1 OEM MTD 15 3/4" Blade, Circle Center 0.82",  #'s On Blade 742025041,  17A 023

All of the above information was gathered from the back of the blade.  Unfortunately, I could not find anything on google to help identify.  Other than MTD and the numbers, that's all I have to give you.  I just hope the extra photos will help.
