Hey guys. I need to put new blades on my 12hp/38" Murray as my old ones are warped. Now, I can get some OEM Murray blades cheap but I'm wondering if I should upgrade to something better. How about "Gator" blades? Would these be a good idea for my machine? Are they stronger than OEM which are kind of flimsy? I only use this as a discharge mower, no bagging or mulching. Any suggestions are welcome!!
