Perfect fit for my Craftsman YTS4000
I have an older Craftsman YTS4000 lawn mower with a 42 inch deck. I've re-sharpened the blades so many times that it was finally time to just replace them. These blades are a perfect fit. They have the correct star-shaped mounting hole and are the exact same size as the original blades. They are sharp right out of the box, feel heavy and solid like the original blades and they do a good job of cutting and mulching my grass. I'm very happy with these replacement blades. These blades feel well-balanced and durable. I'm hoping I won't need to buy any more for a long time, but I'd recommend these to anyone with a Craftsman mower with a 42 inch deck.

Great blades for your ride on mower.
Loving these blades, they're cutting the grass a lot finer than the OEM ones and fit perfectly. Only one little thing, they come with no edge to the blade so you'll have to sharpen them yourselves.

Good quality heavy duty blades
These blades arrived very well packaged, each blade had a small rubber sleeve on the end of sharp edge to protect it during shipping. I’ve bought a lot of lawn mower blades over the years, and I’ve never seen that kind of attention to detail before. The blades came sharp, and the cutting edge is tapered at the proper angle to help maintain the edge. Most importantly, they feel heavy duty. They are almost twice as thick as the old replacement blades I previously purchased on Amazon. Overall, these feel much more solid and durable than the typical replacement mower blades. Very impressed with the quality and value for money.

Mine were slightly out of balanced.
Blades looked good. These blades are a high lift semi mulch blade and should work well in non-sandy soil. They fit well. Before installation, I checked the balance of the blades and was a little disappointed. I have three blade balancers, and all three blade balancers showed the blades, on identical sides, a little heavy on one side, which were easily corrected. For the DYIs, an unbalanced blade will shorten the life of your spindle bearings.

Perfect fit
Put an edge on all blades with a hand file. Mounted in the deck and WOW what an improvement. I didn't realize how bad my old blades were.

Make sure the model number is correct to the mower
The blades were too long. Had to cut them shorter. Take note, the model of mower was what I doubled checked, yet still too long and needed to be cut back. Disappointed
