Excellent blades for the John Deere E100
These blade cut better than the original blades did new. They are a little thicker, but only slightly. With all the debris we have in our field, this is added durability is welcome. Fit the John Deere E100 perfectly and were a much needed repair/maintenance job.

Great blades! With substantial savings!
I purchased these replacement blades for my 100 series John Deere lawn mower and found substantial savings compared to buying directly from John Deere’s website or dealership. After two full seasons of use, they’ve performed flawlessly with no problems whatsoever. Installation was straightforward, and the build quality has proven to be excellent. Based on my experience, I would definitely recommend these blades to other John Deere owners.

Fits JD D105 42" deck
They will fit JD D105, we all should be confirming our models to help others. They did need some clearance grinding on the blunt sides so they wouldn't interfere with each other. This was rather minimal on clearance-ing that I have had to do with every non OEM blades. I also took the advice on other reviewers and knocked the paint off the business end of the blades. I just replaced by blades with OEM JD blades this spring, but "found" a root that took out my spindle and blade, these simply cut better than OEM JD blades, and I had about 2 weeks / 2 hours of long grass to cut. This will be my Go-To set of blades for the foreseeable future as I just had bad results with others.

Longest lasting blades I’ve ever had
I purchased these June 21 of 2023 and I mow roughly an acre a week of thick grass and I’ve never sharpen them. I usually have to sharpen blades 3 times a year. The picture provided with this review was taken June 28 of 2025. They were still cutting grass but were starting to get dull so they got their first sharpening in two years. I’ve never had a blade last that long.

good price made of good steel and delivered on time easy to fit but the nuts were very tight (not the fault of the product) very satisfied with my purchase and would buy again.
