Review: Before you buy mower blades please read! - OMG. What a difference these blades make. I have a 17 Y/O 42” riding mower (picture) and put these blades on it. It’s like going from a chainsaw to mowing with a Rolls. YES, it is that dramatic. I started the mower after changing the blades and immediately noticed the sound difference. I engaged the belt, mowed a few feet and thought the belt had not engaged the blades. So I disengaged, backed up and noticed that the lawn was perfectly cut. I engaged the blades again and listed carefully to the smooth sound coming from the blades. It was a very soft hum. Like a low whisper. The before and after difference is astonishing. The mulching action with these blades completely disintegrate the grass clipping. Forget bagging or re mowing to get rid of the clipping-pile rows. There are no clippings left! Seriously, these Gator style blades work crazy amazing. They fit my 42” deck perfectly, are extremely quiet, ( Hum rather that a roar) lift the grass almos like a vacuum. I will never use another blade again. A couple of caveats, they suck like you are mowing with a vacuum. A sort of “Flowbee” for the lawn. For that reason. Do not run over any objects, like a garden hose because it will destroy it. The second one is it will suck sand/dirt if you run over some. Yes, I recommend them, will buy them again, and would give them as a gift. Absolutely amazing blades! Great product, price, quality, performance, and function at an extremely low noise level. Get them! lol
Review: Good and thick - Arrived on time and as described. Perfect fit for my 46” husqvarna mower. Well made with plenty of lift for mulching. Cut an acre of leaves quickly turning them into ash. Sure it will do as well on the grass this season.

### ⭐⭐⭐⭐⭐ Great value for great blades.
*by D***Y on January 14, 2026*

These blades are direct OEM replacements. If not better than OEM. They feel slightly heavier than stock blades and mount just as easy to the mower. These were much cheaper than the big box store blades and perform well.
