Good blades, harder thanJD'S
I ALWAYS BUY THESE AND HAVE BOUGHT "NEW". THIS TIME I SELECTED USED, LIKE NEW. THEY WERE NEW, JUST NOT IN MANUF BOX. SAVED 5 BUCKS. 👍

Perfect Replacement!
Fit my D130 perfectly. Half the price. Mower sounds quieter too.

original blades JD installs
These are identical to what I took off my 1 yr old JD S130 from the factory. Note, JD hires Gorillas to put these on. My neighbor and I needed a 6 foot breaker bar to get these off. Heavy duty blades. Yes the entire blade is painted black but the paint will come off once you use them. They worked fine last year.

Nice fit on my 2012 John Deere D110, 42" deck.
These blades were delivered on time by Amazon in a factory sealed box. I will note that they are original Copperhead brand blades vs Maxpower but I had read that info from another reviewer before my purchase and this was not an issue for me as they are quality USA blades that are designed and spec the same... my one concern going with these was fitment and operation during rotation and I'm happy to report that these two blades fit my JD 42" deck perfectly with a slight clearance gap between blades so hitting each other during operation is not an issue on my particular unit. Imo, this product is a 4-star purchase.

Superlative Service
I can honestly write a review now. Once mounted on to the lower deck of our John Deer tractor, the blades effectively cut and trimmed our almost 2 acre property. No problems to report after last year's season.

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.

good quality
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.

Passt in den Sabo 107 S
Die Messer halten eine Saison bei 3000 Quadratmeter Rasenfläche pro Schnitt. Passen in einem Sabo 107 S. Kaufe keine anderen Messer mehr.
