready for use I purchased a set of these blades in April 2013 and the blades are in a different package that is shown on Lowes website (as of the time of my review). The review before me indicated the blades were not pre-sharpened but the blades I purchased are pre-sharpened. I’m assuming John Deere is now shipping them pre-sharpened? The package was tightly sealed in durable plastic but I was able to see that the blades were beveled so before you purchase a set check first to see if the blades are beveled before you buy them. I installed them and they are identical to what came with the tractor (LA 135) from new. Did not use them to cut yet but when I engaged the PTO I had no vibration & the mower purred just like it did from new. If the blades do not provide a good cut I’ll send an update to his review.

Rated 2 out of 5 by from Not ready for use - manufacturer blade I bought this blade set assuming it was ready to go! The blade was sealed in the manufacturers' logo shleve (John Deere). When I got home and opened the package I discovered that the blade was not sharpened. I even went to the lenght to call John Deere customer service to ask if this is usually the way the blades are packaged. They said yes. I have owned walk behind mowers and purchased blades before that were "sharpened" and ready for use. On a cost basis two 21" blades versus one dual package for my 42" riding mower cost the same. However if I have to finder someone to grind the blade from scratch it overpriced. I do not have a grinding wheel and you cannot sharpen a blade from scratch without one. Doing it with a file does not work. It would be nice if John Deere would sell parts (blades) that do not need addition "work" to use!!!!!!!!

Rated 5 out of 5 by from blades easy to install and the first cut is always the best.

Rated 4 out of 5 by from OK quality, higher-than-expected price The availability of original equipment replacement parts is important to me. You need the blades to fit right, and perform well. These blades fit on the mower perfectly. They seem to provide adequate lift of the grass, and provide a uniform cut. The quality seemed very average, and I was hoping the blades would have been much heavier. The price is a bit high in my opinion.

Rated 5 out of 5 by from 2-pack 42-in Multipurpose Blades Came on time and already have been used once. Perfect cut and work great. No vibration at all, well balanced.

Rated 3 out of 5 by from Blades needed Sharpening Blades are of good quality and great if you have a grinder to sharpen them with. I use a bench grinder in my workshop so it was not a problem. I wanted a hi lift mulching blade and this was listed as a multipurpose blade but is the exact version that came on the mower. They could be bolted on and used as they were, I'm just not sure how well they would have cut. Satisfied but remember they aren't sharpened! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from John Deer replacement mower blades I replaced my blades because I hit a stump with the old ones. Replacing the blades, with the right wrench size, was a snap. And the new blades cut better then my old ones.
