These blades are heavier than the Hustler Blades. I replaced the original blades that came on my Raptor and compared the weight.s by hand. I then put the new blades on and went and cut my yard. These blades cut better and even cut pver the original blades when the mower was new 2 seasons ago.. I would buy these blades again if and when I might need new blades. Best value for your money.
