I have cub cadet 1040ltx riding mower. The blades keep catching the ground and bending. It's gotten to the point now where I need to replace the blades because they are so bent and dull. I have read reviews about the current blades that are on it and they all say this is a common problem and the blades are over all crap. Are there any other types of blades I can buy to avoid buying the not so good ones sold for the cub cadet???
