I own a Murray riding mower. I recently noticed my grass being cut a tad bit lower than usual and readjusted the deck. This did not fix the problem. I removed the blades and noticed one of the blades is bent while the other is severely cracked. I think its time for some new blades. I started browsing online for blades but most of them are plastic looking blades. I want metal blades like the ones I currently own. The part number for the blades is 495100. If anyone can help me find some metal blades I would be glad!
